99 powerstroke hpop bleeding down

[yaterman8]

i know there is alot of topics on this, but i am stumped as where to start, if i let the truck sit for a day or to the hpop bleeds almost all the oil down, and if i fill it up through the plug it fires right up! i am just wondering if i should take it in or start with the basics, injector o rings, the liitle check valve down in the valley or what? any help would be great !!

Thanks
Rick

Are you saying if you "don't" fill it up it wont fire off?

[yaterman8]

it will fire it up eventually but it usually takes 3-5 times cranking it until it will start then it runs rough for a few seconds then it will run fine

are you leaking oil in the valley of the engine?

I have taken the check ball and valve out of the engine valley without taking the hpop out. If there's no engine oil in the valley, I'd start there. Make sure nothing is caught in the ball area that won't let it seal against the block. Don't drop the spring......you will need a good universal joint and some extensions.....its the size of a 3/8 drive ratchet.

If that's not your problem, you could have a leak from the resivior....in that case, you will have to remove fuel bowl and top of the resivior to see....

there is zero oil leak and zero fuel leak!!!!!!! do i need to order the check valve from ford or just pull it out and clean it?

Fuel leak is not an issue with this.

You can take it put and clean it and to look at condition. You will have to order one form ford. Its a three part assembly. Ball, spring, and the plug thing that screws into the block

I get what you mean on fuel leak. I'm talking about internal leak from the hpop resivior. It can leak back down into the block.

Had a 02 that did this and we ended up putting the LPOP on to fix the problem.

thanks guys! i think i will start with the check valve, is there anything i should be looking for when i pull it out to check if its bad?

thanks
