theres a theory floating around that if you use the ls6 style crossover on the front and back youll help cool that part of the motor better
that would also make sense why you were denotating before the meth. what was your target A/F? what was actual A/F? what Tstat you running? by any chance would you have a weak injector for that cylinder?
his theory makes a lot of sense as for the heating up and expanding but in order to do that it would of been extremely hot. not to many ppl run .040 that would net you a custom piston...in that case a new block might be cheaper....figure price of machine work for bore and cost of pistons vs the cost of block and boring

Thermostat is a 180*. I won't know injector status until I have them flow tested. The LS6 crossover would be a worthwhile investment if it will help. I'll see if I can find one over on tech.
Rex has been looking through this thread, hopefully he can post up some of the clearances if he remembers them or has them written down somewhere.

Well after finding out about all this crap I'm pretty bummed out again. Thanks for all the kind words everyone. I really am hoping for the best but it just seems like I keep getting shafted over and over again. Hopefully the tables will start to turn the opposite direction one of the days.
Right now I'm looking at another $1400 or so for the new parts, then add in the cost of fittings and adapters for the new fuel rails, then the cost of parts and labor to fix the engine, which is up in the air depending on how bad the damage is. I was just getting to the point to where my finances were starting to look up again. ****. This is a great graduation present. The only upside is that I should hopefully be getting a raise here shortly....not sure how much though.
