So here's another silly beginner question from a new owner of a TCS Lotus Europa.
I have only had the car a couple of monts so am still finding my way around and de-bugging odds and ends. Well I have noticed that at idle(900rpm or there abouts)there is quite a bit of clatter comming from the engine. Reve it up a bit (say 2,000rpm) and the clatter goes away.
So I conclude it could be a loose timing chain. Now I do the right thing, and read the workshop manual - which indicates there is an adjustable timing chain tensioner (yipee!). The manual goes on to say that the tensioner should be adjusted till any noise is eliminated (yipee #2).
Well I backed -off the lock nut and gave the tension adjustor a couple of turns, and indeed it does seem quieter.
But my question is, is there a more specific technique to adjusting the chain tensioner? How much should I adjust it, and do I risk over-tensioning the chain? And how much exposed thread on the tension adjuster is considered "normal"?
As usual, I am most appreciative of any advice.
