I am really having a hard time understanding how too much oil pressure
will cause valves to open at the wrong time..I used to switch to the
high volume/high pressure oil pumps whenever I did a rebuild. Like on
the ol chev 350 - normal oil pressure around 20psi idle and 40 cruise.
HiPo pump - about 40psi idle and 65-70 cruise. That is what I currently
have on my boat. Of course, the higher volume/pressure will find any
leaks faster too. Any insight?
