Can a timing belt cover make knock noise?

[kris_stewart10]

Well there is a knocking noise coming from the timing belt cover? Could it make a knock?

This is really, really, really a good example of not being descriptive

I would say you could hear belt slap or ticking due to the movement back there but a knock (like rod knock as an example?) I would say un-likely. Your crank pulley could be slapping the cover if it was seperating as well.

You sure that "knock" isn't really coming from the oil pan?

What exaclty does the "Knock" sound like?

Perhaps the sound of knocking on wood??

Water pump? I just had to replace a water pump that was only 10k mi. old. It sounded more like a brake rotor on a lathe; "shing-shing-shing".

If it goes away at higher RPMs then it could be the timing belt tensioner.

sounds like belt deflection.

What if the noise get's louder at a higher RPM? I got told it was the timing tensioner.

Most of the time this could be considered true.

could be harmonic balancer (main pulley) also. There has been a couple of threads describing knock, rubbing ect that were discovered to be the rubber on the main pulley self destructing....

+1 the harmonic dampener (crank Pulley) can seperate and wobble causing it to knock against the lower timing belt cover. It happend to me a few times.

All of my timing is only 6 months old but they gave me these like head phone things and it was like really loud knocking coming from the timing cover but they kept saying we don't really no till you let us tear it all apart. I was like I will just take it home park it do some research first. So any help you guy's can offer would be greatly appreciated.

I think it mught be the harmonic balancer aka crank pulley cause it happened to me too where it was making a knocking noise cause the pulley was seperating where the rubber was and it kept hitting the the wall by the the body of the car.

Ok Thanks I will check that out today.

no the timing belt cover can't make a noise by itself, however if something is hitting the timing belt cover then it is possible. but there isn't really much more i can tell you with out a more detailed description

 

[kris_stewart10]

well i will describe the noise the best i can ....... it is like a louder lifter tick but it is coming from the head and it is a LOUD tick or knock.....

but i was looking at my timing belt cover and you can see where the belt has been rubbing on it....

but how would i check my crank pulley?
