Thanks for the helpful info on this subject as it stands looks like babbot for me. My car doesn't have a filtration system so at this point I'm sending my crank out to be reground to round and polished then heading to a babbot shop. I will check in the discussion boards for a post thanks again you guys for the replies. FRED 1930 Dodge DH 4dr Sedan, inherited from my grandfather Amherst NS Can.
