camshafted

I have the swap stated in the title and whenever the rpm' drop bellow 1k especially when the car is really warm the oil light comes on. Oil level is good I know for sure. I do not believe it is the sensor because it is not erratically coming on as if it was grounding out or something. It comes on specifically when I am bellow 1k. Whether idling or shifting because my 8lb flywheel makes it drop lower in the rpm range when I push the clutch in. Would the fact that I had to block off an oil port on the head cause it to not get enough oil pressure? I didn't see anyone else having that problem when I was doing my research...

92 Prelude H23 head and F22 block.

Thanks!

which port did you block off?

did you remove the balance shafts?

I did not take out any balance shafts. and I blocked the port you are supose to block off. It is just a return line I found out so it shouldnt mess with any oil pressure.

I figured out it is due to a loose bearing. I figured this out by adding lucas oil additive to my oil. it quited the ticking down which diagnoses the problem. This also explains the low oil pressure...

It really blows because I just finished building this motor and putting it in... Less than 500 miles on it...
