remove the engine. get yourself some "threebond" from any mercedes benz or fuso truck centre. around $35 a tube. its the bees knees of selants. pm me if you can't find any
it will never leak
cheers stu that was the aim for compression. i know the crank/rods are gonna be fine for 12psi. more that this i not sure the endurotec or the other more expensive pistons will last.
my machinist also said that 7k pistons sit 2mm lower in the bore. even less compression? LOL
