Losing oil through exhaust
#32
I am not a mechanic by any means, but the way I see it, that worn piston rings would create the conditions complete opposite of what i am having, by allowing all the blow by into cylinders and burning there. With all the blue smoke coming out of exhaust.

Also watched some videos. And the guy in the video was talking about clogging catalytic with oil from bad turbo. That was the reason I replaced mine. Oil was coming out of exhaust. So my question is it possible that increased back pressure from exhaust would create excessive blow by in pcv sistem?????

Compression (pressure) pushes past the worn rings and into the engine block. That excess pressure then pushes the oil mist out of the block via the PCV system.
Maybe it's just the picture, but that valve on the catch can system does look like it is backwards. The arrow should point to the intake manifold because that's where the vacuum pull is.

Thank you for explanation. If that is the case, that would be the first time I've ever heard all four cylinders loosing compression at petty much same rate.

Yes, back pressure causes the engine to work harder which can make more crankcase pressure if the rings are bad. To much back pressure and the engine can't run. Potato in tailpipe syndrome.

It's hooked up to the intake manifold which is a vacuum source. That means the direction of flow would be into the manifold.
The other side of that valve goes to the catch can. The can is connected to the valve cover tube.
Still looks like the block valve is backwards or installed in the wrong place.
