help please..
 

ok i took off the whole left side of the engine( accordian pipe, air filter, all that jazz). cause i had a feeling my turbo was burning oil because its losing more oil than wats leaking. there was a pool of oil in the turbo liek a small puddle, and the hose leading from behind the 3000 pipe to the turbo had oil in it. this hose is pumping oil into my turbo and i need to know why. does any1 know? what it is? the pic is below of wat pipe im talking about. its the small pipe that sits behind the 3000 pipe. any thing to help would be great. my dad seems to think it culd be a pcv valve problem? where is that located?

oh and 1 other thing. when i start my car up when its not warmed up, it idles at like 1500-1600. then wen it warms up it goes to about 700-800, normal idle. then if i shut it off and turn it back on in a little while it is still warm, it will idle real low, at liek 500 and starts to sputter and wants to die, but it never does.

yea, i kinda have that same problem. im pretty sure that its blow by that causes it. i have oil in my intercooler piping and right in front of the intake turbine. it is normal to an extent. i dont really know how you would fix it other than new rings.

new piston rings? i dont think those r the problem here.

come on guys

well, you said you were sputtering when the car got warm. so it could be that the oil from the crankcase is seeping past the rings into the combustion chamber and thats why your sputtering.


have you even checked your pcv valve yet?

and if you dont know where it is, you took a picture of it...
the pipe right behind the 3000 pipe is your pcv pipe

yes i know thats my pcv pipe, but where is the valve? my dad seems to think its the valve, but i dont know where the valve is, all the haynes book shows is the pipe also. so if any1 wouls like to explain to me where it is/how to check it if it is that/ how to fix it, i would be much obliged

and it doesnt sputter when it gets warm, it runs perfect, only when i start it after its already been running and then it sits for liek 10 mins it sumtimes sputters, but when i start it when the car is cold it revs high until it warms up but then it idles perfect.

I think i have the same problem so some help would be useful.

awwe cmon wheres the supra gurus when u need them

ok and my over flow bottle keeps getting filled up, and it never empties until i empty it manually into the radiator? whats up w that. and i dont burn coolant.

could be a bad radiator cap, or lets hope not ....the dreaded head gasket..

yup, same here too found oil in my IC pipes, intake pipes, and the 3000 pipe
jus a few more issues with my car

dood, just follow the pipe and you'll find it. its not rocket science

pull out a plug see if you have oil in there

as far I understand, supras dont have pcv valves, instead they have a fixed orifice on the throtle body where that pipe leads to.... that orifice happens to get clogged often..it is recomended to remove the pipe at the throtle body and clean the hole/orifice with carburetor cleaner/trhotle body ceaner and use a small pick or something to open the hole. also make sure the pcv pipe is not clogged up with gum...

hope that helps..

i didnt think there was a pvc valve cause all it did was lead to that little pipe. so would that make it rocket science? lol anyways, would cleaning that thing out make it stop shooting oil into my turbo? and any suggestions about the overflow bottle?

wont know until you try it.....

ok. i cleaned the thing out w carb cleaner and q-tips. and, the squeeky thing was my alternator belt, just sprayed it and it stopped. but, the filling of the radiator overflow. not a radiator cap, baught a new one. i thought a bhg makes u lose coolant, not gain it in the over flow bottle.

o and by the way, i put a k&n intakeo n my car. it makes the turbo sound much more high pitched, and the boost release is a lot louder too.

its common for supras blown headgaskets to slowly only under boost and those gasses push out or lets say they create higher pressure and consequently the rad. cap releases pressure. during that time ,the first thing comming out is the coolant not the gas since the gas is pushing the coolant.... and usually it only happens under boost or while driving, so dont let the car idle and hope to see the coolant overflow to get filled.....

i know, ive realized ive been making my car boost a lot mor, and its getting filled up faster now.

OOPS....i HOPE YOU HAVE MONEY SAVED FOR THE REPAIR...EVEN IF YOU DOIT YOUR SELF AND MACHINE THE HEAD IT'LL COST YOU AT LEAST 500 BUCKAROOS..... GOOD LUCK DUDE...

i dk if it is the head gasket for sure

easy killer.
no white smoke. burns a little oil thru the turbo. no milky oil. i dk.

On a properly sealed cooling system coolant gets forced into the overflow when heated and subsequently gets drawn back into the block through the overflow and radiator. Now if your overflow is filling up after you drive but after it cools its not going back to the level it was when it was cold, that means you have a leak in your cooling system and its drawing air instead of coolant when it cools. The leak could be in the radiator, heater core, water pump, any one of the numerous rubber coolant hoses, or it could be the head gasket. Im a huge fan of pressure testing the coolant system so I would recommend you start there if you are concerned about your cooling system.

Just to confirm, there is no PCV valve on turbo MK3 supras.
