Just installed a new clutch in my 89 GTR, exedy disk, valeo presure plate. Got it in and down on the ground with all new fluids, the thing will not go into gear when its running. Im have done quite a few clutches in my day, this one was not really any different, i dont know what went wrong. Heres what i checked and did before ripping it back apart. Ok so it wouldnt go into gear while it was running but it would when the engine was shut off. I tried putting it in gear with the car off, and starting it with the clutch pushed in, lerched forwards....checked the slave cylinder(its brand new only about 1000km's) lots of travel does not need to be blead. I used a bar to move the shift fork past the travel of the slave while having a helper try to put it in gear with it running, didnt work, didnt even try to go into gear. At this point i was getting pretty pissed off, i really didnt want to rip the tranny out agian. Had a few opinions, mabey the disk was in backwards, didnt think so but a chance, i had the flywheel machined at Lordo, mabey they took too much off? So anyways i pulled the tranny hoping id find somthing wrong(only took 2hrs to remove the second time) and have compared the new and old disk and presure plate and cant see any physical differences. Can anyone shed some light on my problem? Does anyone know the minimum thickness for the flywheel on a GTR?

thanks

Darren

Have got the right thrust brearing, I think with my single plates they machined the flywheel flat ( removing the 0.5mm step ) for the excedy clutch plate

The release bearing looks identical to the one that came out, and yes the flywheel has been machined "flat" no step

when you go to far with the machining on the flywheel the pressure plate moves in to and moves away from the fork to fix it you put a slightly thicker washer under the pivet ball where it screws into the gearbox

How do you measure for this? Its one hell of a heavy tranny for trial and error....lol

Its hard to measure and probly a last resort usely only done when every thing else has checked out, like fork is not split, bearing is right and put in properly, hydrolics are good and working fine then it might be the spacer and is best to take to a pro with experince on GTRs or trail and error and a bit of guestimating

      Have you put an aftermarket oil pressure gauge on and verified your oil pressure?   Noise being on the block, on exhaust side, how high up the block does it seem to be? It could be the VCT system getting cranky, especially if it's mainly at idle, and when warm, as that'll be your lowest point for oil pressure. Could be showing that oil passages / VCT solenoid are blocking.

      Well, hydraulic lifters will get noisy if they are dirty/fouled in some way, and exactly how that manifests will depend on exactly what schmutz is where. There is a procedure on here somewhere for dismantling and soaking/cleaning them. Replacing them with new is about 50% of the work and about 5% of the money!

      Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers

      This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?
