Looks like my thrust bearings are shot
So I picked up a FD a few weeks ago that was running but not driving. It would start and run, but make noise when pushing the clutch in or putting the car in gear while running.
First thing I did was pull the trans and inspect the clutch area. The flywheel had to go because the previous mechanic stripped all the pressure plate bolts. I installed a new flywheel, bolts, pilot bearing, and after reassembling everything it still made the noise.
So today I pulled off the belts and checked the eccentric shaft. It has a lot of play in and out. So I take it I need to pull the front cover off and replace the thrust bearings? I haven't done that before, any suggestions or other things I should look at?

If you need to do anything else major at the same time (ie, turbos are bad) you may want to consider just pulling the engine out. Not a fun job with it in the bay, you'll have to remove the oil pan as well.

If you have to do anything in the front cover, just pull the engine. I've done a number of jobs under the front cover in FC's, and you're WAY ahead of the game just pulling the engine.
You can leave most of the upper part of the engine together, just pull the oil pan, water pump housing, and front cover.

In the burnout box...

In this game every FD has a low mileage rebuilt engine. There's also plenty of non-qualified knuckle heads out there that do very poor rebuilds. I would suggest bringing the car to a qualified place to be checked out immediately...
FYI if the engine is .0016-.003" endplay you should just be able to hear the endplay and only by trained eye see movement. Watch-out for excessive endplay, it usually means something's terribly wrong. One of my customers made a thread a couple months ago with a "rebuilt engine" that had the thrust washer installed backwards and toasted all the bearings. Check it out...

Sounds like a twin or triple plate clutch
Do you have a twin or triple plate clutch? I have the HKS twin clutch in my FD and it makes a rattling noise when my foot is on the clutch. Since there is no pressure on the plates when the clutch is pressed the plates basically "rattle around" until you release the clutch and the plates are sandwiched together. Just a thought...

Update - I pulled the motor and rebuilt the damaged part of the front stack. One of the bearings was shot because whoever rebuilt the engine installed an extra thrust plate in the wrong location So that part of the car is fixed and running, now to nail down the remaining list to get the car fully streetable.
