I just replaced broken oil pan gasket on my 95 240sx and my clutch still slips here and there. I originally thought the clutch was the problem until I got under there and saw oil leaking everywhere. So I put in a new oil pan gasket and figured the oil would burn off of the clutch as I drove it.... well it's not working out like that ha hah. So now I ordered a clutch kit and need to get tools for the job. :P
basic socket and wrenches. Need a torque wrench and the kit should have a clutch alignment tool in it.
A hoist(2 post) would really help, and a transmission jack. Probably a good idea to get a flywheel grinder as well.
