Need help guys I have an LS1 I removed from a 2001 Camaro SS. The engine ran great when I bought it and only has 10K miles since a rebuild. It has sat for about at least 8 months without running and the oil was drained last month to put it into another vehicle that never came with an LS. Now it's in and I hooked up a oil pressure gauge by taping into the fitting above the oil filter. I cranked it over for about 20 seconds (with the ignition disabled) and I don't seem to be getting any pressure. I have a brand new o-ring on the pickup tube (I had to use a different pan and pickup but stock parts). I have heard about LS dry start ups because of the location of the oil pump and length of the pickup tube. I was going to pull the filter off and see if any oil has gotten there yet but it has gotten to dark and I have to work all weekend.
Am I missing something or is this something normal and I need to crank it longer to get the oil circulating? I don't want to do any damage to my engine by just starting it and hoping for the best.
Ant help is appreciated, thanks.

There are a lot of factors here. Rebuilt, sat long time, is the pressure gauge working..... I believe new pumps are greased to aid in starting the oil flowing. Try putting a fresh filter on it and see if there is oil in it after you have been cranking. That will at least tell you if you are pumping oil. There is always the possibility that the gauge you are checking it with is bad. On a side note... i believe there is a orange plug under the rear seal cover that can cause no pressure if it fails. Try the filter and give update.

I was going to pull the filter next time I'm off work. I had thought about the gauge but I don't see any oil going up the line to the gauge.
I would pull the plugs but they are almost impossible to get to on my install. It will take at least an hour to get them out, but might be worth the effort.
I won't have a day off until Monday but I will let you know what happens.
Thanks

I made an oil primer for my engine and pumped plenty of oil thru it. Turned the key and.................still non pressure. I'm sure the pickup tube and seal are good. The pressure relief valve must be stuck.

Fire it and if you don't have pressure in a few seconds then worry.
Cars and random engines of all sorts sit for months and then are fired later and they are fine.
You aren't very likely to see pressure from the slow cranking speed of using the starter, if everything was perfect, maybe.
Seriously, fire it.

I got it all out. And ready to go back in. And don't know why I dreaded this so bad it's actually a easy job... now on to the oil pan gasket. When I built the engine I used the blue felpro with no sealant it apears. Never had a leak looks like I should put a little where it starts rounding up on the timing cover and rear main?

Yeah you only need extra goop in the "corners" or joints between vertical and horizontal surfaces to account for any gap or mismatch. Just use a little common sense (ALL of us have that, right? RIGHT???? lol)
