Cam install was pretty easy. However since I put the engine back in i've had some issues. I'm getting a misfire from #3 for no reason, the plugs and wires are brand new and are working properly,(saw the spark plug fire and checked wires with timing light)
The misfire only occurs when the engine is cold though, it mysteriously disappears when the temps get in the normal range. However it runs hot (???)
Autozone temp guage says its reaching 230*, even higher if i let it run long enough - thats scary, but whats puzzling is the temp will steadily drop from that 230* to about 180ish about 5 minutes after shutting off (???) That has to be air in the system, but I know for a fact i purged it and opened the vent tube when filling and eliminated damn near all of the trapped air.
Whats the deal? I pulled the engine to drop in the SC crank and the RPM 216/225 cam with good strong springs. The signs are kinda pointing to HG failure, but the heads werent touched, the engine was running perfectly fine on the 11 month old felpros I put in july 02.
I'm scrating my head on this one, throw me a bone here please? I'm about to try swapping injectors on #3 tomorrow to see if that helps pinpoint the problem.
Anyone here have any ideas? I'm lost on this one.
