Hard Start when downhill
So... for some strange reason, my 2002 F-350 7.3PSD Auto, has been extremely hard to start when its faces downhill, even slightly. Has anyone had this problem or even heard of it? It'll carnk over and over and over, lots of smoke, but no fire and then whatever happens it fires right up, not sluggishly, just like a switch is flipped and boom, away it goes. If I park it with the nose uphill, its ok. Its giving me nigthmares, thinking about things it may be, so does anyone know of any common problems like this? Thanks in advance

Welcome to FTE. I've read of this once before, but don't remember if they ever posted the outcome. After leaving it parked down hill for a while (when you have trouble starting have you checked the oil level in the HPOP reservoir? It should be within 1" of the top.

It depends on what's causing it. If it's something simple, like the engine oil level is too low, that's a pretty easy fix. If the reservoir is actually draining back through the valve or the lube oil pump is having supply issues it becomes more difficult.
Or....you park it with the nose up hill. Sorry....couldn't resist.

So if the leak was between the front cover and the reservoir, would i see the leak? Or would it be leaking internally somehow? Sad to admit, I'm a mechanic and I just don't want to start ripping it apart without a little clue of what to look for. I wouldn't say that its the lpop, because the oil pressure gauge shoots up fairly quick while cranking over. I haven't taken a peek inside the hpop reservoir yet, but maybe I'll do it right now, since its nice out... back in a few

I've never even looked at mine and am not going to go outside and look right now, but try a little PB Blaster on it and wait about an hour and try to loosen it again. I know the level should be no lower than an inch below the top no matter how long it has been sitting. If it is lower than that it must be bleeding back into the sump somehow if it is not showing up on the ground.

I forgot to answer this question. Yes, the leak can be internal and not seen.

It's not in the reservoir.
