Maybe try a leakdown test then you'd hear how much air was getting away and were it is coming from.
Definitely need drain bung above oil in pan. High pressure oil enters turbo from oil pump, and then relies on being able to fall into the large drain pipe. Sump pressure does not prevent the oil from falling, but if sump oil is above the bung then it will push up drain, and meet high pressure oil at the bearings. oil will then take the easier route out ie into intake or exhaust pipes.
Did the high pressure oil occur right from the start? Or maybe after a mile or so... Enough time to break a ring perhaps. Normally dip stick [on a Quantum at least] is a slopppy fit, yet doesn't leak oil; even with some blowby.
Is it happening because oil level is too high, and reaching the dipstick sheath?
Do you have a compression tester?
Hydraulic lifters can be duff from day one. Usually lazy, so they fail to lift the valve.
I don't understand why a faulty valve opening creates clack. Noise most likely injector issue. Try retarding pump a few pencil lines. What is the timing setting for a 1.9?
Good point.
It occurs about 5-10sec after start up. oil level is perfect.
Oil was coming out of the dipstick hole at the block like a foutain. Was deffinatly under pressure.
I am going to try to lower the oil level below the bung...(about 1qt) and see if this stops.
ACTUALLY...now that i am thinking about it when i was runing with the turbo off, to get injectors set and stuff, it was not leaking oil.....at all. but i never drove it. my oil problems came after the turbo.
I will see if i cant weld a bung into an old injector body and make a compression tester tonight. should have some results by tommorow. this whole time change thing is really messing with my schedule and cant seem to find time to work on it.
Stop talking about rings damnit! Ur making me more nervous about the whole thing. Tell me its a muffler bearing and i should just drive it.
