Vaseline has its uses [Ahhemm] ... But I can't think of any automotive use, at the top of my head [no pun intended].
Some people use it to lube their rear ends, I don't agree with that ,, Could clog something up.

But seriously, something with tight specs like a fuel injector, like cm says, you don't want to put anything "gunky" in there.

As to the 0 oil pressure, wouldn't take very long to seize up if there really was no pressure.

 

On the no oil pressure deal, did you accidentally remove the oil pressure sending unit's electrical connector by chance and forget to re-connect it?

Just changing an intake would not result in zero-pressure at the upper end of the motor where that sending unit resides. Unless, you accidentally dropped something inside the lifter valley and, it made it's way into one of the oil passages and clogged it up, there's nothing else that would lead to no oil pressure other than a clogged oil passage or, a removed / damaged sending unit or wiring harness for that circuit.

 

When you changed your intake, did you lay clean shop towels or at least paper towels in the lifter valley before the gasket preparation stage?

 

Well I towed the truck to the auto shop at about 3:00 PM today, I felt I should take it there to make sure everything gets fixed right and make sure I didn't connect anything else wrong. They won't be able to fix it till tomorrow. But I told them that the leak is AT the connection to the fuel rail, and that my oil pressure gauge was showing no pressure. He said it's highly likely that I either plugged my connector in incorrectly, or didn't plug it in at all...

In either case he said he would check to make sure my truck was getting oil pressure just to be safe.

The first time I fired my truck up it ran fine for the 15-20 seconds I had it running and it didn't seem to be having any trouble except for the lack of fuel. I don't know how long it would take for a motor to seize up with no oil...

And yes I laid several shop towel in the lifter valley while I was replacing the gasket, and vacuumed the lifter valley out after I was done cleaning the gasket surfaces.

Thanks guys, and I'll let you know what the shop does so I can share how to fix it.

 

Then, in that case, it's your sending unit most likely. On the leaking fuel rail: that is due to the quick fitting not begin inserted all the way. If it doesn't snap into place, it pisses like a race horse all over the place.

Sometimes, all it takes is a bit of debris to lodge into the quick connect fitting at the flex line to hose it up. Most of those fittings rust out over time and, when you remove them, there's a tendency that rust becomes trapped in between the two fittings and causes it to not seal all the way.

 

Heard back from the shop. Apparently the fuel rail line got bent a little and that's why it's leaking.

Oil Gauge Wire I snapped or something so easy fix there...

Solution is new fuel rails and 1 new fuel line. $1200 Parts labor and tax. And it won't be ready till middle of next week.

Could not have lost my job at a worse time

 

Dang, quite a hit.
Why not DIY and save a bundle ?

 

$1200 WTF!!!! You are getting ripped off! I'm going to start working on vehicles full time, the hell with the construction industry.LOL

 

Yeah, I second that. The OEM rails were listed around 450-650 and, a new fuel line from the dealer is around 150 bucks. I would also think of trashing all that OEM junk and replacing the entire fuel delivery system with a custom system. It would be less too.

 

My God, even the fuel line is two pieces, and the one that needs replacing doesn't even require gas tank removal. And with all the cash for clunker crap, Dodge Rams and fuel rails for them are a dime a dozen in the junk yards.
