hey shoota, stripped that A15 last night too... cant see much wrong with it at all... Bores are still in good condition.
Havnt removed pistons or crank yet, was sposed to do that tonight but the steering box brace turned up hahaha.
But from looking at the rods and crank from underneath theres no signs of anything bad... no discolouration or anything so hopefully all is well... gonna strip it completely, and send the block away to get cleaned, tested, and prob bored 20thou... rebuild and do a EFI conversion.
