alright so my friend has a f22b dual cam if yoru not familiar in his accord and he blew a hole in the number one piston, needs to be rebuilt but we arnt sure if they have nickel coated sleeves....is it just the h series that is like that or is it the f series to. if anyone that was sure or had any idea please help us out..thanks

 

the f22's have iron sleeves so they can be rebuilt. h22 sleeves are fiber reinforced metal not nickel coated though.
