hi guys,

when i start my r32gtr - only on start up for about 2 sec i get this high pitch squeal which to me sounds like a fan belt, so i sprayed a bit of silicone spray...its not this.

what could it be?

if my explanation is not clear - i can record a short clip & post it here

The drive gear in the starter slips as the engine speed increases beyond cranking speed and it's not uncommon for them to squeal. Especially when they are full of clutch dust. Holding the key in start position for a second longer(ie allowing engine to reach idle before releasing key) should lengthen the noise if it's the cause.

so i sprayed a bit of silicone spray...its not this.

I wouldn't have used Silicone spray, you will never get the sh*t off the pulleys. The only thing worse than that would be Belt grip (makes me shudder just saying the name)

Just had a similar issue with my 33 GTR, Shouldn't really sound like a belt thou. More like a whine than a squeel. Mine was the starter not dis-engagaing after starting for a second or 2!! Very embarrassing in public places.. All i did was removed starter bolts and pushed starter back enough to get access to the gear and put quite a bit of graphite powder on and behind the gear. After about 5-10 start ups all gone ;-) Dont know what caused it to be honest.

Had previously thought about making a DIY to strip and re-oil but most out there will likely require brushes/bushes etc and didn't want to go too in depth. Removed/repaired an Sau members starter from 33gtr and there was a full handfull of clutch material in the housing and drive gear was bound up. Heaps of contact cleaner got it out. But greasing etc without disassembly would never have fixed the problem.

So that's a negative on four seasons lube. Save it for your next birthday:)

If you use your lube

yeah i did a full strip on it...didnt look to be in too bad condition..there was some clutch dust though...

I used grease but only on the cogs I think (still a mistake i know) I used something else on the shafts, was lithium or PFTE grease from a spray can from memory...

So whats the correct procedure then and i will do it again...

Fill both the bushes with oil then press your finger into them to force it through as they are porous. Grease on reduction gears which won't be where the noise is from.

Drive gear should lock up one way and free the other. Contact cleaner through the gap to get clutch dust out until its smooth. Touch of grease on worm drive under drive gear. Also touch of grease on solenoid pivot points. Noise will almost certainly be from drive gear if it's from the starter. If its still rough after cleaner get another for 30 or so

i still haven't gotten around to inspecting the noise i have BUT i did notice is that the noise is there when the engine is cold...once warm, the noise disappears which leads me to believe it is a noisy fan belt (or my supercharger belt as ARTZ commented above, haha)

Doubt the starter would be temp sensitive. Better check it out before something seizes.

    • I'm hoping I just don't have to do an engine rebuild NOW. Doesn't mean I won't do it at some point. I think a plus point is that the car presumably ran on or close to stock power nearly all it's life so far. Only the Owner I bought it from actually increased power with a standalone ECU and blew the OEM turbos. And after it got thee 2860s it wasn't driven an awful lot either.   That is what I meant. With the twins coming on so late (4500-5000rpm) I hope the rods won't want to exit the block prematurely. And it still being a 26 means the torque curve isn't gonna hike up all that much.   It didn't blow up on the dyno when they tuned it to 500ish crank. So I suppose it'll be okay for now. They did put a Tomei head gasket on first though which did not seal at all, and they redid it with a Cometic one. Which I hope won't be my water leak.   Mainly anything oil. So far all it has is the N1 pump, oil restrictor and a filter relocation kit with a cooler.
    • 15000? ish? Something like that anyway. It wasn;t so much a wear as a tear that then spread. Might have lasted a lot longer if not bothered by just one incident, whatever it was. I took a punt. They are really comfortable and do a good job of holding. My daughter HATED it when I first put them in, and probably still does now. She has sensory issues and hates the way they are all up your business. I'm 197cm and 95kg. Not fat or particularly wide, and the XL size seat is the rigth fit. If I was any fatter it would start to get too snug. Any skinnier and you'd possibly want the smaller width.
    • Mrs rs focus came factory with recaro cs  sportsters in it and they a pain in the ass to get in and out of with the really high bolsters, once you were in them they were one of the most comfortable seats I have ever sat in
    • The NA 2.5 has very little torque. You won't feel much. Those trannies are also a million years old now and it could well be f**ked. First generation electronically controlled autos will often refuse to kick down, ete, etc, depending on what's wrong with them.
    • Yes, but no but yes but no. Those "it's fine up to 500HP" rules and everything else like it were all determined back when the cars were 10 years old. As they are now 30 years old.....what do you reckon the chances of something shitting the bed are? I'd say they are much higher now than they used to be. You might be lucky. You might be unlucky. Spin the wheel and find out. Yeah, nah. It's actually exactly the opposite. Making boost early and having heaps of torque able to be generated right in the middle of the rev range will do more to damage an engine than having to rev it high to make the power. Think about the load on the conrods, bearings, etc, to make 400HP at 4000 rpm, vs 400 HP at 6500 rpm. So someone has already "let the Nissan out" which is how we describe the increased chance of a fiddled with engine to have had something done wrongly. Many more engines that have been opened die than stock ones do - even if you into consideration how they are treated wrt power levels and the like. Again, not saying that yours will definitely have been put back together by a moron. But the possibility does exist. It's still a lottery. Spin the wheel. What weakspots?
