What is this?

[MossBack]

The injectors in the truck are less then 4,000 miles old. Glow plugs new too... This crap was over all of them. Has to be something in the oil. Any insight to what it is?

What's it look/feel like on a rag?

 

[Spatel23]

looks like coolant and oil mixed?

 

[ghohouston]

Is there just a bit of it inside the valve covers, or does all the oil look like coolant has mixed with it? I've seen a few trucks that get what I can only guess is condensation under the valve covers. But I'd drain the oil, set a new bucket under the oil pan, leave the drain plug out, and pressurize the coolant resovoir to 15-16lbs, and let it sit.

 

[MossBack]

It is only under the vc's and the oil in the pan is pretty good... I will consider pressurizing the system.


It is kinda gelly but rubs in kinda like Vaseline or grease...

It is killing off the injectors so I am going to open up the high pressure oil reservoir and change the screen
It is wired that it hadn't mixed together though.

You may have caught it right when it started to happen. Is the coolant level low at all?

 

[MossBack]

Yeah at the bottom of the bottle

Check your oil cooler's o-rings or it might be rotted internally. Or it can be a cracked injector cup(s). Bearings and coolant don't like each other.

It is Not coolant.

Well if it's not coolant...someone put an additive in the oil that sucks, or possible a fuel additive on the oil.

If that "gutter" aka cable tray that runs across the front of the cowl gets broke or removed, water pours right into the valley and it lands directly on the ridge of the passenger side valvecover. Water will get into the bolt holes around the vc. Looks like that or coolant.

I dunno man, I used to power wash the HELL out of my motor, like every few weeks I'd power wash it spotless, and NEVER found anything like that under them. I'm not saying its not possible, I've just never seen it happen, anything is possible.

It is seafoam. The customer finally confessed of 2 things. 1. He has run wvo, homemade bio, veggie oil and waste motor oil.
2. He hadn't changed the oil in 2.5 years before the first time I did injectors (12/30/13)
