[Doctor Gollum]

Seen a jag (the shite Mondeo one) v6 engine in for cam chain failure. Hideously complex chain routing. 3 differant chains iirc. Plastic chain guides. Worn chains resulting in stretch and poor running. Then ultimately chain failure where the U link had worn through. Clearly a softer link than the rest of the chain.

Iirc it had done 60k.

Bill? It was up over 1k and counting at the time.


Belts don't wear and stretch, but do perish and let the cords escape . But not until more than double the service life of the tensioner on omegas.




Interference engines are a result of higher compression to give better performance.

Belt every time for me, unless it's a stupidly simple arrangement such as on a pushrod engine. You're going to have to accept a shedload of slop in the timing then, anyway.

Yes, you have to maintain a belt, but that's a non-issue for me, even with the relatively short interval on the Omega, and at least you can get to it.

My Vw 5 banger is gear driven,actually so are water pump,a/c ,alternator and pas pumps,we don't need that lot going wrong

[78bex]

So why not run the cam drive belt into the sump oil for more efficency

Nah. Makes access more tricky. Like the Ford give crap about that.

Gear driven....chatter chatter chatter.....or if they have the spring loaded compensator gear set nice and quiet......until they age and then chatter chatter chatter

Yes,a little at cold idle but very quiet once revving(for an oiler)
