Knocking

Post by pgjeepster » Mon Jun 04, 2012 11:42 pm



I read a post somewhere? about some front engine noise at cold start up that went away after it warmed up. I have a wing with 95000k on it and it does this I can feel the knock on the valve cover and on the timing belt cover on the left side of the motor until it warms up the sound is a deeper knock not tinny and sounds like it is knocking slower than the rpm of the motor it will quieten down with the throttle. Could this be a timing pulley? or tensioner? Regardless I think it needs to come apart should I start with the timing cover? Maybe run it cold with the cover off look for wobble? Any other ideas would be appreciated. Thanks in advance for your help.

I'd look first at the water pump.You will need to drain the oil and antifreeze obviously,but the pump is just 2 bolts right on the front of the block.
The bearings may be worn.They are not lubed by the engine and don't last for ever.
If there good,then it's just a few more bolts to get to look at the timing belts and idlers.

Might want to try some 20w50 oil if tensioners and belts look good.

I am running 20w50 Amsoil and she is real quiet now. Thought it might affect fuel milage but it still averages mid 40's.
