147 2.0 TS knocking sound
I know there are plenty of threads about TS knocking sounds, and I should expect the worst.
We've had our '01 147 for only a year now, it's been looked after and oil topped up regularly in our ownership but I suspect the previous owner did neglect it slightly.
The engine has always run well, but starting to get a bit thirsty now and has always produced steam/smoke when pushed on. It's up to 97k miles which I guess is a bit low for 14 years old.
Last week it started making a tapping sound which only appeared above idle speed in time with engine revs. Not too loud, thought it might be a tappet. On closer investigation and after reading the advice on this forum I suspect the noise is lower down the engine and has gone from a tapping to more of a knocking noise in a short space of time.
More useful info: I knew there had been head work done in the past, so I checked the history in a bit more detail and found the receipt for the complete head rebuild (all new valves, stem seals, gaskets, belts, tensioners, big end bearings). This was 4 years and 30k miles ago so could this rule out big end bearings even if the oil level was neglected for the previous owner's 2yr stint?
I put her up on the ramps and have the oil, exhaust and sump off. Now, what am I looking for? Play in big end bearings? I will go ahead and try to remove them tonight if I get time.
cheers for the advice! :-D
