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...

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??

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...

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.

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 :)

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..

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
