6.0 extended crank problem

Hey guys, Im having a very intermittent extended cranking problems Every now and then I get in the truck turn the key and the engine will crank a few extra seconds then normal but it only happens every now and then and usually when the trucks sat over night or it cools down a bit then I go to re start it, when it finally fires up there's no smoke doesn't run rough at all runs normal once she gets going, I'm thinking maybe a high pressure oil leak somewhere?!?! But I'm not sure about it.

Thanks

Sounds like a leak in the HPOP system. I see you already have the STC fitting so it probably isn't that. Maybe a leaking dummy plug or standpipe. You can read a lot about upgrading this stuff in multiple threads on here. Do some searching and you'll be surprised what you can find out.

Yea, heard cranking is almost always a HPOP leak. If you were getting smoke after startup it could be an injector problem but that isn't very likely especially if the truck is running good while its idling. Good luck

Well mine turned out the be LPOP for something simauar and I had the same symptoms until I didn't have oil pressure at idle anymore. But I would start with the HPOP area first

I've got the same thing going on that I've been trying to figure out for a while. Only does it when cold, so I thought that ruled out the stand pipes/dummy plugs??

The reason that I would rule out LPOP for you though is at idle I had no oil pressure and at and after 1k rpm I had normal oil pressure

Well I wanted to update you guys and tell you that it was the HPOP and it's ready to go. The one guy made a mistake telling me on the phone. But I'm about to go pick my baby up yay!

Mine is doing the same thing. When it's really cold outside, its fine. When its warm outside, it's better. When the ambient temp is about 45 to 30, it cranks much longer. My mechanic checked the glowplugs and they were fine.
