Rb25 Making Funny Bearing Noise

[gfunkk]

yo peeps

my mates RB25 (s2) is all of a sudden making a funny noise kinda sounds like a bearing

it was fine like a week ago, hasnt been driven.. now all of a sudden this noise

tried unplugging vvt but that didnt fix it, it feels like its coming from under the rocker cover

the engine is stock, unopened etc

bit hard to tell from the vid water pump maybe?

[trel]

take it to a mech. asap! i wish i had gone to see one earlier. i started hearing a similar noise, took it to my mech, turns out harmonic balancer had come loose... left it too long and had damaged my crank

hopefully this isnt your problem.

it's definatley coming from around the head, not lower than that

but yeah the main thing is it was fine last week, cars been garaged all week then started it and this noise

This is screwed... i have just changed the spark plugs... but i took it for a few drives and it never made any noise..

Then a couple days before i moved overseas i started the engine and it was fine no noises at all..... so i dno how a noise like that could suddenly come up?

worst of all is i now like in U.A.E and im trying to get rid of the car soon as possible.....

Could be valve guides in the head.

Could be valve guides in the head.

i dont see how the valve guides could make that noise?... i dont think its the valves themselves because i bent valves and it make a different sound to that..... so i dont think its bent valves.

if valve guide were stuffed... then oil would be getting into the cylinders and there would be smoke coming out the exhaust?

I hope it could just be the water pump?

otherwise what sort of bearings are in the head?

Idler pulley bro.

It sounds SO much worse than it is though huh? I crapped myself when mine started doing it. But with mine it went away after the car warmed up.

Check out my vid:

Same noise more or less. I changed my belts/idler/tensioner, goneburger

When i had my r33 non turbo, it made a similar noise and i took it to the mech and found out the idler pulley nut was broken. fixed it and noise was gone.

it might be that?

if your not sure take it to a mechanic that is..... to me it sounds like it may be a few different things so best to take it to someone that can u tell u for sure and pinpoint the problem before it gets worse....

could me your lifters if u say it started doing it after sitting there for alittle while.

the timing belt is due anyway so doesnt bother me or the owner to change it, he's giving me $100 to do it anyway

its not the lifters i know what they sound like

[gfunkk]

update:

changed the belt, it had slight signs of cracks so good thing it was changed

changed the tensioner

changed the idler

all good now!!!

[gotRICE?]

Very common problem for the RB25 then

Glad its fixed. I was as happy as a goat on the other side of the bridge when mine went away.

[gfunkk]

yeah man the timing belt was a dirty job especially when it wasnt even my car but glad its all come good now

thanks for your help
