Hi, I just noticed some strange noise come out from the engine(CG10 1.0 16v).
The engine is fine for low revs, you cannot hear any knocking.
When the revs goes up, there are some knocking come from the engine sounds like the big end bearing.
There are two assumptions so far:
1.Big end bearing gone? I have tried using 5th gear at low speed and clamb a hill, there is NO knocking noise and the engine only done 60K, So I start to suspect somewhere else went wrong.
2.Timing? If the timing is wrong, Shouldn't it knocking at low revs not at high?? And the micra haven't got a distributor so you cannot adjust the timing by yourself?
Does anyone have any idea? I really couldn't define what the problem is...
Or maybe I just don't want to admit it is the big end bearing...
