cold idle it reaches around 80psi, drops back to around 40psi hot idle and to be honest i'm not sure at 2k hot as i've never really taken much notice of it there but at 3-3.5k it's around 65-70psi

gauge hit 45psi yesterday just spinning it up on the drill with a new battery. if the gasket between the pick up pipe and pump was at fault would i still get good pressure but get air in the oil? i've just never seen so much air in oil before! noticed before i took it apart when the engine is running the oil ends up looking almost milky in the head due to the amount of tiny air bubbles in the oil but i've never seen that before on other cars!
