AF too rich meaning too much petrol is it? cos i don have a fuel regulator or an SAFC to control the fueling. Shud i get one? my muffler is still new la...wat do u mean by turbo shaft? meaning the inside of the turbo rite? does it mean i have to dismantle the whole turbo to check the saft? intake piping meaning from the manifold or from the filter? i'm not really understanding here...wat bush are u talking about? bearing, oil seals? are these all in the turbo itself or external to the turbo wan? cos i'm not very very familiar...pls forgive me...
What you need to do is dismantle the intake pipe that lead
to the turbo(that one connect to air filter),that you can see
the turbo intake "fan",hold the ceter of the fan,which we call
it shaft,than check whether it can shake up and down or not,
if it does,that mean the turbo bearing/bush already wear off,
so the engine oil will leak from the bearing to the internal turbo,inlet piping then into your combustion chamber,then white smoke come out lah ! if it is a small leak , you might see
your compression piping,which is the pipe from turbo to intercooler to engine have sticky oil , if it does , then confirm
turbo leaking.
I think you can try to use a thicker oil like 15-50 or 20-50 ,
better use semi or fully sync oil, see whether can solve this
problem or not , but don't use mineral oil ! And becareful from
buying "fake/recycle" oil , I spoil two turbo before because the
oil that I bought is the recycle oil.
