Another low oil pressure (new motor) thread
I just built a Ls2 403 c.i and I am having trouble with oil pressure. around 12psi
Things i have checked are
1. dumbell in the rear
2. oil galley plug in the front
3. has new rear cover plate.
Motor has a brand new melling HP pump.
My question is. I am running a autokraft oil pan and it came with a oil filter mount in factory location.
I plugged the two ports on the side of the oil filter block instead of running the factory bypass plate cause i have a very tight clearance issue..
could this be my issue?

As you can see from the oil path on the LS1 you just starved your top end, bearings, lifters and rockers for oil for 20 min, not good at all!
I would definately take it back apart and see what damage you caused.

You may have some damage. Put the correct cover on and see what you got.
No matter thought it’s not good at all and it definitely warrants a teardown to check for damage.
also noticed a small drizzle out of the pushrod tube.. It was actually very quiet and had no engine knock or lifter noise and was quite smooth..
Gonna drain and inspect oil, getting rid of the oil fiter and adaptor and going with a remote style set up.
Thanks Guys
I tapped amd threaded in allen head socket plugs. I did not have clearance for any type of cover plate.
I ended up going with a remote oil filter setup and ditching that oil adaptor
