Sanity check before I replace a clutch on my MSM
Pretty sure I have a bad pressure plate (I've read about springs breaking?), but I'm hoping to get a sanity check before I buy a new clutch/flywheel combo. Leaning toward the SM 1.8 organic disc and 13.9# flywheel since there seem to be a lot of complaints about shuddering on the FM happy meal.
Car:
Things I've replaced/installed with no effect:
At this point I'm guessing it's either the clutch or the trans. Any other ideas? Thanks in advance! EDIT: Disc has chunks broken off around the springs, and pilot bearing fell out. Pics in the posts below. EDIT 2: Even before break-in period is complete, new clutch and flywheel fixed everything. |
I think the grinding into reverse may be normal. Can you shift without a clutch smoothly? If not, it sounds like a transmission issue, not clutch.

It's an original clutch, so it probably needs to go anyway, but is there anything I can check/replace on the transmission while it's out? Also forgot: changed out the Redline fluid that had been in ~30k miles for synthetic Motorcraft. |
At this point, you're pretty much going to have to take the trans off regardless, I'd order a clutch either way at 142k miles.
Find a very slight incline, stop, put the car in first and keep the clutch depressed, does the car roll backwards or hold itself? Easy to tell if you're getting proper disengagement that way, in my experience. |
Fluid that is too slick can keep synchros from doing their job well and can make the gears grind sometimes. How in the world did you keep a stock clutch for 142,000 miles?

150K miles on stock clutch checking in. :ugh2:

Duno how it compares to Miatas, but my co-worker has 198k on the stock clutch in his 05 Civic Si.

Your symptoms sound similar to a buddy of mine that broke a pressure plate tang off an ACT plate.
I don't see master cylinder in the list of replaced parts - its a maintenance item that should be replaced with the slave IMHO, they're fairly cheap anyway. FWIW SPM Organic clutch w/12 lb flywheel has been the most pleasurable clutch experience I've had in any car to date. |

haven't bothered with the master, though it's not leaking (yet).

Clutch master usually doesn't visibly leak - just blows fluid past the seals and doesn't build sufficient pressure.

Yes. You can pull the boot back and look for leaks, but a leak really only affects you at a stop with the clutch in. It’ll eventually bleed down and release the clutch. A shift at speed should require little to no clutch disengagement.

Drove that car till it died at 230k miles. Still on a perfectly working original clutch. |
I'm fairly confident the problem here has been identified. In addition to the broken pieces around the springs, the pilot bearing fell out before I even pulled the flywheel off. Guess that makes my decision for me on a new flywheel too.
