I overhauled a 1960's 4020 6 cyl., 370 or thereabouts cu. in., LP inframe. Had never done it before. Was wet sleeved and reason for the OH mainly was concern over oil coming out of weep ports on the side of the block.....little holes that tell you that either the cooling Oring or oil Oring has failed and is leaking.

Sadly though all his efforts seemed to be a waste of time and money as he still couldn''t get the temperamental old thing to run correctly!! If i said that this was a little frustrating for him that would be "conservative" in fact the problem had reduce
