Hey there, when you say "rear of the engine" are you talking about the rear side of the timing cover? Does it sound like a knock or more of a rattle?
Customer: replied 1 year ago.
its more of a wuring/chaffing sound not as fast as engine not a knock not con rods not been short of oil .
Expert:  Jake replied 1 year ago.
Well a constant whirring sound could be an issue with the chain tensioner guide itself. The biggest determining factor would be to get a stethescope to pinpoint the exact location before making a final judgement.
Expert:  Jake replied 1 year ago.
Timing chain tension is controlled by oil pressure, when the tensioners themselves fail they have trouble building up pressure to keep the guide taught on the chain for good tension.
