I have a 93 sc300 manual with about 190,000mi on it and when go to release the clutch on higher revs it smells like its on fire and i can smell it from inside and outside the car and i cant tell what it is CAT? Clutch plate? Please help

 

ok Im bringing this one up since it never got an answer. First off somehow I think I now own this car, as I find an illinois registration in my pile of papers, second off, once the car gets hot, the clutch slips at higher revs. Now I had to replace the rear main, main housing seal and properly replace and torque the flywheel bolts cause the previous owner or shop didn't do it properly and they were loose as well as leaking oil. The exhaust system was coated with a light mist of oil on the outside as well as in the shield. All was cleaned and put back together. Still the clutch slips when the car gets up to temp on pulls. As of right now there is no leaks under the car, could the flywheel at this point be junk? Or should I look to something else on the car causing the issue?
Any input is appreciated, as I would like to drive this thing more than 3 miles at a time.

 

ok not his car but same issue. user hasn't been on here for a while.
