Was autocrossing my Civic, seals blew on the t25 turbo, I'm puffing white smoke or steam out the tailpipe, also coming out of the crankcase and valve cover. I figure oil and water mixed in the turbo. I replaced the head gasket (just in case) and the turbo. Still smoking out the crankcase, then saw oil coming out the compressor housing, okay another bad turbo. Well, I took the coolant lines off the turbo, and changed the oil, just to be sure the crankcase stopped with the smoking. Well it didn't. I let it run for about 5 minutes that way. Still never stopped.

Is it possible that I still had enough water left in the engine that it could steam for 5 minutes veven after I drained and changed the oil? Or might there be another problem? The only other thing I can think of is the head possibly warped, and coolants still mixing with the oiil in that area. I'm really hoping thats not it though

 

Well I did a compression check. 1-4 = 60, 60, 80, 185. So I'm guessing a warped head explains everything. Anyone know a good machine shop in the dfw area?

 

Ugh, okay, it's not warped. I went all the way across the block and head with a .0015" feeler and a straight edge and never made it through. Anyone have any clue why my compression is a suck across 3 cylinders and I'm mixing oil and coolant? Please help, I'm totally at a loss.

 

you blew your oil rings homie and probably the other rings. the smoke is probably from blow by.

 

to make sure you blew your oil rings, do the compression test again, this time, open the oil cap and listen for air coming up

 

Can't beleive I didn't think about that. I just immediately assumed the smoke was water burning off. Makes a ton more sense now

 

Is it true that honing is required only if you can feel an imperfection, or is you have visual imperfections that go from top to bottom of the cylinders walls? My cylinders look uber-clean. Not one blemish I can see. So I'm guessing I don't need to hone?

 

I would do it anyway, you can't see every imperfection.
