Z22yh oil issue 1ltr a week

Stephen82

Symptoms: using/losing 1ltr a week (50miles)

Z22yh signum owned it 3 weeks.

Thermostat was stuck open, inlet manifold was missin bolts and some finger tight. (So it's been off for some reason.)

Oil is clean in dip stick and in rocker cover. Cover off

Coolant is clean and circulating normal with not lose of fluids.

I can smell fuel in oil :-/

Oil breather gunked, attached to black plastic fly'n saucer thingy with a spring in the lower rubber pipe? No idea what it is, going to clean pipes and thingy..

Is the blocked breather causing back pressure and forcing oil somewhere?

Coolant bottle has signs of oil previously..

Throttle body is black sludge under butterfly

Please guys, somebody must have an idea.. Maybe it's leaking only oil when I'm driving? I'm gonna go check sump plug now. Ha maybe that's missing.

I have pics but can't post on here

there does appear to be some condensation in the PCV valve (plastic thingy), hose and on the oil cap.

Usually these engines drink oil due to the piston rings being worn or the oil scrapper rings being gunked up.

Thanks.. This is pretty much it.. I hope! But a clean? Or replace?

If a PCV is bad, you normally won't see burning oil. What you'll see is seals and gaskets failing. This can cause a loss of oil (and a very dirty engine bay). It's one of those things which can sneak up on you if you aren't paying attention. While a bad PCV is not a good thing, don't look here for a reason you're seeing oil smoke coming out the tail pipe. COST TO FIX: If you catch it before it becomes an issue, it's actually quite cheap to fix ... just replace the valve. If you see leaks at seals or gaskets, your expense goes way up, but it depends on which seal or gasket is leaking. Easy to get to seals or gaskets will cost much less, because the labor is much less. The converse holds true - Labor is a determining factor here.
