Noise From Cam Cover

[R33ram]

hey guys just a quick question...

have this noise coming from my cam cover.

when its cold sounds a lil loud with revs around 1200/1300 rpm.

when i rev it goes away after 1600rpm and when idling at around 900/1000 can just hear it a little bit.

as it warms up it goes away at normal temp and goes away...

heres a video of it similar to mine or almost identical to be honest at the last 25 secs of video.

100% from the cam cover as i rember month ago tigtning those allen key bolts there and got extremly loud then loosend them and went away but its back again.

any ideas would be great or help on this as a few people have had this problem after reserching it but all different opinions...

Might be the CAS, mine sounded similiar when I didn't space it correctly on a clear timing cover.

Mine did that too. I did the cambelt (tensioners, idler waterpump etc) and it went away.

Pretty common noise. Im pretty sure the idler is the culprit.

Yea mine has been making this noise ever since the timing belt was done but i had a entire kit installed bearings belt everything changed professionally now it makes this noise on a cold start and goes away once it's warmed up...

What's the worst case scenario is it something that should be fixed asap or??

CAS or timing belt/idlers

Pull the timing cover off, put the CAS back on and have a listen

maybe a silly question but am i gonna stuff anything up by removing the cover like timing and that or need to mark it...dont wanna stuff anything up and doesnt run ,??

yours sounds like idler, if you are worried get the belt tension checked it could be too tight, if you installed a GATES belt and had it tension to stock spec it could be over tight.. worse case the idler gives way...

[R33ram]

yea get it checked tommorow but hate taking it to mechanics as they are always like what noise lol

Is there any damage to be done or is it just a noise that gets annoying and no affect to engine besides that?

I did put a bit of wd40 or it got in there and became louder lol so most likley the cause is what you saying....

Yep was a gate's racing belt kit, if the idler gives away what will happen lol? Just not crank over or will it actually damage the engine on failure? If its just a noise i wont worry about it ... Was all done professionally so its all under warranty etc ill just blast the mechanic and they can cop the bill.

If the idler gives way you'll bend valves in the head when they smash pistons

[Hot33r8723]

Rebuild the head I had the same prob

Besides the noise it does on idle on a cold start ... would it get much worse before that would happen or would it just suddenly happen? I had the entire gates kit done doesn't that include new idler's etc?? paid 400 bucks be damned if it was just the belt they replaced... regardless mechanic would be at fault anyways since they installed the kit and did the timing etc??

Did you supply the mechanic the parts or did they suggest the parts and source the parts? Warranty might not stand if you supplied the parts...

I installed the kit myself did the tension up and it was sweet, no noise or anything for a good year, recently i had to take the belt of and when i started the car it made that exact noise but much louder, i loosened the tensioner off and the noise has gone, im not worried that the belt will slip or jump and it was a Cu*t to even get off and back on again.

Next time i will just buy genuine Nissan belt as their is nothing is wrong with them..

Yea im thinking that to should of got nissan ... im thinking its kinda overkill for street use gates... yea they sourced and recommended the gates timing belt kit they go through justjap i think.. as it was stronger etc

I always pay for a professional to install and source everything as im mechanically stupid in most area's lol... short of a oil change etc

*Just a update* on this guys, Had it checked again and the noise was the Timing belt which was actually loose.. and needed to be re-tensioned so all good now, cheer's

[Torques]

Hmmm

That is odd, how can the belt be loose?

I have exactly the same noise as you had, belt done months ago ..

Apparently the original mechanic that worked on my car was meant to re-tension the belt when i had the gates kit installed to begin with and didn't... The main mechanic "owner" said he had to redo the kit and tighten it as it was loose which is what was making the noise..

This is what i was told..

[Torques]

Ok .. cheers ..

I have a genuine Nissan belt, sounds exactly as your car
