Hi Guys,

I'm needing to add a quart every hundred miles or so. No puddles under the car in the garage and no blue smoke or oil smell when driving. The front oil pump cover does seem to be wet but not dripping and it looks like a small leak coming from above the pushrod tubes towards the back of the engine is getting oil on the tin above the heat exchanger. But nothing major. Whaddaya think?

A quart every 100 miles would be leaving a noticeable trail under the car if it is just being lost from leakage. Might be a combination of leakage and burning some oil. Have you done a compression test?

1000 mile road trip plus 2 autocross events and no refill needed. Didn't even leave a dent on my dipstick.

How many miles on the motor?
How is your head venting system setup?
How is your case venting setup?

By setup I mean where is the oil going from those two venting systems?

151,000 on a 1.8, does not burn a drop of oil between 3,000 mile oil changes.

Not even a half quart between oil changes every 3k

Half quart every oil change is damn near perfect, full quart is acceptable for T4.
A quart every 100 miles is called fogging for mosquitoes.

Your rings and/or valve guides are shot, or you have a serious venting issue.

....with Mr. Henry & others

IIRC the owner's manual said up to 1 Qt per 800 miles is acceptable, but you're well beyond that, & it's going somewhere(s) you're not finding yet.

I see it's a McMark 2056 build, so why not call him for whatever needs done on it?

Otherwise Tangerine is close to NY.

Good Luck!

Thanks guys. Yeah, seemed really high to me too. Haven't don't a compression test but I will. Yes it's a mcmark 2056 from 8 or so years and 10k miles ago. As for venting, the hose from the oil tower goes into a baffled breather can, which is basically empty.

There is a thin layer of dirty oil fuzz on the bottom of the tranz and shift rod.

I'm thinking that maybe the oil cover behind the fan has a decent leak which really only shows up under pressure. The fuzz may be caused by the oil being slung backwards at speed. That and maybe burning a bit, but the car doesn't have that unmistakable oil smell. Really strange.

Yes, I'm close to Chris's place and will def take it there if I can't figure this out. Will also ask Mark.
