No oil pressure

Hello

Fired up my Healey engine for the first time today, however there is no oil pressure. The engine was rebuilt by the previous owner and has not been strarted since, and has probably been sitting for 4-5 years since the rebuild. Oil is being pumped however, as the oil filter was full, and oil is coming out of the rockers. I removed the oil pressure pipe from the gauge to ensure there was no airlock and ran the engine briefly to see if any oil came out but nothing, and no pressure on my finger when I placed it over the pipe. Any body got any idea what is going on?

Thanks

Myles

I would remove the flex oil line and check for blockage.
 
I agree with Patrick, in particular check the fitting in the block that the flex line screws into - this fitting has a very small hole for oil to flow thru. I don't remember exactly but I think the hole is only 1/16" or less. Pull this fitting and make sure it's not plugged (wouldn't take much to plug it).

As I understand it, the reason for the small hole is twofold: One, it acts as a damper smoothing out fluctuations in pressure so the gage needle isn't jumping around. Two, if the flex line or pipe breaks, the volume of oil that would leak out is greatly reduced from what it would be with a normal fitting. An old racer trick I was shown years ago is to bore out the hole a bit to get the gage to have a more rapid response to pressure fluctuations.
 
Thanks. Took off the adaptor on the block and cleaned it and now have 60 psi on the gauge.
