Re: Timing chain noise Posted by SWEDECAR [Email] ![]() ![]() ![]() In Reply to: Timing chain noise, Tom D, Thu, 17 Feb 2005 18:34:02 Members do not see ads below this line. - Help Keep This Site Online - Signup |
The timing chain tensioner has a ratchet system where it moves to the next "click" when the chain is worn enough.
It could be that it is just "not there" yet and that the timing chain is slapping against the upper chain pad in valve cover.
That chain pad (rubber) gets very hard over the years and just by replacing that pad the noise could go away.
To really check for timing chain wear you need to remove the valve cover anyway and at that point it is a good idea to replace valve cover gasket and that chain pad and use a wrench on the intake camshaft and give it a slight "tug" backwards to see if you can get the tensioner to "click over" to the next level.
This is not that big of a deal and could be done in an hour or two and the cost with gaskets and such would be around $150-200.
