Hello all,
I have reached the point of decision regarding the timing chains and all that good stuff at the front there. I am not building a racing car, just trying to do what is right for the car.
It is a rather low engine XJ6 S2 engine and on disassembly the tensioner seemed to be in good shape with only a narrow gap from its base.
Is the established wisdom to:
1- If it aint obviously damaged keep it all (chains, sprockets, tensioners etc.) , cost $0
2- Absolutely replace everything (including sprockets) now since you are in there, modern aftermarlet parts are better/quieter/longer lasting, cost $700
3- Replace chains and guides just vecause , cost $100
4- Other… hours of measuring…
What Paul said… but just to emphasize - don’t be tempted to change the guides. The aftermarket stuff is very prone to separation and failure as well, like the Rolon tensioner. I just pulled apart a S1 XJ engine with low miles on a PO’s bad rebuild and the 2 top guides’ rubbers were completely off and all the others were getting ready to fail. Personally at this point I would only ever replace guides with something like the Rob Beere’s set. I don’t know who’s making guides for the suppliers now but they are a disaster waiting to happen. There’s not even a brand name to stay away from… Not worth the risk.
Here is what I’ve got.
The guides and tensioner show a little wear.
One of them however seems to show a small area of metallic wear.
Any thoughts on this?
