Could Really Use Some Help Sorting This Out
Posted 26 June 2012 - 02:32 AM
Engine went in 2 weeks ago, it fired right up first crank.
Now my issue. It'll hold oil at idle, but under any kind of load, it blows oil from random areas out of the lower half of the motor, heavily coating the underside of the car, and my rear hatch. I suspected a mistake in the pcv, went back over it on tues, all was clear and clamped. After a mild test drive, back window was coated with oil again.
Back under the car, looked to be the oil pan, re did that on weds, and double checked the turbo drain and dipstick seals. After another drive, same conditions exist.
Spent the weekend rechecking everything, making sure i didn't leave a towel someplace it shouldn't be, went over the vac lines again, pcv was gone over again.
Is there anything I'm forgetting? I've been searching, i found some similar threads, but nothing all that close to my issue.
I'm at my wits end with this, any help is appreciated.
Thanks to all in advance>

Thoughts that come to mind; What sealer are you using for the Oil Pan? Volvo pink? Your PCV was brand new, not old and clogged right?
You say the lower part of the car, so i lean towards the RMS, but you replaced it...never done mine, but, if that didn't go in just right, it's possible.....
I would lean towards an oil cooler line as well, but, it should be fairly noticeable.

I've been playing with these cars for a little while now, and I have never run into anything like this. I'm beginning to wonder if the block is cracked.

Now I know you said you checked that, but I'd figure the same procedure. Have someone rev it while you look under and from above. Lay cardboard down, and you can also hold pieces of cardboard behind the engine to try and better pin point it.
There's only a handful of places I can think of that oil is under pressure. The turbo, it's two hard lines, and the oil pan seal would be my primary guesses. And I'm going to venture a guess that it's your oil feed pipe to the turbo: it is either hairline cracked from stress/bending, or the copper crush washers don't have a good seal.
I really need to make a new sig pic. Nahhhhhhhh

This, along with a cracked turbo drain pipe caused this whole dilemma.
For now it's dry as a bone.
Too hot today to crawl back underneath it, look at it tmmrrw. Hoping for the best.

Finally, no more smoke, no more spray on the back glass, and no more spots on the ground
Cant believe a tiny crack, and a botched seal beat me up this badly.
Thanks to all.
