Okay, fired the new motor today... Oil pressure when priming with drill was about 50 lbs. Fired right up, started breaking in the cam, pressure started at ~65-70. Temp raised to about 190-200 during break-in oil pressure dropped to about 45-50. After breaking in cam, set the motor to regular idle, oil pressure dropped to 25, then about 10. No noises.
Book says idle at 2500 rpm should be at least 37psi, mine goes up to about 50. RPM oil pressure is good, idle pressure is low.
Oil is Castrol 10w30
New stock oil pump gears, melling booster plate. Stock front cover, oil mods done (1/2" holes, ported, etc) Yellow spring (60lbs) Regular small filter, plus custom oil saver/remote oil filter. -6 from brass adapter on front of block to remote filter, -4 to turbo, -10 drain to pan.
Questions:
1. If I change oil to 10w40 or 20w50, is this just band-aiding a problem?
2. Will the extra filter/lines lower the idle oil pressure?
3. When I made all the new oil lines, I could not find correct adapters to connect the AN lines to the stock brass block, so I found a similar one with the correct threads for the adapters. I asked when fabbing this stuff, and now I will ask again: Is there anything in the stock brass block that has an orifice as to limit oil pressure to turbo/ gauge sender? (directs 70% to motor, 30% to sender/turbo?)
Any and all help would be greatly appreciated.
