Hi all
I have a 2004 KJ, 3.7l, manual transmission, with about 160k miles. I've recently developed what seems to be a dragging clutch which, if confirmed, would be only 8k miles after a new clutch and clutch slave.
(That's not the first replacement for either -- it's a long and sad story. FWIW, in the most recent case, I went on an unusually high RPM / hilly drive, then there was a brief burning smell while driving, then it wouldn't go into gear when stopped at the next light. The clutch feel and bite point are still normal. It engages gear fine with any forward speed, but sometimes not while stationary and especially after driving it hard. The level of fluid in the master reservoir looks good.)
I was trying to think of reasons why clutch stuff might keep breaking so frequently. It occurred to me that there is nothing between the external clutch slave and the driver side cat, and they're really close together. If the cat is running at 1200F and DOT3 boils at 400F, it would almost be surprising if that didn't cause problems.
My question is: is there supposed to be a heat shield protecting the clutch slave? I don't have another manual liberty to look under and I can't remember whether there used to be one. It's *very* believable that if there was one but it was in poor shape, some highly qualified mechanic decided to throw it away. I can't find any reference in the manual, but they don't always cover stuff like that.
(Apologies if this is a red herring -- trying to think of everything before dropping $$ on yet another clutch.)
