Oil pump

Oil pump
Just did Heads and cam swap. Still tinkering with cleaning up headbolt holes as I’m paranoid about them and buttoning up everything but I installed a new oil pump and I entirely forgot to pour some oil into the pump before I installed it..So caught up with making sure I didn’t drop that dang bolt I entirely forgot. So I’m wondering if I can take oil pressure sensor out of back of valley and pour some motor oil in and if it will make it down to the oil pump? or am I just over worrying about this? Timing cover is already on and sealed up so Im kind of looking for a hack of sorts. Idk if I can get to plug on side of motor like the melling pump video explains due to pulley brackets and space. Or should I just not worry about it and crank it until pressure builds? also it’s a 2000 ls1 and the O Ring I pulled off of tube was red and thicker but o ring I put back on was blue and a bit smaller. But from what I’ve read that is the correct o ring. My pickup tube is not recessed.

When 1 quart of oil has been spend remove hose and reinstall galley plug with thread sealer on the threads to 44 ft lbs.

I was kind of under the assumption that doing that way the oil had to be pressurized by their nifty little oil primer that’s over 100 bucks. But alright sounds good. I have this cheapo gear oil pump That will probably work good. Thanks man I’ll try that

It's preferred to prime the pump by pouring oil in there or at least turning the motor over for a while before firing but if you don't it will most likely be okay and build pressure quickly. Pouring oil into the cam sensor hole wouldn't be a bad plan. Make sure and either put engine assembly lube on the lifter rollers, lifter cups, lifter to rocker cup and rocker tips over the valves etc or pour oil all over everything or both. Don't fire it with things dry in other words.
Pouring oil into the oil pump like mentioned above would be great. Don't necessarily have to pressurize it. I can't count how many oil pumps I have done and I have never pressurized one and I have also never had an issue.

Yea I have a light coating of redline on cam. And morels were soaking for a few days in oil and put in trays right out of oil so they should be pretty wet. After putting heads on I planned to leave valve covers off and pour oil across rockers and springs right before startup. The dry cranking i don’t understand so much solely because the time of slow cranking it takes. I’d think any assy lube would be long wiped rather than just firing it and having pressure in a few seconds. But I will definitely attempt to get a quart in through the front galley and see how much I can get into the pressure port. Thank you guys

I never fill my pumps. After assembly on a build, I prefill oil filter...which I always do, every time I change a filter...and just before the oil pressure sender goes on, which is last thing I do, I force squeeze a quart of oil down the oil pressure sender port. This will make its way to the pump. It takes a while so be patient. Then When I’m ready to fire it, I spin engine over WITHOUT spark plugs in for 10 seconds. This pre-primes oil pump, and allows all air bubbles in the fuel rails to exit through injectors. I ALWAYS have instant oil pressure at first startup using this method.

Hey, why spend when you can make something that works as well, and far cheaper!

Sad thing is, that was just the last few years.. Had an ongoing bill on the tool truck since around 2002
But yes, to do the job right you need the right stuff to do it. My advice, don't ever become a tech, go be an a/c man or just about any other trade, make the same money and not have to spend 30-40k on tools.

Can’t beleive I paid 50 bucks for a thread chaser.. lol but made me feel comfortable hitting the final torque value. For me I’d rather know it’s good and have piece of mind.

And LOL at the wood block, sadly it's very close to the truth though. What's even more disheartening is my 20 year old (FAR cheaper) craftsman sockets and ratchets hold up better than snap on and some of my matco stuff.
