I raced this past weekend at Blackhawk Farms with VSCDA in my first open wheel event and the first time the 1972 Merlyn 20A has seen a track in 23 years. What a blast! Stayed safe-ran well-got faster each session. Final race-started 18th of 30 and finished 12th, which was 5th in class. A few questions that I was seeking answers all weekend.
What is expected of low oil pressure when you are idling as you come off track? I saw 5-10 psi, but at race revs-had 50-60psi and could rev it and get 10-15 while coming off track. I am running an oil cooler and Valvoline SR1 20/50 wt I am going to replace the gauge and the SS line that serves it just in case too.
What oil weight? Some say 20/50 and others say 30 wt or 10/30?
We pulled the pan drain plug, saw no metal at all-the 1/2 qt of oil we checked had no metal in it at all-I am going to pull and cut the oil filter to check as well.
Is there a secret in replacing the scavenge oil line from the pan to the Pace pump? I should-but that thing is next to impossible to change-the Pegasus one is stiff-I get it, but how do you get it to fit both the pan fitting and the oil pump fitting?
What is the secret to keep the valve cover from leaking too?
Anything else I should do to make sure I am ok to race and have no engine damage?
Help..I want to race at Indy in August-but not if I have an engine issue.
