hello everybody, currently i am replacing the piston rings on the original pistons from a 318 that has been honed out and the new rings seemed to have a significantly larger gap than what is recommended in the manual for a standard size. So thinking they were faulty i got another set but ended up having the same outcome. I'm not sure whether i need bore out the block even though it seems fine or get oversized rings and file them down to spec or if there is a science about piston rings that I'm missing. Any thoughts?
thank you
