Timing Chains
Recently had a strange knocking noise form the front of the engine. Narrowed it down to in the timing cover. Looking down the oil filler I could see that the tensioner for the LH chain was "pumping" in and out in time with the knoc. Also the was little or no oil visible on the LH chain. Removed timing cover and videoed the engine ticking over - clearly no oil from rear tensioner, plenty from the front on. Removed tensioner cleaned it out and refitted it. Now plenty of oil flow and the knock- which was consistent and solid now varies a bit - but its still there!! Next step change the chains.
Look at the two videos: (caution they are large files approx 70Mbytes)
