hey i got a r32 gtr, and i recently changed its timing belt and spark plugs.

i just started it and it idles good but wont rev over 3000rpm, plus theres a loud whining noise coming from the timing belt cover.

i tihnk i over tighene the belt, which is causing the whining.

any ideas why it cuts out at 3000rpm?

i gapped theplugs correctly, 1.1mm,

i also cleaned the afms with metho, would that stuff em up?

thanx

steve

thanx for the replys but ive foun the problem. it ended up being the afm wiring. i jiggled it and it fixed the problem. im gonna have cut the bad bit out and rewire it.

i also just sligtly loosened the timing belt but its still whining. i noticed that the belt is rubbing on the little cover on the crankshaft, its one that goes on before the main pulley goes on.

i understand its to stop the belt from coming off, but this is actually rubbing the side of the bellt of so you can see the thread.

how can it be fixed???

i replaced the two little plates that sit on the crack shaft and protect the timing belt(before and after the crank gear....only because i had such a bad time removing the pulley that i bent them slightly and was making the slightest whirring noise that drove me mad.

also apparently hi performance belts make some noise compared to geniune oem ones depending what they're made of.

There shouldnt be any noise from a timing belt.

Is the belt sitting in the middle of the cam gears and crank gear?

It shouldn't be running on anything.

The only thing that could possibly make a noise is the belt tensioner if the bearings are shot

Are you sure you haven't got the 'cover' (like a large thin washer ??) backwards ?? It will rub on the belt if it's not installed the right way round .....

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.

    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
