Thread: Oil not squirting from rockers w/ over 60 psi on gauge!!!

Tweet

I got another question...If I pulled pulled out all my lifters and primed my oil plump w/ my drill. Should I see oil flowing through the 2 lifter oil galleys? do the oil galleys come up from the bottom of the engine between each lifter bore too? or do they just come from the backof the engine and the oil flow from back to front-meaning that oil would have to "SHARE" the flow through the back set of lifters while it makes it way to the front of the engine? I gotta figure this damn thing out. If anyone has any insight let me know please.

Thanks Denny for that image. I might have to bring the damn thing in. I don't know what it could be now. I pulled and tore the engine down. Took the intake off and checked all expanasion plugs and they all were there. Took off all rockers and lifters/pushrods and then primed the oil pump. I get excellent pressure up through the oil pressure sender port behind the distributor.
While priming I could see some oil coming out of the passenger side lifter gallery in the hole right where you would stick your primer and drill down to reach the oil pump Tang. I could see Some oil coming out of the back of the engine out of the rear drivers side expansion plug which I took out. It didn't come firing out though like it does from the port behind the distributor. Should it come firing out like that port behind the distributor? I would think it would. I noticed after pulling my heads off that I couldn't get oil to come out of that rear drivers side oil gallery in the rear of the engine....does this have something to do w/ pressure? It was just coming out prior to pulling the heads.
I also found after pulling my heads that they were not drilled for steam holes-I knew it and my engine builder said they were drilled. What a jackass.
Well one last thing I did was check my oil pump pickup and it was off by 1/2 inch or so...I don't know if this would have affected that. I readjusted it so it is now 1/4 inch off the bottom of the pan. I never checked the oil flow after readjusting the pickup though. Any other insight would be great so I don't have to make a trip to the machine shop.

I am having a similar problem. I have a 1973 350 block with 1993 TBI & HEI. Completly reworked the block. I put a High volume oil pump in. New Cam .452 - 230 and Lifters roller rockers with 1.6 ratio. All new bearings, freeze plugs. It started just pine and said it had 40 psi oil pressure. I haven't even put it in gear yet. Maybe a totla of 4 min running. The first knock I killed it. I pulled the valve cover and I am getting no oil out of the valve covers. I did happen to notice a puddle of oil under the rear of the engine but thought it was the rear main. At a loss please help

I dont see a plug here. 327 must be different

The rear main seal has an orientation. The thick end of the seal goes toward the front of the engine. Heres a pic of what I mean. Remember I have a 327 chevy

what happens if you break a new engine in with syntetic oil?

Same with 20w50?

If you don't have a oil pump primer will the oil pump prime it's self up?

Oil! there is no real reason that u cant break-in an engine
with synthetic oil what weight u you use is up to you

The oil pumps should be primed by using a drill through the distributor hole to prime the pump. However the fact is your oil pump is self priming.... The reason you use the drill and run the oil up into the engine first is to reduce the amount of time your engine turns before the oil is there. Will yak with ya anytime DH

just unhook ur distributor wire roll the engine over till you get pressure at your gage. essembly lube should protect till then

hey thanks for the info. I'll let you know how it goes.

ok I got oil coming out of the rockers with the primer. I still only have a max of 40 psi oil pressure with a high volume oil pump. There was some bubbles on the dip stick. Will the oil pressure go up when all the air is out?

when I first start it up, it will show 40 psi then go down from there. All the way down to 0. I don't get it. Everything is new. Could I be starving the engine for oil with the high volume pump?

The oil pick up was welded on when I bought it. It came with a stud kit and hardened shaft. I torqued the oil pump down to spec.

OK the engine is cuming out. I talked to the machine shop where they did my crank and heads. The rear cam bearing might not be all the way up the the cap in the block. This was the first time I ever changed cam bearings so it sounds right.

It was the rear cam bearing. It was about an 1/8 of an inch away from the cam plug.
