BURNT VALVES

[TNstanggurl]

Well we are doing the pi headswap and we found out that all 8 of the valves are burnt!They were all red cherry red!The night that i got my car it freakin hauled ass,like it had never been hossed on..Then we noticed after all of the hossin we did that night it was runnin really hot.It was like almost on the A.So the next day we replaced the thermostat and did a radiator flush and it still ran hot.After that we decided put a switch on the fan.It never got hot again until we gave it hell or ran the air conditioner.Hopefully after all of this we will see a drastic difference with the comp 270's.What do you guys think?

Mine runs hot too. I really began to wrry when it started overheating this summer when I ran the AC. I flushed (twice), replaced the thermostat and put on a new water pump. It has gotten better but still gets pretty warm. Post results if you see a difference after replacing the valves.

Hey,when valves are burnt you lose compression.The higher the compression the more power.Does yours feel like it is slower?Thats how mine felt.It was still pretty quick but not fast like the night i bought it.Everybody is saying that i should notice a tremendous diference.Do you have a 96-98 model?If so you should go with the pi swap,and you can find out the problem.My boyfreind is out there right now putting evrything on,so he should be done tomorrow afternoon.I will let yuou know then.
thanx,

Burnt valves generally indicate a lean condition..........what did the electrodes on the plugs look like? Change your fuel filter while you are at it.
