chain has been hitting the cam cover

[maxclark91]

Took the tuscan out for an early morning drive after about 30 minutes had a mechanical/metal tapping sound from 4th but mainly 5th gear at low rpm 2000-3000 under load coming from the engine. Returned home removed the cam cover to find the chain has been hitting the cam. What would be this fix for this? A complete new chains down to the crank or half time bearing only? With the cam cover off I am able to move the chain up and down around 8mm with hand pressure.

Any advise, help or similar problems and fixes would be most appreciated.

I am a car mechanic for citroen and luckily they will let me use the ramps at work to sort the problem, just any advise is always welcome.

Brilliant cheers guys! Really helps!

Ahhh yes, well I was thinking of changing to the simplex chain now, I already changed to the viton gasket 3 months ago. And I did remove the cam cover whilst hot, that's when I had that much play, do you have pictures of the chain when re built with simplex?

I took the cam cover off about 3 months ago for powder coating, and I'm sure I didn't see any marks then, the marks also look fresh

Well I'm taking the car in tomorrow and taking the body off so the chassis can be powder coated. I am wondering if it's worth putting a Fff head on it or if it's even possible seeing as I have a 4.3 powers engine, got so m a ny decisions to make or whilst the engine is out do I get it rebuilt to a 4.5? But I suppose I shall have to speak to the experts on this, just think a 4.3 Fff engine would be a first!

A 4.3 and a FFF head might just be the ultimate speed six configuration....

I just need to speak to dom to find out if the Rev limit they put on is due to the the finger followers or because the crank is stroked.
