I am wondering if it makes somewhat significant difference between a 5w-xx oil and a 20w-xx oil, especially in winter. Pre-oiler addresses the dry running issue upon initial starting up. But it does not address the issue of oil before warming up. My concern may be answered already by many who have said no problems. When I rebuilt my 83.5 engine two months ago at 110k miles I saw no problems in the bottom block. I wonder if I need to pay more attention to oil so that when I need to rebuild it again say at 200k miles I could get away without align borning for the crank. Hope this makes sense, (or not). I will probably toss the block if it needs major work such as align borning. I may be opening another can of worms by saying this. Basically labor cost in the SF Bay Area is so high that I would rather find a way to prevent it from becoming necessary too soon. David
