oil pressure problems?

[pnamarble]

my t type has 206,000 on it recently hooked up an oil guage and was surprised on a cold start it has 80 psi but when it warms up it only 10 psi is this typical or do i need a new oil pump i hear people put a spacer with bigger gears it does this works or do i have to get a new timing cover??????

My T does the same exact thing. Except mine has 350,000 on it. I haven't worried about it to much though as it has been like this since I bought it three years ago.

Factory oil pressure specs are checked off idle. Minimum spec is 37psi at 2400 rpm
