Ok, so the heat guage on my 97z28 apparently was stuck on regular operating temperatures while it overheated, and looks to have at the very least blown a head gasket and/or warped/cracked one or both of the heads.

I first noticed it when the engine would bog under accelleration, and steadily got worse. At first I thought it was the opti, since I've heard all sorts of horror stories. It finally got really bad and wouldn't idle steadily, then started idling at 2000rpm in neutral. I shecked the exhaust and there is a LOT of moisture in it (visible water on the ground behind the car).

So, I'm trying to figure out what to do, and plan for it. Should I just get a whole new motor, or just replace the heads(I'd like to get some better ones anyway)?

I'm just worried that if I only replace the heads the opti might still be messed up, and I'd like to avoid having to pay someone to pull it apart to diagnose it if I don't have to.

Anyway, thanks for the help!

i would find out why it happend in the first place before i put any money into it.

 

Are you SURE it's screwed? Have you checked your oil for water yet? Lots of moisture from your exhaust can a number of things. Could the puddles behind your car have been gas? If you don't find water in your oil, and your not burning coolant/throwing white smoke you might just be a good candidate for being in Opti-Hell (or other electrical problems). Here's hoping
