its a 98 z24 runnin fmu. no injectors or fuel pump. runnin 4lbs of boost. its burning oil really bad idk why though. when i first start my car it doesnt smoke but once its up to temp it starts smoking really bad. and there is no water in my oil. thanks for any help

where is it smoking from engine or turbo?

engine. its coming out my exhaust.

sounds like you messed up a ringland on a piston... that will happen when you dont upgrade fuel injectors or fuel pump...

I agree, but i would double check and make sure theres none in the intake, and that you just blew a seal in your turbo.

X2 could be too much oil pressure into the turbo.

im just suprised all this is happening it just got boosted and i have never even driven and gotten into boost. i have drove it around the block but i have never gotten past 3 grand so i dont really know how i could have messed anything up

It is not uncommon to have too much oil pressure into the turbo and blowing the seals out. More info is needed. What color is the smoke? You can try a resistor to reduce oil pressure to the turbo. Also where is your oil drain, draining to?



FU Tuning

its blue smoke. and oil drain is going back in the pan

Did you put it as far up on the oil pan or atleast past where the usual oil level would be? If it too low it could just get backed up in the return and blow a seal.

yeah its at the top of the pan. do think its possible that the turbo just came with a bad seal it is from ebay

Search (blown turbo seals) on Youtube ... That is your problem. Especially since it doesn't do it right off the bat but as soon as the exhaust heats up some. You have to get the turbo rebuilt . Sorry to tell you that but the same thing happen to me , I just finished my setup and got maybe 200 miles out of it before that happened to me.

yeah your right its just like the vids on you tube. thanks for everyones help im gonna order one tonight hopefully after this i can drive

woah before you replace those seals you might want to check your oil feed kit. the number one biggest mistake that people make is to fix the concearn not the cause. if you spend all the time in the world replacing your seals and put it back on with a feed kit thats blasting your turbo with oil, its just gonna blow your seals again.

what size restrictor do you have on your feed line?


"Kick azz is my boost hero!!! "

the restrictor hole is very small. so i wouldnt think oil would be the problem. but i found out last night my turbo has a one year warranty so im gettin another one soon

I should have mentioned that also. Thanks jcavi and you are 100% correct about that even though the damage is allready done. Once it smokes like that there is no going back the turbo is shot. I couldn't even get 1psi out of mine thats how bad I blew it.
