Delayed oil pressure on start up

[QWIKWE4]

Just got the motor together now for about a month. Everytime I start the car it takes awhile to build up oil pressure but when it does come up it's good.

Using a HV timing cover.

Also the oil pressure seems to be pretty high. I got the lightest relief valve spring in it and when it's warm oil pressure is about 45-50 psi and when I get on it, it maxes out at ~70 psi.

Is that too much?

More than most & just wears out cam sensor gears faster. Important thing is it rises 10lbs for every 1000 rpm. What weight oil? Maybe go with some thinner oil?

I'm using Valvoline VR-1 20-50. I guess I could try a 5w-30 oil

Might check your oil filter. Some of them do not have an anti drain back feature. I do not remember which one has it and which one does not but I am sure someone will chime in to give the filter numbers to use. Also did you adjust the roller lifters correctly. If you have too much pre load it will drain the lifter.

what kind of a gauge? if it's a mechanical gauge, there can be a bit of a delay in seeing oil pressure until the line fills with oil.

It's an electric guage. I think I'll try finding a filter with an anti drain back valve first.

Wix 51036 has one along with coil spring, Most have flat metal
