Default Re: Question about connecting rod polishing

Be sure NOT to polish the piston skirts, the roughness/machined ribs is what holds the oil there....and dont do the intake ports either...port them, port match them, raise the floor, etc etc, but the slight roughness creates minutte turbulance right at the surface which keeps your fuel in suspension. Polished intake ports can lead to fuel dropping out of you A/F mixture on the slow side of the port....this means poor performance and possible washed out rings in severe cases.
