About 5k miles ago she stated making a high pitch squeal when disengaging the clutch if I tried to give it gas right away. It only lasted until the gears engaged. It did it when shifting between all gears, but the worst from 1st to 2nd. Sometimes it would do it even if I matched rpms and double clutched. A lot less frequent if I shifted carefully though. Squealed on almost every engine brake and downshift unless I was at very low rpms. No other clutch related issues, no slipping, but the clutch is of unknown age and the pilot bearing whines sometimes so I just figured I'd replace it. I also got a new tranny shaft bearing, and have just been waiting to put them all in, driving it carefully.
That was my problem, here is my current situation and question. I drove it down to Florida from Colorado just after the squeal started happening, and finally got around to a tuneup yesterday. Bumped my timing up to ~20--I had been getting pinging on the way down to Florida so I retarded it a little--leaned out the weber, dropped the idle, and seafoamed the carb/pcv vacuum hose. Lots of smoke from the seafoam, obviously running a ton better as to be expected.
Now, today on my drive to work, no squeal between 1st and second, no squeal when I engine brake. No squeal. Is there something that would squeal when engaging gears that the seafoam would have fixed?!? I'm so baffled, but so pleased that it's gone. Just wondering if someone has any opinion on what it could've been?
