Fluctuating / bad idle

[SCP440]

P.S. If you do replace the chains, chain guides and tensioners, I would be interested in knowing if it was possible to do it with the engine in-situ. Mine is passed its scheduled change date.

It must be possible even if the radiator needs to come out. There are several videos on You Tube showing it being done in Explorers and the like. My guess the problem might be the cam covers in our cars as they look quite tight, a trick I do on the Jensen is to undo one engine mount on one side and put a jack under the sump to tilt the engine a few degrees, this gives enough room to get some parts off.

What is the scheduled change date/mileage on these engines?

On a positive not a mate recently had the timing chains done on his Audi S6, the final bill was just over £5k and less than £1k of that was parts. Apparently if he had left it any longer the engine would have been scrap.

Timing chains, tensioners, sprockets and guides is 150,000 miles according to Ford. MGR play the 'three-monkeys' and don't mention it. I assume back in 2004 they assumed that neither they, MGR, or any ZT260/R75V8 would survive long enough to find out that it should have been done !
