ami reading this correctly? the OP saying you were racing at half throttle? please tell me i read that wrong. i wont flame you for blowing up your motor cause your not making up excuses, but im sure you'll be better about running the car hard when you know it cant handle. good luck with your new build

no i usually run it wot open but this particular race i didnt give it all the way cuz the evo was slow to begin with and i knew i didnt have enough fuel up top so i just gave it a little more than half and still had enough to run away from him

These are the four codes that I pulled off the computer,
I pulled the plugs to do a compression test, and yeah number one isn't looking so hot, and the compression test confirmed it, cylinder 1, 0psi, cylinders 2-4, all around 180psi
pulled the couple from the intake to the Throttle body, and it had a little oil inside it, than pulled the supercharger, all clean on the inside, and still looks new
Looked down in the intake manifold, and their is some oil sitting down their, tomorrow I'll get his intake and head off and see just how bad number one really is, I looked down their a bit and from what I could see it has some oil built up inside it, and the other three are a little drier, but we will see tomorrow.

They were autolite xp 3923, so yeah, it could be the sleeve, we'll know tomorrow when I get the head off, he's already got a nice built engine he's talking to a guy about, so he is really just waiting on me to figure out the route he's gonna go

Got the head off, carstedt was able to get off work early and helped finish the job, all in all, the sleeve looks fixable, but gonna take it to the machine shop and have them check it out, their dont seem like their is a hole, the water jacket is still holding the water back, just looks like when the piston melted it got all over the sleeve

Yeah, I'm also thinking their was a little fueling issue too, and it did blow the seal on the head gasket a little too, so head studs, New fuel pump, and a rewire is going in too as well as what he does to the internals, gonna work on pulling the block this weekend and maybe get the block to the machine shop for him while he's on vacation. So we should be looking at a nice little monster when she's all back together

if you think the plug caused that then you are way off that piston is melted fuel got past the top ring then it was ignited fractured the piston when the piston fractures it starts melting because you expose the part of the piston that isent hardend so each time the fuel ignites a little more melts away all the shiney rough spots is from the strap of the plug being beat around inside of the cylnder

Lol ^: u seriosuly are taking what I'm saying wrong... I said fuel played a major part but as did the plug...... I know what I'm talking about lol no need to chant somthing ...... Autolites don't Sparta correctly which is a known issue with themso there for cylinder wash. Which then causes issue above lol.....
Cylinder wash with spark= boom....
Cylinder wash with spark= boom....
