Ok i managed to drop the crank on my AEB so am sourcing an small port APU engine to replace it ( Good used price) and cant afford to build one at the mo.

And i read somewhere that unless i have a BAT the port size on the AEB is more likely to loose me torque etc anyway

The point of the post is this, i whipped the head off to seel it on and found number 4 piston with these "clean" marks on it. The bits are kinda pitted but this is the only piston like it.

Any one know why? As detonation would be more central wouldnt it?
