I got a fresh 555 dart big m going and noticed oil pressure is lower than expected
I have valve spring oilers and remote oil filter with bar/plate style b&m cooler
Engine is in a 3rd gen camaro, so we have filter adapter in the block that has 1/2 npt to -10 outlet running 4 ft of -10 line to cooler mounted at radiator in front of car then 1 ft of line to remote filter housing behind driver headlights basically, thru filter then back to motor thru another 4 ft of -10.
Also from remote filter i have a -6 line takeoff to feed a distribution block near firewall, 4ft away from filter. Distribution block has my oil pressure sender for stock camaro oil gauge and a -4 takeoff to feed the valvespring oilers in the covers.
Two oil pressure sensors. One in the back bellhousing area. One in distribution block off the remote filter housing. Both read about the same
Engine has .0025 rods and .0029 main clearance. It has bushed lifter bores with howards/morel solid roller lifters and it does not appear to drop below or above oil band hole in the bore. Not sure of the exact lifter bore clearance however but they were sized
Melling 10774 std pressure std volume pump
Had lucas 30w break in oil and then moved to 15w40 rotella to see if it changed pressure. It did help hot idle but wot was same
Its idled in the mid 30’s to near 40 cold (80 deg ambient) and hot idled in the 20’s psi at 1000-1100 rpm. At wot up to 6500 its only seeing 43 psi but flat and stable and gets to that pressure immediately on the hit.
It almost seems like i have alot of line and bleed off from the oilers which would drop prssure and the pump is on the bypass spring. Do i just need to swap out to high pressure spring?
