well heres the deal. my dad put in my jdm engine about 12k miles ago, using all toyota clutch stuff, either resurfaced or new. i dont drive my car too hard, just the way its meant to be driven occaisonally. this morning my clutch action was great, but on the way home, i did a hard shift into 2nd at 5.5 rpm and since then my clutch has a very rapid repeated tapping on it at all times. as soon as the engine turns off of course, the action feels normal. while driving after it happened, i dont think i noticed slipping, just a stunted notchy feeling clutch and it seems to take more rpm to engage it smoothly, ( at 1.5rpm it now jerks engaging) whats going on guys, any ideas, i dont know much about this stuff. it a bad part of the flywheel, or a throw out bearing maybe. please help me....
