Morning Members,
Ran with VDCA @ Atlanta this past weekend. If you've never run with
them you had better get on the schedule as it the best vintage group
around!! Lots of fun and lots of track time.
Anyway back to my query for you all. On the 2nd practice session I
thought I noticed the oil pressure drop suddenly to 20 or so PSI.
Started watching it and saw it float from 60 to 40 down to 20 back to 60
etc etc. Got to the pits ASAP. We installed a test gauge and had 0 PSI.
tried a lot of stuff but eventually dropped the pan and yes you guesses
it the pick up had split at the pipe threads where the jam nut flat side
is facing the bottom of the oil pan. So got lucky and found some folks
with lots of tools and got the broken threads out of the aluminum
housing and had enough threads to reinstall it. VOILA all of the sudden
I had 80 PSI at speed vs.. the original 60 PSI. So I am guessing it's
been cracked and sucking some air for a while now. Then this weekend it
finally opened up enough to drop pressure and give ole dummy me enough
time to see it happen and get in the pits to save my almost new engine.
This pick up had been extended approx 2 inches as I have a stock pan
that has been deepened and baffled.
Again I digress what is the best solution to make a new pick up out of
that isn't so thin that it can crack at the threads again. I like
working on these old piles of parts, but NOT at the track. What pan do a
lot of you racers run, is a deep sump even necessary?? I had it and just
reused it etc.
Thanks for any help you have!!
