Bearings?

Riich · Mar 4, 2017

I've developed a vibration/rumble that feels a bit like when the engine is under load in 5th. It's not UJ's as I can feel it at idle. The engines got 205k on it, so I won't be suprised if it needs new mains, big ends and thrusts. I recently did the head gasket and noticed the bores had honing marks on them and there was little to no sideways movement in the pistons, so possibly been rebuilt in recent times?

Anyway, is it possible to do the mains without pulling the engine out or taking most of it apart? And if so, is thereanything else I can change while I'm at it?

If you get underneath you can change the big end bearings without taking the engine out.
However, for the mains it would still mean removing the gearbox, and the end-float spacers would need to be fitted to the crank at the same time

If the engine has been looked at bores cleaned Etc. Changing the bearings is maybe all that was done. If the mains are rumbling it may suggest crank wear is causing the fail rather than just tired bearings.

I'm gunna stick mi neck on the block

& say it's not the bottom end !

Else you would be saying your OIL light had come on

BEARINGS ! water pump / alternator bearings /belt tenshener bearing ! they only need a bit of play to start rumbling !

I had another look for anythink obvious and noticed there is a tiny bit of play in the fan, very small amount though.

One thing I did notice was residue around the injectors. I didn't take them out or change the washers when I did the head gasket, although I couldn't tell if it was oil or fuel residue. Could that contribute?

When I drove it today it felt fine and up on power too. Strange how they do that some days.
