LJ and tz,
I believe the problem is the pilot bearing (as I said), not the throwout bearing. Tz's description of the noise and "Kick" is consistent with a seized pilot and not consistent with a worn or seized throwout (a.k.a. release) bearing. A bad throwout bearing mostly just makes noise when you step on the clutch pedal (no kick). Of course you can't fix either of those without removing the entire clutch assembly. The idea that you just have a clutch disc rusted onto the clutch shaft splines has some merit. That could cause the kick but probably not the metallic noise. You've nothing to lose (except a little time) by pulling out the clutch shaft, cleaning and lubing it and then seeing if the symptoms are gone. Tz If you do end up pulling the clutch assembly here's a few tips since you haven't done this before: The biggest problem for first timers is not installing the tool sufficiently or using too thin of a tool. If the cover spring is inadequately depressed you won't create enough clearance to slip the clutch assembly out and that is very frustrating and requires tedious backtracking so focus on that task. The tool can be formed from any number of common things including #6 solid copper wire, an old lawn mower throttle cable housing or a bucket handle. It should be about 0.140" diameter. Since your hydraulics are working well it's just a matter of having someone mash the clutch pedal and hold it while you insert the tool. Pump up the pedal if that creates more movement of the clutch slave and throwout bearing and cram the tool up under the fingers deliberately so that there is little or no return of the spring when the pedal is released. Don't unbolt any clutch components until you have the tool fully installed. Of course it's possible that you actually have two or more defective parts like a rusty clutch shaft and worn throwout bearing so that you get one symptom from each but if that's the case you'll have to pull the assembly out anyway, it's just a question of how many bad parts there are. The common practice is when the assembly comes out we do the rear main crankshaft seal, pilot bearing, surface the flywheel (if needed), replace the disc, cover, throwout bearing, slave and clutch shaft seal and then there's no need to go back in there for a long time. Few things suck more than replacing a bad throwout bearing and then having the clutch shaft or main seal start leaking (and they will). To save expense the first part to re-use would be the cover unless you have symptoms consistent with a bad cover (doesn't seem like that). The other stuff is fairly cheap. Good luck
