How long should it take for oil pressure to show on the gage on initial engine startup after rebuild?

Re: REBUILT ENGINE STARTUP/OIL PRESSURE
I would suggest you prime it by spinning the oil pump shaft until pressure shows on the guage (should be very soon). You can do this with an adaptor or old distributor and drill. If you do not know anyone with one, check speed or machine shops. To answer your question, it should show pressure in 15-20 seconds. Don H. -

if engine was primed it should only take a couple secondsComment

Re: REBUILT ENGINE STARTUP/OIL PRESSURE
My guess is your low on oil pressure?or drops as the oil heats up?
Do you have the correct rear cam bearing?
Are you using the oil canister/filter or a screw-on filter adapter?Comment

Re: REBUILT ENGINE STARTUP/OIL PRESSURE
Correct rear cam bearing was installed and an original cannister type oil filter installed. The gage is not registering any oil pressure. I'll dissconnect the oil pressure line, blow compressed air through it and reconnect it. The gage worked when it was disconnected (10years ago). I was thinking of leaving the line off at the engine and watching for oil flow?Comment

Re: REBUILT ENGINE STARTUP/OIL PRESSURE
I installed the oil cannister half full. I removed it when I saw no oil pressure on the gage and it was full. Can I assume that means the pump is operating normally? (I primed the pump during engine assembly)Comment

Re: REBUILT ENGINE STARTUP/OIL PRESSURE
Rob: pull distrib, install a priming tool or old dist with gear teeth removed . unhook oil press line, then prime the engine. that'll tell you if pump working although you stated in a previous post that the oil filter canister went from half to full, hence i believe the oil pump is functioning. good luck and from your recent posts and problems you've encountered, sounds like you could use a little luck, mikeComment

Mike,
I've had my share of "murphy's law". The lifters are making no noise at all. I'll check the gage. Thanks again....Comment

Re: REBUILT ENGINE STARTUP/OIL PRESSURE
Every once in awhile the factory oil pressure gauge in my '68 sticks at zero on startup, then pops to normal pressure after a short bit. You might have a similar issue. I bought an inexpensive (Sunpro, I believe) mechanical oil pressure gauge to have around for fresh starts, etc. They come with an assortment of fittings, so it's easy to connect to an engine to check pressure when priming the oiling system, initial startup, etc. I just hook it up, then use a tie wrap to hold it in a safe spot under the hood - hood hinge works well.

re: oil filter type for a '62
Mike, Rob,
Kind of on the same subject... Would you guys change the canister filter to a screw on type when the car is not up for judging? Which filter do you think is better or do they both do an equal quality job? I have a non-origonal 327ci motor in my '62.

For convenience, the spin-on with PF-35 (now, PF-1218) is the only way to go. As far as filtering efficiency goes, the cannister style filters are larger, but the material used in the spin-on type filters is much more efficient, so, overall, they're probably about equal.In Appreciation of John HinckleyComment

Re: Ooops
I was visualizing a Camaro when I made the comment about hooking the gauge to a hood hinge - that wouldn't work well on a Corvette.

Re: It builds fast enough to cover the ceiling.
I can attest that if you forget to tighten the oil pressure fitting on the rear of the engine, it doesn't take long to produce a fountain of oil strong enough to reach the ceiling whereupon the ceiling acts as a nice diffuser that spreads the stream out in such a manner as to cover the car with oil. Moral of the story don't get in a rush and it may help to limit the beer consumption.Comment
