So I have lots of smoke coming from the valve cover breather. I dont have a catch can hooked up. LS bottom b16 head. Stock internals on the block, built head. Running 5lbs of boost, tuned at alot more.

White smokey steamy vapor? Like the kind you get when you have coolant in your combustion chambers? Or coolant in the oil that is vaporizing? Or is it smoke from burnt oil?

What's the oil look like?

5 psi of boost... on what turbo check ur oil and coolant level

ay_billy

oil looks clean. coolant all there? Ill keep an eye on the coolant but no loss.
Its white smoke, i didnt see a blue tint to it though?
I let my car idle for 15 min to see if it would "clear up" but no. It had been smoking but not that bad from what I understand.
.70 trim jdm sport turbo. Restrictor on the feed line.
Water and oil levels appear fine.

White smoke is usually an indicator of water where it's not supposed to be.

bump im having the same problem exactly lol

ay_billy

Ok. Other then the head gasket, what else would cause water to get in the wrong place?
Is there a way to check the hed gasket without a leakdown test? I dont have a compressor at home

ay_billy

hopefully we get answers

Is it comming out of the exhaust to?could be valve seals or piston rings

Wrona

get a compression tester its cheap and do a compression test also u can get a block tester to see if u have exhaust gas in the coolant

ay_billy

Ok. I'll try to get a comp tester at autozone and put up results later.
How do you use the block tester? I had asked for a comp tester, and they tried giving me a block tester and some liquid??

what about to much fuel? like running rich?

Valve seals? Blown turbo seal?

That would come out of the tailpipe.

Sounds like blow-by to me. how many miles are on the block?

kyden

sounds like you cracked a ringland. compression test time.

there so many opinions here we need a video. I opened my oil cap and some reg smoke or steam came out not much....heard it shouldnt do that but every engine I seen around my place does

^This. How are you venting your crankcase? If you're running stock PCV system, ditch it ASAP.

It's excessive crankcase pressure and blow by most likely due to cracked ringlands. Blythe first post saying its tuned on a lot high boost pressure on stock ls bottom end and probably to much timing you cracked those babies real quick. Time for a tear down and rebuild and tuned properly

The block has low miles and we run the car at 5 psi, I believe that is how its been run for a while now.
Im going to run out and take a few pics, because likely, the turbo is coming off. :\

kyden

low miles and 5 lbs really doesn't mean anything though.

ay_billy

I cant see whats going on in the pcv system, Im going to jack it up in a bit, cause I cant see it from above. It is not connected to the intake manifold

It might be plugged? The bottom end was just replaced so maybe they forgot to put the pvc somewhere.

Wouldnt ringlands cause me to smoke bad from the tailpipe too?

Would this work?

I had the same problem with my stock LS setup. It was ringlands. Compression test should be able to show you. You want about +/- 10% difference in the cylinders. When I tore mine down (since one number was lower), it turned out like three of the pistons had broken ringlands.

Leak down test will point out the problem if it's engine internal failure. Turbo will not cause crankcase smoke only exhaust smoke. Crankcase smoke is from ringlands cracked, excessive blow by, or poor ventilation causing it to damage something else
