Fellow Imperialists, I have two problems with my 413. First, the block is porous. The block was leaking coolant between the freeze plugs. After two treatments of engine block sealer, it appears to have stopped leaking. Second, I have a problem with blow-by. I do not have PCV yet, but I hope to add it soon. Thin smoke is coming from the oil filler cap and draft tube, but I don’t see any smoke coming out the tailpipe). The engine burns a quart of oil almost every 50 miles. I have tried using Restore and it does seem to be improving the blow-by. With the problems I have, should the original engine be rebuilt, or should I start looking for a replacement engine?
