Ok so my 1995 300zx twin turbo has 224k miles lol Its bone stock, not an aftermarket part has been in my car, I got the car like 3 months ago so Im kinda new to the forum and to the twin turbo world

passenger side smokes a little on idle and under hard acceleration, I think its white smoke, but it could be blue smoke, I also have notice some oil in the passenger intercoller pipping. From what I understand it also could be a blown head gasket but I havent been using my car since it has a coolant leak that I need to fix and all the water from the system is gone so I only start the car for less than 4 minutes so because of these any water is getting into the combustion chamber to be burn and converted into steam
please help me figure this out

thanks a lot guys!!

Welcome to Nico!

From what I'm hearing, I would say the turbo has blown a seal. Start saving up, cause you will need to pull the motor to do it right. I would save up and do the timing kit and seals while it is out so you don't have to pull it again in a few years. When I replaced the turbos, I just replaced the center sections of the turbos call the CHRA. I bought them from CZP for around 850 shipped for both. I recommend replacing both turbos because of the age.

I know it sounds like I am just saying throw money at it, but honestly, if you cut corners on the above items, it will cost you more in the long run.

I just replaced the timing belt and seals like 200 miles ago, then coolant hose brok so I guess pulling the engine out would be the best thing to do, I just want to make sure its the turbo, is not my daily so its ok to have park I guess, I jusy wamt to drive it sometimes, anyways Im saving for the engine rebuild, but that will take quite some time lol, thanks for the quick repply
