so i have a 2005 scion tc with a zpi stage 0 kit. i noticed to that my breater on the top of the engine has smoke coming out of it when i drive it a little bit.i havent been it boost for a while due to much slipping clutch. please help.

try a oil catch can

bigBOAT

could it be burning oil? from that. i have noticed a little drop in oil level

tCtCtC

is there any smoke coming out of your exhaust?

bigBOAT

yeah. a little white and black

tCtCtC

are you sure its white? and not like white/blue?
are you tuned?

first to say compression test! YES! I was that guy.

^^damn it! you win this time.

dude just save up money!!!! most likely ur piston rings are craked!!! this exact thing happened 2 me!!!

purplenitroustc

piston rings/piston landing

same thing

i had a similar problem when i was open dump but it went away when i put my exhaust back on obviously lol but the thing is, could there still be an issue of piston rings cracking?

I've yet to do a compression test.

this sounds crazy but yea open dump caused my turbo to leak oil like crazy lol - what happens is when the pressure in the chra oil flow is higher than the pressure on the turbine side it allows oil to pass by the piston ring seal - so putting a lil more back pressure on the exhaust and walla its gone lol

one edit - the turbine side oil piston seal was already pretty shot - it shudnt just do this easily Itll just make an existing issue very apparent

StreetStarsTc

hmmm makes somewhat sense, that is what i had assume that the loss in back pressure had caused it but at first i started buggin because i was like OMGZ everything just went boom but nope

yay lol

O yea it was a tnetics turbo too lol you might have the same issue - our high egt seems to create an issue for this turbo do to the oil flow design but apparently the water cooled chra will correct this - hopefully so because i have a tnetics turbo 50 trim thats sitting on my desk with water chra

StreetStarsTc

haha

well i do have the tnetics turbo with the coolant line, i do have a small leak, that could cause it as well....damn coolant lines

thendawg

iTrader: (2)

coolant shouldnt be able to leak through turbo to the exhaust its a completely seperate cast passage in the chra if its leaking there thatd be really bad it means ud hav a hole in the chra :/

StreetStarsTc

well i meant in the coolant hose that connects to the turbo, there might have been a few drops that got onto the dp or something hot that caused the smoke?

bigBOAT

so do a compression check. then go from there. but from what i reading here sounds like a piston??? f uck!

bigBOAT

and i would say the smoke is a little white and blue but not very ofter only when i get on it
