i have 91k miles on the car now.. it was great when i got it at 52k miles.. now, after i get up above 50-60mph or so, i have great power.. it seems like just my low-end crapped out.. my clutch rarely slips, but it feels strange.. i used ot be able to chirp my tires or drift around a corner from a stop very easily - and now i can't.. would a bad clutch explain this loss of power? i am still running on the stock clutch at 91k miles, and i drive the car fairly hard every day..
also, i hear that famous "tapping" sound from the engine.. it used to just happen when i was low on oil - but now it happens all of the time.. i heard that the lifters may need to be replaced? what exactly does this involve?
ANY ideas would be VERY much appreciated.. this problem is making me want to sell my M3 =(
Brett, you should be able to tell if its your clutch or not keeping you from chirping the tires in first...Basically, when you give it gas and get off the clutch, is the power going to the road, or is the engine just increasing in rpms as youre standing still. In first, when starting off, do you have to get Off the gas in order to get the clutch to hookup due to too much slippage? Or, does the power go to the road as you expect, only there doesnt seem to be as much of it? A clutch that is slipping badly enough to prevent you from leaving rubber in first will be very obvious to you...So, based on this, I suspect its something else.
