Just buttoning up a new head, timing, oil and water pump job.
Where does one hook up a mechanical oil pressure gauge for the initial start?
And what kind of pressure should I expect to see?
I hate to get flamed too hard but I didn't do the petrolium jelly prime thing either, I was thinking about pouring some STP or something down the oil pump PRV orfice (with the spring and ball removed). Any reason why this wouldn't help prime the pump?

Thanks

 

right below the oil filter. around 60 to 70 lbs on cold start up

 

70 lbs? really? sounds a bit high to me.
I'd expect around 30 cold and about 15-20 hot.
I hear there's a pressure relief valve that opens at around 65 psi.

hmmm.. i just put a brand new oem/asian oil pump on my brand new 22re. and i get around that when its cold and the choke is on. but after its warm i get 20lbs at idle, then it fluctuates between there and 50. when warm depending on rpm's

 

also it says in my haynes manual that oil pressure should be.

at idle... 4.3psi minimum

at 3000rpm... 36 to 71 psi

 

I guess I should've said 'at idle' in my post.
so we're about in agreement.
