Hello all,
Ive done about 30,000km and i have always had a weird vibration sound that appears to be coming from the lower end of engine.
no idea on kms of engine, susupect rebuild at some stage due to compression results, but 30,000km i did the following,
overhauled head, timing belt and tensioner, didnt touch the bottem end at all. everything i put back seemed in good condition.
I am like 95% confident it is not an ancillary making this noise. it is definitely coming from the engine itself and towards the bottom.
this isn't my engine, but it is the EXACT same noise and description from the guy.
I found this youtube from this thread,
Which talks about the oil pump shaft gear bearings. the little needle bearings.
Those seem like a complete bastard to replace, engine out on a stand sort of job. I have a spare block here (but unusable) and it looks very difficult to replace those bearings.
Also seems very unlikely they would give any trouble?
over 30,000km it has not gotten worse. But my issue is i'm using knock ears to tune my engine and all i can hear is this friggen sound. Also i want to fix it cause its not a nice sound.
Do any of you m20 gurus have any input here?
