I've been waiting to get my car back for weeks. The guy finally finished installing my new motor and everything this weekend. Fires the thing up, runs and sound loud and good but there is no oil pressure...basically he said I have a bad oil pump (the oil pump is new) and now he has to take apart the whole engine to get to it and fix it meaning I gotta cough up about 600 more dollars!!! Anyone had this problem before with an oil pump? It's a ported ls6 oil pump

it was built by ls1 performance. I bought the engine off of a guy on here that got it from them. I have my own mechanic doing all the work. I just called my mechanic and he said thats what he first thought so he checked it out and said that was fine.

probbly a pinched oring would be my guess highly unlikely that a new pump would be junk. not saying it isnt just very unlikely. also he doesnt have to tear apart the whole motor just pull out the stuff to get the front cover off. like 2-3hr job tops

two things i have seen make a brand new oil pump bad 1. the inside cam gears are seized because it was improperly ported and not cleaned thoroughly afterwords, and my very own because i did not prelube the inside gear and it just locked up and would not spin its a easy mistake costly though i cant really see anything else because its a fairly simple device but anything is possible i guess

So your mech verified the no oil pressure with a stand alone gage setup??? I'd have him show me in person. Besides as stated before changing out an oil pump should only take 2-3 hours anyways and at a std 70-80/hour I still only see 240 in labor, should be able to recover 80% of your new oil....
