i had the same problem but i installed a catch can and had the turbo rebuilt and no more smoke

[CheesyLobster]

This may be a dumb question, but is that an aftermarket map sensor?

[playr158]

is what an aftermarket map sensor?

a BOV = blow off valve = air release
a catch can = catches oil from the release valve (on top end) and drops it into a can instead of recirculating it into the intake....

[1900]

he should do a compression test and check if the piston rings are broken

[playr158]

ummm that wouldn't be the case?

broken rings dont' equal oil out the BOV


that IS a turbo seal.....

[nik]

so whats the update anymore pics ?

[playr158]

not yet

[dustin15brown]

I want more pics!!

Hold your horses. Make sure you a solving the problem and not the symptoms.

A turbo will bleed oil if:

-The return line is not being assisted enough by gravity

-The return line is too small

-The return line is clogged with contamination

-The feed line is too large

-The feed is at too high of a pressure (45~ psi is way too much. Aim for 15-25 psi)

-The turbo spins dry and burns up the seals

I would hate to see you go through all the work of replacing the seals just to have them wash out again.

[playr158]

do you really know what your talking about?

-The return line is not being assisted enough by gravity
an ideal return line should be completely vertical or no more then 30* from vertical this one is less then 30* if not nearly vertical

-The return line is too small
nope return is 10an (standard jgstools)

-The return line is clogged with contamination
brand new

-The feed line is too large
feed line 4an about the right size 3 is ideal

-The feed is at too high of a pressure (45~ psi is way too much. Aim for 15-25 psi)
oil pressure at the turbo should never exceed 65psi thats when damage starts to happen and seals go bad.....45psi is fine a little high but fine

-The turbo spins dry and burns up the seals
well if it was spinning dry it wouldn't spit oil now would it

i dont know how the turbo was hooked up but its good idea to pull the spark plug wires and crank the car over a few times to pressures the oil line and get the oil moving through the turbo i did this but left the drain line off to make sure oil was going through the turbo

the book helps doesnt player

[slipgun]

did you all follow the instructions with the turbo and stick your fingers in there when you first started it and hold it for a minute till the oil gets in there?

i did mine while the turbo was setting in the engine bay not hooked to the manifold but i havent heard about holding the compressor wheel

[presure2]

actually, player, everything he said IS true. all those things will make the turbo blow oil past the seals.
your sarcasam does NOTHING for these posts, also.

[playr158]

i never said it wasn't true cause umm i even said that was the issue?!

"that IS a turbo seal"

.....hence the reason why i supplied the piece of information to each of his questions......

the "do you really know what your talking about" was refering to the piston rings making oil come out the BOV.....not physically possible

did you guys ever notice how it seems that almost everyone on here blows their turbo seals on the 1st turbo they install? it seems all too common... there must be a common mistake in the install, oil lines, or something.... dont you guys think?

i think its the oil pressure from the feed line pushing oil pass the seal but then again not many of us are buying new turbos usally used ones or rebuilt ones on ebay

[Clement]

that just what i was thinking Lagos.......

[1900]

hey your problem might not be broken rings, but when i blew no. 2 piston on my car i got alot of blow by and oil would come out of the bov.
