okay running into some probs. i got a 2000 z24 with 75K miles. i've always kept careful maintenance of fluid levels, oil changes every 3K miles, spark plugs, etc. very recently, i've been encountering a problem where the engine has been making this chirping/clicking noise at approximately 3500 rpms. can't be a good thing. and now it seems to be sucking down oil and the engine coolant is leaking somewhere. needless to say, its off the road until i can get it to a mechanic, and the soonest he can get me in is this tuesday. any ideas on the problem could be so i have an idea of what to expect/ pay out? i'd appreciate any help.
