I wonder if some of the turbo guys can help me.
I have this small smoking problem with my m10 turbo. The car is used on the racing circuit. What happens is when I lift from full throttle to brake for a corner, and while I "heel and toe" there is puffs of blue smoke present.
For instance, I am at full boost down the main straight, I lift off and brake, and when I apply throttle again to power out of the corner there is just a puff of blue smoke and then it is gone again, until I put the engine under heavy vacuum again.
Now my question is, has anybody had the same symtoms? Could it be valve stem seals, or guides or the exhaust seal in the turbo itself? The thing is, the turbo has been reconditioned but still there is is this puffing under vacuum. This only happens when everything is hot.
When the head was ported, the guides has never been replaced, and I have always had this problem from day one basically after doing the turbo conversion?
The oil pressure to the turbo is more or less 50 psi and the oil return is 18mm in diameter. The return slopes down evenly and returns above the oil level.
Help me out please
Thanx
