Oil leak, between flywheel housing and block

[Signature620]

Scotch pads will absolutely get them ready to refit, no problems.

I prefer to sand them as most of them have serious fretting. It leaves a nice, uniform finish without the excessive time and material loss of having the housings machined.

I use the same practice for all flat gasket surfaces of exh manifolds, front and rear housings, thermostat housings, intake manifolds, etc. Consider it a gentlemanly alternative to those 2" buff wheels people like to use.
