oil pressure

[oldgasser]

Got a brand new 440 all new internals .055 over ,new oil pump , cam, bearings , crank turned all new runs great ! My question is on start up it takes 1-2 seconds for oil pressure to come up and sits at 65 + lbs . cold then holds 45-50 lbs at idle after warmed up , do I have any cause for concern ?

I wouldnt think it's an issue.

do you have a oil filter with anti-drainback valving..? if not, get one...

As stated above and where is the filter, on the pump or is it relocated

why would you be concerned?...thats fantastic oil pressure. its probably taking 1 or 2 seconds to register on the gauge....mine does that and i dont have any issues! are you using a mechanical oil pressure gauge or electric? if mechanical...you need to bleed the air out of the line!

My 440 does a similar trick but it sits for many days to weeks at a time. Also my old Ford truck had this problem and I narrowed down that it started after my last oil change. I suspected the filter and I was right. Put on a new filter and no more oil light staying on for a long time. When I cut the old filter open to investigate I found the bypass valve not sealing.

Hmmm, I may change the filter on my 440 and see if it makes a difference.
