Guys, I need some advice, a couple if weekends ago I was out wheeling and hit a tree stump which put a sizable dent in the oil pan. I drained the oil and using a slide hammer and a welded nut I tried to remove most of the dent. I then filled up with my normal 20w50 and some stop smoke additive (burns a little oil) and I noticed that the oil pressure would be normal at idle but when you accelerated the pressure would drop off and when the gas pedal was released the oil pressure returned to normal. My thought was the dent had damaged the intake or the dent maybe was still blocking the pickup. I thus removed the oil pan, and saw no damage to the intake pipe work and the strainer looked perfect. So I repaired the dent and reinstalled the oil pan. I've still got the same issue. Can anybody shed any light on a possible cause for this. Was thinking a oil filter issue or oil pressure release valve or cracked intake pipe allowing air to be drawn in?
Note my oil pressure would normally be:
60 PSI cold
40 PSI hot normal running rpm
20 psi idle
