Catch Can

Due to normal wearing of cars' engines after several tens of thousands miles hot gases from cylinder start to escape by the ring of the pistons inside the engine or on the other side of the pistons. Since the engine is closed by seals and gaskets, pressure starts to build up. Depending on how much the engine is worn, more ore less gas have to be released in order to obtain maximum efficiency. Also. Exhaust gases may have water and gasoline in them. Water would emulsify the oil and gasoline would thin it.

However those are exhaust gases and unburned fuel, you can't simply let them escape in the air. Most manufacturers choose an option design called PCV (Positive Crankcase Ventilation). It's a very simple idea. When pressure builds up (certain rpms and engine output) a valve opens (PCV valve) and lets those gases back into the intake manifold. The parameters of the process are more complicated, cause manifold vacuum that varies with the rpm and output. A simple valve is not the best solution but this is what we got on most cars.

PCV valve is usually placed on the valve cover in the highest point to avoid oil that splashes to escape into the circuit and into the intake with the gases. However that is an ideal that never happens.

Every time when i replaced a PCV valve i saw it had oil in it. And sometimes oil cooks in there and stuck the ball and spring of the valve either open or closed, again decreasing engine efficiency. But i never had a major problem with it until i owned a Hyundai.

Hyundais are different from other cars at least by two accounts. Valve cover is minimalistically low. Main design engineer there who worked at Daimler chose to copy an improvement from Daimler which they also took from diesel engines. The so called swirl flaps. There are two rows of butterfly like valves inside the manifold that open and close according to vacuum (first row) and actuated by computer (second). Those are installed in there to create turbulence and again get you a few percent of more gas mileage.

Now comes the interesting part.

I recently installed a modified filter for water to catch the oil from PCV line. The filter was transparent and i could see inside it's not only oil coming on PCV line. Oil is emulsified by the water present in exhaust. When that emulsion ends in the intake somehow interferes with the functioning of the first row of flaps, those actuated by vacuum. It changes the weight of the flaps on one end and they start oscillating, creating variations in engine's functioning which in the end translate in vibration. Vibration that surpasses the design performance of the exhaust manifold sealing gasket and starting intermittent exhaust leaks. Again vibration transmits to the hood that intermittently opens and let small amounts of exhaust pass by the seal and into the cabin fan intake. Shall i say more?

The filter i installed after a few improvements catches most of that emulsion however it restricts the flow of gasses at certain rpms decreasing efficiency.

The problem is known to car enthusiasts from race cars. There are what they call oil catch cans that costs up to hundreds of dollars. I once found a cheap one on Amazon made of blue anodized aluminum, looking nice and shiny, and... one quart capacity (hard to find a place under the hoos).

The lead's sealing gasket was made of cardboard and looked weak and i didn't want to take the chance for parts of that gasket to get into the intake so i sent it back. Drop of efficiency with installed filter is more severe in town and generally when accelerating when pressure builds up inside engine. I finally decided to build my own catch can. First i went to NAPA to buy some connectors. Had no idea what to attach them to. The idea was to go later to Home Depot or Lowes an buy anything that looked close to a can and had a detachable lead (you need a detachable lead because you have to screw the connectors). However, conveniently next to the connector there was what they call a "brake bleeder".

Don't know, in auto mechanics slang, for some reason they call purging of the brake fluid "bleeding". At Les Schwab they even have the so called "power bleeder" LOL. It's some sort of round reservoir with several gallons of brake fluid in it where at one end you attach a hose with compressed air and the other all sorts of adapters that go in the place of master cylinder reservoir. Pressurized brake fluid would go into the reservoir. On cars at each wheels brake caliper and pistons have a small screws with halls call again... "bleeder". You unscrew those a bit and usually can have someone press on the pedal to "bleed" the system then screw them back when the pedal goes up. With the power bleeder though, one person can do it. But it's very wasteful. The caps would not fit really well on top of master cylinders and much fluid is lost on the floor. However. You could purge the whole brake fluid from lines and reservoir and cylinder and replace it with new one.

The brake bleeder from NAPA works in the opposite way. You are supposed to attach a vacuum hose (supposed you have a vacuum pump) at one end and connect it to the bleeders at the wheels. Or just attach it and use it to just collect the fluid. While pumping on the pedal fluid would not go on the floor but in the can and air would go out on the other connector. Why it was there at NAPA next to the air connectors? Did they know i was looking for something just like it?

Anyways. It has a tight sealed lead, two connectors and it seemed to fit the purpose. However when i came home and cut those connectors which where too small and again would obstruct the PCV flow, i realized it was all made of cheaper plastic, not nylon as i thought. There is a serious chance it would melt at summer. While working at it was thinking of gluing those connectors that i almost self thread in the very tight holes i made in place of built in connectors, an idea came to me. Why not making the whole thing out of a... tin can. Drill the holes, force self thread the connectors, use JB weld to seal them and voila. Only trouble would be i would not be able to see inside and empty the can. Don't know yet.

Focus On Me

After the landscape guys came in Friday they blew some mulch in and partially covered one of the vents of the basement, the one i just cleaned the night before. The nearest to the exhaust pipes from driers where probably there's a broken one. I noticed in the last couple of days no new mole mounds in the yard, don't know about dog poo but it doesn't look like it smells.

Yesterday i vacuumed the apartment. Angela bought Fabreeze bags at Walmart (Bissel nr.7). However the're not as good as Arm and Hammer. Some dust went past them. I vacuum about every month or so, and when i do it it stinks in here about 24 hours. The new Winix filter i bought online from Home Depot has an air quality sensor. But what i call "the after vacuum stink" is not even showing on that one.

The guy with the blue Dodge, after more than two months break started to make the terrible noise again within last two days. Yesterday he started it and went for short trips more than 5 times, including after midnight. I think it stopped the day when i posted the picture of Ariana Grande's ex boyfriend saying he looked like him, the guy with the blue Dodge pickup.

After the old man upstairs moved in early September i haven't been using his parking spot next to ours. However other people started to use it and random cars where being parked next to ours.

So i decided to better use it myself. It didn't seem right for me to park it elsewhere and occupy a much sought for visitor's spot while others to use this one.

Two days ago a team of three maintenance techs went upstairs for about 10 minutes. It seem they didn't have a place to park their cart.

Yesterday they came again and dusted the garages next to our building. Something i've done once about 2 years ago. There was so much dust, back then it looked like they haven't been dusted for many years. Again they parked next to my truck, in the alley. In three years i haven't seen them dusting any of the building except once. I dusted this building three times only this year.

Today, after using that spot for about a month this morning i found a warning label on my truck's right door's window saying to move it or it will be towed.

I think the Dodge noise stopped after i posted this resemblance she showed herself here walking a dog, i saw here when i took out the garbage.

I think after what i posted in the last few days the're trying to move focus on myself.

Last time i saw a warning sign on my truck was in the evening of July 4th, when i came back from a trip in California. I came back a day earlier than estimated time because i drove almost 1000 miles in two days. The truck had a slashed tire and was to be towed the next day. A week later, after i put new tires on it, another one slashed. This time the drive of the towing truck looked like that guy from Patriot Prayer, Joey Gibson.

Had big problems with the new car. Oil was getting in the intake manifold through PCV circuit interfering with the swirl flaps, new efficiency additions taken from diesel engines. Oscillating swirl flaps meant engine vibrating, temporary exhaust leaks.

Got the car from an auction, Copart. It was sold under the category of "small dents and scrathces". However it was sold the second time. The car has been in a wreck, somebody bought it, partially fixed it and and sold it back in a different category. When i got at home i saw the engine was vibrating (because of oil in the manifold), there was a broken headlight and windshield reservoir in the trunk, car was painted on the right side including the door. Hood was slightly bent and out of alignment and was not making contact with the seal, exhaust getting in the cabin. Radiator's coolant cap was loose and leaking coolant, there was some sort of salt from the road crystallized on the windshield, etc.. https://www.copart.com/lot/29697838/?eid=email_G2US_mktg_transactional_BT_US_1007_Buyer_Seller_Counters_Rec



A few weeks ago i found a lot of oil in the filter in installed but after i changed oil i think it stopped. Last time at Jiffy Lube on 99 in Tigard they put by mistake 5W30 instead of 5W20 as recommended. Before that at dealerships in Beaverton and Salt Lake City they overfilled it and that caused small amounts of oil to flow through PCV valve. Every time i was getting in tire pressure was changed, including during the trips.

Exhaust and coolant in the cabin, poor driveability, all where potentially safety problems, and i drove it like that more than 5000 miles in two trips across many states in the west.

One of the guys of the maintenance team, the one who speeding with his cart in the parking lot disappeared after i posted this https://similarities-asemanari.blogspot.com/2018/11/radu-almasan-laszlo-barnak.html, and after i thought he just might have looked like him.

I think i've identified some of the others, as being some of the team of Christa Jakobson, ex-Chris Jacobson, ex Chris Brooks (not the famous athlete), a ninja instructor,  her(himself) acting as the handy-woman (middle of the picture). They seem not to be present here all the time. One of the guys disappeared after i posted what i thought to be his picture, he's got his own ninja school somewhere but i forgot his name now but he showed back about a week ago.

In this happy ninja group picture he might be the one on the lower left.


Just remembered now. This ninja dude from Christa's team looks exactly like Matt Bennett. Beware ninja use all kinda tricks with modified teeth.  (All current fighting technics in modern Japanese martial arts derive from ninjutsu which is at least 900 years old, however ninjutsu is much more than this and includes acting, other performing art, person substituting, disguising, infiltrating, mastering psychology, etc..)

Today as i was writing this post somebody went upstairs and starting making noises. That reminds me of the month from hell that started several weeks after the old man moved from upstairs, when they took out all the old appliances fainted, fixed cabinets etc.. for at least 8 hours a day in the morning. They were times when i simply had to leave because of the noise, smell, etc.. Angela just looked online ans saw the add for the apartment was taken out which means probably somebody is moving in and that explains the warning label on my truck. At least there was no squeaking noises upstairs for the last three months but that is about to change.

Octavian Goga, Petru Groza, aceeași persoană?

Născuți la 3 ani diferență, 1881 și 1883, amândoi au absolvit Universitatea „Eötvös Loránd” din Budapesta, deci vorbeau perfect limba maghiară. Amândoi politicieni, deși Goga ne este mai cunoscut ca poet, Groza a fost comunist iar Goga nazist. Groza începând din 1928 a lipsit 5 ani din scena politică exact când a fost Goga mai activ, iar acesta a murit în 1938, când a început cariera lui Groza ca și comunist.

Goga a luat cetățenia română la 250 mii sau o treime din evrei.

Groza a lichidat Partidul Național Țărănesc și toate celelalte formațiuni politice după 1947 în afară de Partidul Comunist Român și cel Național Maghiar.

În majoritatea fotografiilor de pe net Goga apare cu ochi mari larg deschiși  și capul înclinat înainte ceea ce-i micșorează bărbia iar Groza îi ține strâns cu bărbia ridicată și mai aproape de cameră. Am putut vedea în zilele și lunile care au trecut cât de bine colaborează celebritățile cu fotografii, atunci când e vorba de dedublări.

În rest scrisul pare identic, deși Groza face G-ul altfel. În mod ironic, P-ul de la Petru seamănă mai mult cu un O iar combinația G și r de la Groza simulează G-ul de la Goga.


Pe net am găsit doar o poză de rezoluție scăzută cu linia profilului lui Groza și una ceva mai bună a lui Goga

Știință și tehnică

Ce deliciu era în copilărie sâmbăta. Ne obligau la școală să ne abonăm. Aveam de ales între Urzica, Știință și Tehnică, Cutezătorii, Luminița, ce mai era. Minitehnicus. Primeam revistele și deși e totul foarte vag, îmi amintesc că învățătoarea ne lăsa parcă o oră să ne uităm la ele. Sau în pauze. Nu mai știu. Cred că le schimbam între noi și le citeam toate. Acasă taică-meu avea abonament la Magazin. Venea și ăla sâmbăta, mirosind a cerneală. Toate miroseau. Culorile erau cam aiurea, rezoluția, chiar și pe atunci atunci îmi dădeam seama că era proastă, pentru cele color ce se voiau lucioase. Dar erau câteva ore de imersie într-o lume magică, a viitorului, poate. Benzi desenate cu eroi locali. Mașini americane cu 5 viteze, circuit de frânare dublu care consumau 10 litri la sută.

Ce contează că aceste publicații erau făcute după cine știe ce model sovietic sau franțuzesc. Care la rândul lor poate se făceau după publicații americane.

Am aflat multe multe chestii de acolo. Nu prea discutam între noi, subiectele de discuție erau impuse de copii populari și de multe ori erau glume proaste, multe de natură deocheată.

Azi, după o facultate tehnică, după sute de mii de pagini de internet explorate, prin filtrul unui realism tehnic ca să zic așa, am învățat să recunosc din prima știrile, noutățile științifice reciclate, doar cu scopul de a corecta impresiile zilnice ale celor mulți.

Cred că H Pylori e un mit, ca multe altele. În realitate și în știri. Am fost tratat pentru H Pyori și nu cred că mi-a făcut rău fiindcă probabil aveam tot felul de alte infecții digestive, (esofag, stomac, duoden, pancreas, bilă, intestin) de la trăit în locuințe absolut sub limita igienei și de la consumat carne cu antibiotice. Americanii vorbesc despre lumea a III-a fără să știe în ce lume trăiesc ei. Ar trebui să meargă să viziteze orice țară din Europa să vadă, dar ei preferă o vacanță în Hawaii. Cel mai rău. Nimeni nu mă crede ce spun, nici ei fiindcă nu au comparație, nici europenii care se uită doar la filme, nu vin pe aici.

Mă uimește cantitatea de poze care descriu lucruri nevăzute, cu o rezoluție fantastică, dar nimeni sau poate doar specialiștii din redacții știu că toate acestea sunt doar imaginații ale unor artiști, care poate s-au consultat dar cel mai probabil nu, cu specialiști.

(Nu, H Pylori nu este verde. Nu are culoare pentru că cel puțin grosimea este sub lungimea de undă cea mai scurtă, violet.)

Iată o imagine de H Pylori la microscopul electronic. Microscopul electronic nu folosește lumină. Electronii, deși mult mai mari ca fotonii, nu sunt limitați la lungimile de undă ale luminii, sub care nimic nu poate fi "văzut", de aceea pot fi observate detalii, ca și cozile sau flagelele acelea.

Aceleași H Pylori la microscopul optic, cu un agent fluorescent.

Obiectele nevăzute din macrocosmos. Săptămâna trecută un asteroid exotic a bântuit știrile. O fi existând. O fi avânt traiectoria respectivă. Oamenii de știri au sugerat că ar putea fi o navă spațială galactică ieșită din uz. Au sărit să îl deseneze, iar unii deși pun o notă lângă care avertizează că este o imagine artistică, nimeni nu e atent la acea mică inscripție care de cele mai multe ori lipsește.

Nici un telescop, radiotelescop sau câmp de telescoape în uz nu are suficientă rezoluție pentru a vedea acele detalii. Din aceleași motive de lungime de undă a luminii. Ele, asteroidele în cel mai bun caz sunt văzute ca niște puncte. Din variația intensității luminoase se deduce viteza de rotație și cumva forma, în sensul raportului lungime-grosime. Astăzi nici un jurnalist nu se poate scuzat că nu a știut. Este suficient 2-3 căutări google pentru a te lămuri înainte de a publica ce poate influența mințile a mii de cititori.

Mă duce gândul la senzaționalism, care este un stil literar folosit mai ales în tabloide (publicații de exagerări mondene).

Dar motivul poate fi cu totul altul. Despre asteroidul Oumuamua ar fi putut scrie sau pune imagini senzaționale reale ca de exemplu traiectoria exotică.

Dar ei preferă exotisme imaginare dirijabile, care parcă toate converg spre o singură direcție. Simboluri falice, semantisme ca Oumu și roid. Iar România, acum, pylo.
