sixturbosix Posted April 28, 2010 Share Posted April 28, 2010 I have a 6.0l that is not making base oil pressure.I checked the regulator and it had a ton load of tension when i took it out so i assumed it had stuck open.I cleaned it up and cleaned the bore and it went back in normal but it still does not pump any oil to filter housing as if it isn't priming.Any ideas before I go deeper?

Fordracer Posted April 28, 2010 Share Posted April 28, 2010 I'd pull the regulator again to see if it stuck again. I had one that I didn't get all the pieces of metal out and it stuck again right away. If it's not stuck open again what went through the regulator probably went through the pump and ruined it.

sixturbosix Posted April 28, 2010 Author Share Posted April 28, 2010 I pulled it again when it wouldn't start after I cleaned it, and it seemed ok.Thanks. Quote Link to comment Share on other sites More sharing options...
Aaron Posted April 29, 2010 Share Posted April 29, 2010 For the amount of work it takes, you might wanna knock the LPOP cover off and take a look in there, and maybe take some measurements. When you put it back together if everything measures up okay, put a little bit of vaseline in there to maybe help it prime a little? Quote Link to comment Share on other sites More sharing options...

sixturbosix Posted May 4, 2010 Author Share Posted May 4, 2010 Found issue and vehicle is under repair.Low pressure pump was eat up.Looked like half a wire circlip went through it from the impression it left in pump gear.Could not figure out where clip came from until I thought about it for a while.HPOP fitting blew apart and half of the circlip inside the fitting got sucked into oil pump.

Coolcat390 Posted May 26, 2010 Share Posted May 26, 2010 Check the drain back valve under the oil filter. Seen a couple cause long cranks that show up as HP oil leaks. Quote Link to comment Share on other sites More sharing options...
