2 Symptoms of Engine Oil Burning

#shorts #motorcarnut

[alfredomarquez]

YOU FORGOT THE THIRD MAIN CAUSE: A badly designed "Crankase Ventilation System" also called a "PCV recirculation" that allows too much small liquid oil droplets to be aspired directly through the intake tract into the intake ports... The symptom is an intake manifold that is internally fully wet with oil, with tar and sludge from degraded oil on the internal surface of the intake ports and valves, forming a lot of carbonous deposits. In those cases, installiing a well designed "Catch-Can" will trap a lot of oil before it goes directly into the engine through the inlet tract.

To distinguish between a large oil consumption through the valve guides, take out the intake manifold, and look carefully if the color of the intake valve stem appears to be slightly "golden" instead of clearly bright silvery color of a clean valve stem, showing a yellowish or slightly golden or light brownish color due to oil seeping down through the valve guide seal.

Finally, most cases of excessive oil consumption result from a varying combination of the three causes:
1) Through valve guide seals,
2) Through low-tension oil piston rings, and
3) Atoo simple PCV or too direct recirculation (especially on overhead valve camshaft engines), that produce a lot of oil froth and mist of oil that is carried over to the intake manifold by a badly designed PCV sytem, or lack of proper baffles under the valve cover, that allows too much of the oil being splashed by the overhead camshafts to cause an oil "mist" (too much oil droplets) to be carried by the PCV recirculation into the engine, instead of "only oil vapors" - a stoopid assumption by engine designers, as oil at a proper engine temperature, WON'T produce almost no "oil vapor", but a lot of LIQUID oil droplets, that represent a sizable oil quantity going into the engine intake tract!

but it still can be the valve guides, I overvalued a 2.2. Mazda 4 cly and I ordered a supposedly good cly head from a wrecking yard, supposed to have been rebuilt, I could see the new seals, and completed the rebuild, it ran for 45 min after the build and didn't smoke, but owner reported the oil usage, I figured well, OK it should stop around a few hundred miles, since it was honed and thus is a mistake, the foreign cars have a dam good hard cly sleeve and they usually smoke after being honed, especially if your using chrome molly rings. but with the valves, I took it apart and all of the valve guides were shot, so much wear you could wiggle every one, like throwing a hot dog down the hallway. sobs, knew thus and figured a simple seal kit would suffice, I traded the old head, and that was a mistake because all it needed was an exhaust valve, it didn't burn oil at the rebuild start, it had 3k and 32 thousand. never burned a drop, it only ran on 3 cly for atheist 1k said owner. so we got the original head back and I bought 1 exhaust valve for 7 bucks and even used the old valve seal and it runs excellent now. that engine was very good shape, probably only needed the Valve and it would of keep running for a very long time since even the bearings and rings were like new.

My old Jeep Patriot has over 300k and dont know how but it still doesnt burn oil or puff blue smoke at start up. Changing your oil will surprise you if you do it regularley although I did have to replace the head gasket last year so its not like that will solve every engine related fix it will keep er going a long time even an old cheap Chrysler engine like mine.

How do you remedy this?
Great channel btw

E55 amg burns a quart every 200 miles or less. Car has full power and the cylinders look ok, i borescoped them. Should i change the valve seals first and then see what happens ?

Hi bro I have recently overhaul ( rings piston valve etc ) my honda civic 98 d15b non vtec engine and completed the 800km its time to change the oil now I'm confused which oil should i use mechanic said use 20w50 as per my knowledge of oils i thing 10w40 is better atleast we get some advantage of overhaul im very confused need suggestions ..thanks

What about a timing chan tensioner cover ? Could that cause oil to burn ?

I have a hyundai santa fe. Over 120k miles, just replaced the PCV valve last month and did a fresh oil change. Now 30 days later, my low oil light comes on. No leaks, no smoke. Why is it burning oil so fast?

[EliHernandezy]

Have a Mazda Protege that seems to be burning oil. No smoke at startup, but I loose oil between changes and my muffler tip is coated in soot

[brianr]

Mines smoke after sitting at idle for about 10 minutes... it doesn't smoke when first turned on.... do u think that's the piston ring

[bmartin]

Curious if you’ve tried a BG EPR treatment during oil change? Results from other folks seem to be very positive as far as clearing up stuck piston rings causing oil consumption on gdi engines. I’m getting ready to try it myself on a 2.0 gdi Elantra that burns roughly 1 quart every 1k miles…

I have a 2003 chevy trailblazer, runs thru oil 170k milez on it watz ur suggestion to chec on first

[Rns]

Got my E39 M54 straight 6 oil consumption changed pcv and all but can't figure out why still consuming, no smoke either

[jbenduro]

I have an audi s4 3.0t it burns through a litre every 700km no blue smoke when driving but when i rev it i get like a little puff of black smoke

[Slep]

what about blue smoke only when Full Throttle? my car does not blow blue smoke when idle or casually driving, but everything above 4k rpms it starts emitting a lot of blue smoke. Any feedback is appreciated!

[bob-prye]

Next question.... Can they go a long time like that ? Like 200, 000, miles ?

[Jayty]

My car oil is empty in just like a week and no leaks, no blue smokes. Whats going on?🥺

[Hesifilm]

My kia rio 2006 every 1000 kilometres 1 liter oil Los why?😢

[HugOCovers]

My bmw x3 2.0, 2005, use oil.. But never show smoke.. Could be because have particle filter?

I have a Cls 320 (w219) diesel and for example when i turn on my car and ehen i drive sometimes it blows white smoke, after driving for 5-10 minutes there’s no smoke anymore, but will do it again if i turn off the car, finish my things and turn it on will smoke again a bit and after driving goes away
