well its getting time to swap out my clutch. its got 154K original miles circa 1993. anyways, over the last few days ive had intermittent slippage. 5th gear hiway, pedal to the floor the bitch slips. it doesnt matter if the car is cold, been running hard or light. sometimes it slips in other gears. it almost always grips but ocassionally it will slip for a few minutes. now i also have a rear main seal leak, which has been leaking since i bought the car apparently..... last august. all ive done so far is give the clutch cable a bit more play so the clutch engages a little close to the floor. that seems to have helped a bit. ill take any suggestions. the car in reference is my 93 mirage es 1.5.
