Okay so i’m pretty new to asking question on forums. But i need Help from the OG honda guys.

Build List:
B16 Sleeved Bored to 84MM
Arias Pistons
Eagle Rods
Blocked oil squirters
ACL Race oil Pump
ACL bearings
Fully built head (Springs, retainers, valves, Skunk 2 tuner 2 cams)
Pulsar Gt3482 gen 2 turbo

So now my question is when i start my car. My oil pressure is high obv due to cold oil. when it warms up it sits around 60 ish psi a bit high, not sure. After doing breakin process sitting at 3k for 3 minutes . With MOTUL 10w-40. The oil pressure reaches over 100psi. My motor was put together by a very reliable local shop. Now idk if they oil pressure is way to high because of to thick of oil or bad oil pump from ACL. There doesn’t seem like too much crank pressure cause my dipstick doesn’t pop out. Not sure if that’s relevant. What yall think? Should i change my oil pump or is there a valve adjustment on the oil pump? or thinner oil?

Sorry if this has been asked. Anything would be helpful. I apologize in advance.

 

What was the reason that you chose to run 10w-40 viscosity oil in the first place ? Thinner oils will drop the pressures slightly.

 

As per the machine shop they told me to use thicker oil cause of loser bearing clearances. I’m really thinking about just putting 10w-30 instead. Would it drastically lower the pressure? Fyi this is also the second start of this motor. Also haven’t physically put it in gear and drive it.

 

Let the oil warm up more before you drive it. 40w is prob best still. But you have to be mindful. Fully heatsoaked you will prob see 20-25 psi idle and 60-80psi full load. If you do laps, prob 50s or less under load.

Idle till it warms enough that pressures drop to 40s on idle, then you should be fine.

 

I understand about warming the car up. I usually don’t mess with the car until it’s fully warmed up. Oil pressure full warmed up just idling is 50psi. Then once i revved motor to 3k and held it there. The oil pressure climbs to like 70..80…90.. Once i let off the gas it drops down to 60psi then slowly ticks up..

 

Whats your ambient temps like? Its still cold by me. You won't see fully heatsoaked till you go on a decent drive on an 80°+ day or you do laps at the race track

 

I did this when it was about 40ish to 50 degrees out. But that makes a difference even when the car is fully warmed up? Temp gauge showed 195 when this was happening.
