my friend got problem while he was buy new piston for his m40 engine and the piston size has over the top of the engine block about 5mm.
so how to solve this problem? he then buy e30 m40 conrod but the shop send 19 cm but it is same with his old conrod.
so I'm curious need to know the real size from top to down of both conrod and both piston.
any info will be very appreciate.
thank you
