Hi ECU-MAN

Thx for the reply

shuould I try injector cleaner?

Could this allso make the engine burn oli?

Thx LukeZen

injector clean is always good
worn rings and valve stem seals cause oil burn

depends when it blows smoke.

under acceleration when you boot it

under deceleration and when you 1st start up the car ??

under acceleration when you boot it but not all the time only sometimes :rolleyes:

i would tend to say rings if its blue smoke.
it all depends on engine load.
