Clutch Slipping
1997 993, 6sp, 100K miles. Purchased in 2010 with 70K Miles. Records show clutch was replaced at 35K. At least half of last 30K miles were "in-town" (i.e., not long highway rides).
|
Given 65K miles on the clutch and the fact that it is already slipping, I'd say chances are real strong that it's time for a new one.
|
Agreed. Sounds like it's time for a new clutch and the rest of the "while you're in there" issues you have.
2 posts in 8 years, you must be the quiet type! |
Unless someone really abused the clutch, my previous car now has over 186,000 miles on it, with the factory installed clutch. Almost all of it city driving.
Any oil at the engine-transmission mating surface at the bottom? |
With a slipping clutch any fix will involve an internal inspection of the clutch and in most cases it will involve replacing some or all of the clutch package components.
On the upside, one need not "drop" the engine on a 993 to remove the transmission and service the clutch, flywheel or power steering belt saving a lot of labor charges at most shops. Andy |
Yes, there is definitely oil in that area. Need to see from where else it may be coming from (pretty sure there is some leaking at the timing cover).
That being said, is there a way to diagnose this situation without tear down (i.e., I know I should bleed the clutch system and replace gaskets, but if I don't need a clutch, I really don't want to buy one). I'm not saying I don't trust a shop, but it's real money to me and I'd sure like to know how to verify --- preferably before I head in. |
Bleed it all you want, but nothing will change. When you're going down the road, the clutch linkage (including all of the hydraulics) is completely out of the picture - the clutch is as engaged as it can be. The problem lies inside the bellhousing: worn disk, failed pressure plate springs, and/or oil on the clutch. You don't have much choice other than to pull the trans and look.
|
If there's oil, chances are a motor drop is in order to address a potentially leaking rear main seal.
Yeah, I know you dont want to hear that... |
Ok, sold; sounds like a tear-down to get to the bottom of it.
Many thanks for everyone's time in looking and reviewing. |
Keep us posted on the cost, etc...thanks...

I am dubious it needs a clutch. It'd be amazing if the disc is worn down to the rivets after 65K miles of around-town driving. 993 clutches are robust. The disc in mine had plenty of meat left when I did the clutch at 115K. If it's slipping in 3rd, then it's slipping even more in 1st and 2nd. You should be getting slippage in all the lower gears, and it should be unmistakable.

Also, one doesn't need to abuse a clutch to have it go south after only 65K miles. Lots of city driving in a hilly town like San Fran will wear out a clutch much faster than, say, highway miles only in the flatlands of the mid-west :cheers: |
