I recently rebuilt my Farmall C engine a few months ago and just today I got a chance to pull hard with it.I noticed the oil pressure drops to 0 at idle when hot and towards the low side at wide open throttle when warm,however it maxes out the gauge when cold and it has a new IH gauge in it.It does not knock at all and runs great.I had disassembled the pump and screen during the rebuild and polished the cover as I had read they can get grooved which it was but only small grooves maybe a few thousands deep.I had to use RTV to seal the cover,could this be an issue,not having used a gasket?
