I'm going crazy!

I have been waiting for my truck for too long. Now they can't get any low oil pressure. My truck has been down over a month....I bought a long block from PMM, and everything else that needed to be replaced. Now, I get a call saying they put everything together but there is no oil pressure. So, they are on the phone on Fri. with the guys from PMM and they still can't figure it out. What do I do if they say that something is wrong with the long block? Or if they just put it together wrong? Can they mess up the long block by trying to figure this out? I don't want to pay for $2700 for labor and have to take the truck somewhere else to have them figure it out.

Depends on which oil pressure they're talking about. HPO or LPO?

[FAAST]

They are saying LPO

[dhanna6powerstroke]

Possible check valve or regulator issue. Did the long block come with new front cover and LPOP or did they swap them over?

It came with everything here:
Performance Machine & MFG. 2003-2007 Ford PowerStroke Diesel 6.0L Long Block Engine Assembly

Comes with new pump but no regulator. I'd start there.

Thanks...I think they replaced that because they had an issue with the one from the bad motor. Can they mess up the new motor because of the the lack of low oil pressure? I just don't want anything else to go wrong.

I wouldn't think so. That's one of the plusses of our injection system. No oil pressure, no start.

Should have just taken the truck back to the previous owner and demanded your money back.

if they're not isolating the low side when testing (doubtful), then a high side leak will cause a lack of low side pressure. the low side needs to be dead headed to confirm
