The engine is open.
Catastrophic failure of headgasket.
No sign of fuel/bore wash. Honing pattern is still intact, as suspected. Piston rings installed correctly and all still in working condition. No rings have failed.
Block is cracked between cylinders 4 and 5. Sleeves cracked in all cylinders. Caused due to overheating and detonation between cylinders. I suspect headgasket was the start of this. The gentleman who opened the engine suspects that the sleeves installed were done incorrectly and were not of proper material needed for boosted application. Peter, whose responsibility it was to build this engine knew very well what I was going to do with it, so if inferior sleeves were installed, then he needs to explain why. Another question is whether a torque plate was used by JB engineering when they bored and sleeved this block. So whether a torque plate was used or not, I honestly cannot say yes or no, this is something Peter will need to answer. What Sleeves were used? I was under the impression that a special hard material would be used. I recall the name Delron being mentioned. But these are not Delron sleeves. If this is truly the cause for the failure, then I have nothing more to say here.
Cylinders are suspected to be warped as there is sever piston slap. Again due to sleeve failure. All 6 pistons are damaged. This was the source of the sound we heard in the engine.
Bearings seem fine. Crank is being inspected. Rods seem fine.
Bottom line, I need a new block and 6 new pistons. They will be checking my cylinder head to see if any damage found there.
Tune file can be vindicated as this is a mechanical failure. Peter I think you owe Burgy and apology.
Cheers guys.
