Subject: Re: Timing Chain ? by CFI-EFI on 2008/1/29 15:53:33
The timing chain drives the camshaft. That is it. The chain can stretch over tome and the sprockets an wear. A new timing set replaces worn sprockets and a stretched chain, for more accurate valve and ignition (on Gen I engines) timing.

Is there a pully near the cover for the chain and if it is misalighned or wearing out, it could rub a hole in the chains casing/cover causing the oil to leak out and lock your motor up? Vauge description
"Vauge" at best. There is no pulley that typically causes problems, but if the inertia ring on your vibration damper should break loose, it could walk rearward and wear into your timing cover. Any resultant oil leak should be rather slow. Oil on the floor and normal, periodic, dipstick checks should prevent any engine damage.
