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 :D

hopefully this isnt your problem.

-trel

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. :worship:

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 :P

thanks for that man very helpful! i will get a gates kit and replace everything, its due for it anyway

let you guys know the results

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 :D

its not the lifters i know what they sound like

    • The R32 suffers from an instrument binnacle that is uncomfortably close to the design of a VN Commodore's. But beyond that, the layout of the rest of everything, and the materials (ie the vinyl coverings on dash, armrest, etc) are acceptable, and the patterns on the fabrics are not as blergh as those in the R33. And R33 seats are....quite unattractive. I know it's only small details there, but I reckon the R33 got worse than the 32. But the big blergh is the overall shape of the dash on the R33. It's just has that whole Maxima/Pulsar sort of look to it. Nothing special at all. Generic Nissan sedan. Whereas, at least the R32 dash/binnacle was different. Less a wide expanse of boringly curved plastic. More a "cockpit" sort of look, even if nowhere near to the degree that the A90 Supras got. R34 seats look good on their own, until you realise that they are indistinguishable from the shape and fabric on 70 other Japanese cars. And the foam bolsters on them suffer even worse than the earlier cars. Other than that I don't really have an opinion the rest of the R34 interior. I took the bits of the R34 I wanted (brakes and engine) and added them to the best external appearance Skyline in the modern era (the 32). So nyerr!
    • Can I be your first customer? I would like hard lines done for the fuel system, 8AN up and 8AN back and the underside wire wheeled and coated (brush or sprayed) with that black tar shit.
    • Speak for yourself, I love the R33 interior. 32 is blergh. I like the 34 interior too. Then you start getting much newer in most cars and they all turn back to blergh. 馃槢
    • 500-600hp into a RB is already 'sinking endless amounts of money' into an engine. Especially a 30 year old engine. Unfortunately this is the RB Game. Considering stock power (or at least stock components) will do ~360whp on 98 by simply turning up the boost on the stock gear on a RB26, that would be where I'd say the cutoff point for "sinking endless amounts of money into the engine" Cause to even do this reliably you'd probably need to replace all the bits anyway cause they're old, starting your sinking journey anyway. I reckon the least painful way is rebuilding the engine to make 50hp over stock lol. The 'plan your ownership around a rebuild' was a common saying 15 years ago.
