20v burning oil.... what could be wrong?
Thought i would throw the question out there.
i have no oil leaks, but i am obviously burning oil......
the 20v is a daily driver with stage 2 cams and EMS, not that that makes a difference.
thinking i might need to replace pistons and rings (as i may have done some damage running low on oil as my oil gage also shit itself)
also thinking of going turbo 20v, so if i do need new pistons i would prob go for some forged or something.
comments appreciated......
ze rings!

rings or valve stem seals
yeah it blows a bit of smoke.... especially when i floor it.... also running rich on aftermarket comp too....
blue smoke is rings
grey/black smoke could be running rich and valve stem seals - same problem as me
it takes about a day to do them, and whilst you have the head off you can do a TRD headgasket and check rings anyway.
also, shite oxy sensor will mean you will be running a crappier mixture of fuel/air and will be blowing smoke
Worn valve stem seals will permit excess oil to leak into the compression chamber under a closed throttle. The excess oil builds up in the cylinder and is burnt suddenly when you accelerate. This causes a fair bit of smoke to be noticed until the excess is burnt off.

Compression test is the key. Test all cylinders first off to get a base value. Then add a small amount of oil into each cylinder and test again. If the compression much higher than before, it's your rings. If little to no change, it's your valve stem seals.

what oil are you currently using in it? what the weight of it and how many kms has the engine done? how hard to push it also will help
i htink its 45w...... god knows how many k's the engine has done.... bought it with the 20v conversion.
i dont push it too hard, its a daily, not a track car (yet).
the weight of the oil does make a difference, as it burnt a lighter weight more quickly than the last lot i put into it.
