Hella Blowby? WTF?
 

I finished my turbo project for the 2nd time a couple weeks ago. The first time I cheaped out on the feed lines and they blew off. So I fixed the lines and put a needle valve in place this time. I go to take the car around the block and everything is good for a few minutes of driving, so I mash the gas and BOOM, no boost whatsoever... I'm thinking whatever, a charge pipe leak or something. Then the car starts smoking like crazy and I pull over. There is oil EVERYWHERE, I mean all over the engine bay and just gushing out, but it's not coming from the turbo or the line connections, and the head gasket isn't blown. I think the is a line of oil comming from the valve cover and maybe the oil pan gasket but I have no idea what's going on...

The oil was all over the radiator, and behind the engine also, just friggin everywhere.

I've since removed the whole system and it runs n/a with NO smoke and a slight oil leak from the tuner toy fitting that I have yet to tighten. if anyone knows wtf could be up I'd appreciate the knowledge.

the breather thing on the valve cover is completely open btw.

Re:Hella Blowby? WTF?
 

did u use teflon tape on your oil connections?

Re:Hella Blowby? WTF?
 

I used that teflon goo stuff.

Re:Hella Blowby? WTF?
 

aww man the goo stuff sux ass on liquid it doesnt harden enough to seal never use that unless its gas like propain and such ......use the tape much better solved all my oil feed problems and so did LB weld ;D

Re:Hella Blowby? WTF?
 

Sounds like your pressurizing the crankcase somehow. Make sure you didn't have any line running to the valve cover. Maybe oil was coming out your open breather.

Re:Hella Blowby? WTF?
 

should I disconnect the pcv valve also? I mean if it's bad wouldn't that cause oil to shoot out the pan seal? I'm at a total loss as to where the oil is comming from, the entire enginebay is soaked, mainly the radiator.

Re:Hella Blowby? WTF?
 

you have no line on your breather line?/

oil will spurt out there if u have nothing on there.

Re:Hella Blowby? WTF?
 

yeah, I don't see any oil coming from there, it'e pointing towards the intake manifold away from the radiator which is where most of the oil seems to be splashing against.

Re:Hella Blowby? WTF?
 

This has happened to me when I broke pistons, the blowby was pressurizing the crankcase and oil was everywhere. But I hope that's not your problem :-\

Re:Hella Blowby? WTF?
 

hehe yeah me too... I've only boosted twice on the car and it's done it both times but my compression is good on all cylinders. I'm beginning to think the rusted out pcv valve has something to do with it? I really wish I could sell this whole setup and find a vtec head to work on, but boost keeps calling me....

I'm also beginning to suspect the turbo seals themselves even though I had a need valve in place, I found oil in the compressor housing and I can't blow through the oil passages, seems like there's a clog or something in there.

Re:Hella Blowby? WTF?
 

I think it's the turbo for sure now... I removed the compressor housing and sprayed some lube on the bear from the oil drain hole(bearing was black,still spins), as soon as I moved the compressor wheel I noticed about 1-2 mm of shaft play side to side and the lub started pouring out the compressor seals. I figure if that much oil was in my compressor housing it would smoke like a beast. There's no in/out play on the turbo so I'm guessing just replace the seals? the turbo spins freely.

Re:Hella Blowby? WTF?
 

damn... i got the same problem.. oils spitting out of the valve cover breather fitting thing...

I have the car running and i cover the hole with my finger and wait a few seconds then let it go and it just shoots a ---- load of pressurized smoke out. When i drive normally it doesnt smoke that bad... but once boost kicks in... it starts to spew it out of the tailpipe too... that shits emberassing... i think im going to have to slap a new headgasket on the old Z6 and run that till i get all my new internals and just build this bitch up cause it needs it more than the other motor

Re:Hella Blowby? WTF?
 

not sure this is true; I just have a little breather filter on mine, and it's bone dry.
