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.

    • Thats the current state of the reo. Bit ew, but GTR Reo and supporting bars are $2000, and 2nd hand GTT ones are $1000... More engine disassembly. The good news is   Various LS weird sounds are apparently normal Everything coming out is in perfect condition The bad news is: Everything coming out is in perfect condition It looks like whoever assembled this engine ~25,000km ago was telling the truth with what's in it and how they did it. Even things I was unsure of like the timing chain - But it's a brand new double row timing chain, spaced perfectly. They even cut up the stock windage tray to keep it instead of being lazy and to work with the baffle. Cam, Heads, springs, LS7 lifters, Pushrods - All look new and have obviously been working perfectly. In other news, we removed the pineapples that were loaded below the superpro subframe bushes. They look a fair bit munted and have deformed the poly bushes that are 'above' them. I'm telling myself that now that there's space 'under' the bush between the little cup that bolts in... that having a pineapple wedged there was bad and basically made the rear end solid. The pineapple and the superpro bush are ... equally deformed (i.e they have deformed one another from being smashed together). We'll see how it goes with bushes only. I am sure this cope will fail and the answer will be to drop the subframe and put nismo rubber bushes in there instead. $400 worth of gaskets and ARP head bolts to replace perfectly new looking gaskets that absolutely weren't leaking  and were installed perfectly with great care - because god damnit.    
    • Why bother? Keep them under 1bar and be happy, I had it for 10 years and never had an issue. once you go beyond that the budget blows out fast and then keeps on blowing out 
    • I'd still recommend rebuilding the turbos too. That will eat up a lot of the budget especially if you aren't willing to put in the labor to R&R the turbos yourself but it's a huge risk to ignore it at this point.
    • Can't help it, its an illness. 
    • Yep, agree with all of the above added on too. I just love the age old "what boost were you running?" Question without getting any other surrounding data. IE, may have ran 20psi, and lived for 12 years, but it was an 80 year old granma driving it to Bingo once a week and never took it over 2500rpm.
