1990 ZR-1

Bought a 1990 ZR1 with 81,000 on it about a year ago. HVAC needs 134A, a couple of switches and the door locks dont work. Make sure the fluid levels, what they look like. I of course checked the fluids on mine and they read correct. I was on here last week because I discovered the oil dipstick was not the factory original. I changed the oil and got about 6 quarts out. Thats when I started looking for the answer of 'What the Hell?', and found the dipstick was out of something, I dont know what. The car had had the oil changed at a 'quicklube',as the oil drain bolt and filter were torqued to about 5682 ft lbs. and they of course put the required 5 + quarts you get with a regular oil change. Getting the dash redone(my tachometer didnt work) will take months, be warned. I am replacing the Bose as it does not work. My stuff is normal stuff that fails on a 30 year old car that the previous owner didnt know or care what he had. I knew most of this stuff when I bought it. It was at a specialty dealer who was going to repair all these things and sold to me kind of cheap "as is". As far as mechanical, it had a small vacuum leak found at my local 'vette performance shop. In short, some things may not work, but the LT5 is a great motor on a lot of respects. Run good, fluids good, put it on a rack and look for damage, no rattles, you probably have a great car which will be a lot of fun to drive. I have had a couple of the mechanics that test drove it at the shop tell me it doesnt drive like most any other Corvette. I also have an 85 Corvette. The C4 ZR1 is kind of a car unto itself.
