LS1 conversion 2gen camaro Oil pressure first start issue..

[PatoRuzRS73]

Dear friends..

A week ago I started my new engine (conversion 04 gto LS1 on my 73 camaro) and run it for less than a min, a no oil press on the gauge (electric autometer). The oil sender is next to the oil filter. Then the next day I´ve check again just with the starter like 3 times.. 10 seconds turning without starting, and nothing, then took the sender out and turn it again and oil was coming out of the hole. I took out one valve cover and no oil got out when y turn the engine but still going out oil from the oil sender hole (with this I guess it is not a problem with the o-ring on the oil pump/Pick up tube as the oil is coming out.. i had to change the oil pan ans oil pich up tube for the conversion). The engine was drained and empty of oil for al least 6 months before this procedure.. I´m using motul 5w30 oil.

In between I orderd the blue ring just in case I have to check the one I´ve intalled, meanwhile I wait for the new oring to arrive I installed a mechanical oil press instead of the electrical one I used last time (this last ones was working good before doing the conversion maybe the sender is bad.) I did a new oil press test, took out all the plugs and start turning the engine just with the starter, and guess... the instrument started to go up until 30 lbs.. did this twice and the same results... ... no strange sounds.. just the sound of the engine turning...

Then did the same but looking to the valve-train .. turn the engine for like 10 second like for 3 times waiting a min in between... no oil came out on the rockers... just dont know what to do.. what do you think? maybe need more time to get oil there? also I think I will check on the original oil sensor with my electrical instrument... to see if i have the same press that the other instrument show...

Please need some coments on this.. i´ll love NOT to take out the oil pan to change the pickup tube o-ring..

I leave you a video..

Seems to me that you have a problem with your electric gauge, sender, or wiring, 30 psi just cranking the engine is fine.
