1970 Duster AlterKtion, 4 Link, LS/T56/Turbo and Minitub
Welp, got the motor apart this weekend and found the 2 broken pistons. Did a leakdown test first and 7 and 5 both had about 60% leak down, so I figured it was going to be the same thing as before and it was.
Cylinder 7
Cylinder 5
Disassembly
Aaaanndd the wall trophies
New pistons should be here this week. Hopefully this time around with the new tune changing the dwell I wont have this issue anymore. Went back and checked the data log and never built more than like 12psi of boost. So I can't imagine it was boost that hurt the pistons.
