Injector orings

I pulled my injectors today for them to get rebuilt. I only seen 1 oring with damage and it was o e of the black ones at the top of the injector. Could that cause the truck to use 2 gallons of oil in 10 mins of idling? Also the driver side was missing all the oil spouts. What problems would that cause?

I wouldn't think the top o-ring would cause you to loose 2 gallons in 10 minutes of idle. Any signs of oil in the tail pipe?

The missing spouts are going to make things messy if you run it without the valve covers on. As long as the oil stays under the valve cover I'd think you'd be fine without them.

No oil in tail pipe. It's been using probably a Gallon every 200 miles or so and yesterday it just got really bad 2 gallons in 10 mins and it wasn't smoking no leaks. I think I read somewhere there is orings inside the injectors that can fail wonder if that could cause this?

If the top O-ring is damaged (the square-ish one?), the injector can work it's way loose. I got a piece of that one.

If the the third O-ring down from the solenoid is damaged, it will shove your oil into your fuel. What color is your fuel filter? There are internal seals in the injector that can blow, also sending dinosaurs on a dead run to the fuel tank.

The fuel is normal color but the truck has been doing this for a while and the oil in the engine is brand new color. It started this right after a oil change and I've just kept adding oil didn't want to take the time and money to fix it right with the holidays but now I don't have a choice. Also checked radiator resivor and its not in there.

You might want to check your turbo. It could be passing oil like this.

That link wouldn't load but if the turbo was passing that much oil would it not be dripping out the tailpipe or the intercooler tubes be covered in it or the engine smoke really bad? Getting none of that. Just uses a lot of oil and its hard to start

I will look into the link. No I did have evidence of oil leaking,dripping,etc. anywhere other then my oil level kept dropping. It wasn't until I got low compression in a cylinder that I started to even see smoke issues.


Maybe this one will work.

Holding on a sec.... You had your oil changed by a shop, then lost oil like crazy? Unless they turned a wrench on something other than the drain plug and filter - they could have either left the plug or filter loose, or put the wrong oil in. I would be absolutely certain there are no oil drips anywhere under the truck.

No I changed the oil but when I did the problem came up this is my 5th 7.3 and I do all my own work so I'm kinda familiar with how they work. I'm just wanting to make sure the injector cups can't cause this I think that's a coolant mixing with fuel or oil issue tho.

The truck does not leak a drop there is no oil in the valley. I really think it's going to the fuel but with the oil as clean as it is I don't see any black. 6 of the injectors say some #s then AD them. Then 2 are a lighter color and say AP then some #s then AD.

I misunderstood. We're back to our regularly scheduled hunt and peck.

This has Cody test written all over it. You can pull the HPOP line to the head and use a rubber-tipped air nozzle to puff the fitting on the head. Be sure to really wrap a rag around that - it spits like a camel when you let go. Listen for air leaks and watch for oil discharge.

Hmmm that test wouldn't do any good with the injectors out would it?

Nope. The oil rail is wide open with the sticks out, I didn't realize you kept them out.
