I have been monitoring my engine for 4 months now. I felt pretty good about the condition until recently.

Deltas are usually 8-11 at 65 mph depending on OAT. I am planning to do an egr delete, IPR remote cooler, IPR high flow filter, and then whatever else needs replacing when I get in there. I am not planning to do the studs unless the HGs are blown.......

I pulled the egr valve about 2k miles ago, things were mostly dry, but there was a SMALL amount of greasy residue on the bottom of the intake and the bottom of the valve. It was not as bad as some I have seen here, but there apparantly is some moisture of some kind in the intake. I put the valve back in and ran another 2k miles, and checked again......valve was pretty clean and dry, but the manifold looked a little greasy on the bottom, like the previous inspection.

I do not seem to be losing any coolant over the last 4k miles that I have owned it, there aren't any signs of puking.......is there ANY chance that this is something other than a ruptured egr cooler?

Without any coolant loss, I am thinking that if there is an egr cooler leak, it must not be a very big leak YET. Is it possible that the cooler might have a leak that has only acted up when the engine is under high load (previous owner had a heavy gooseneck trailer).....this might explain why I haven't seen any coolant loss in 4k miles that I have driven it.....just wondering out loud...

When I am ready to do the teardown, I do not want to do the HGs and studs unless necessary........should I park the truck until I do the delete?

Thank you :thumb:

Mine is the same exact way.......slightly wet, only on the flat bottom surfaces. No coolant loss, but I have a 24° delta. Just wait a few, someone will tell us we have blown egr coolers. Hehe.

How does yours run?

Mine runs pretty good, I even averaged 20 mpg's on a recent 400 mile trip. I seem to have a heavier exhaust than I remembered at first though. Seems like it is running rich, looks like black smoke on start up. I can't say that I see any white smoke that would indicate water ingestion.

Runs fine as far as I can tell, I just been makin short trips with it to cycle the coolant through my new coolant filter before I replace the oil cooler and delete the egr. No smoke whatsoever.

I am kind of anxious to get into it, because I think other things probably need attention. I am guessing that I probably have a butt load of oil in the boots, and the turbo probably needs attention too. Once I tear things down, I will also do some of the other replacement items. I am not looking to go high performance, so I am hoping the HGs are still good. I guess the only way to know is to run a test with a gauge.....where does one find those pressure gauges anyway?

Traditional parts stores, hydraulic shops, I think I ordered one from mcmaster carr. I dont have any decent parts houses around here. You need a 30 psi, larger or smaller will be harder to diagnose with confidently, unless your gaskets are toast.

It doesn't matter treg, you gotta fit it up to a hose, I used 3/8 hose. Whatever is easiest for you, just best to use the 0-30 psi guage.

I've come across blown EGR coolers on accident with no moisture anywhere near the valve.

Greasy looking valves don't mean for sure the cooler is blown, neither does a dry valve.

Yea, my oasis says the egr cooler was changed at 97k, i've got 169k now. I'm mostly concerned with my oil cooler now, it's getting replaced a soon I can afford it. It's not my dd.

When I deleted my egr the intake manifold was as you describe. I had a lot of oil coming from the ccv, perhaps that's what is making it look wet.

Yea, I guess you have a valid point.

Thank you for the tip, ordering one now:)

Interesting thought here...perhaps some could even make it to combustion....maybe that is where some of the excess exhaust smoke is coming from. I guess oil would be blueish?

That would be correct, blueish gray. Oil plus soot turned my intake into a tar trap. My egr was not leaking when I removed it but the black gunk I pulled out was very nasty

So does your truck have alot of blowby, or did the cac and hoses just need to be cleaned?

I did the CV reroute when I did mine. It needed to be cleaned of oil but it was not smoking out of the exhaust. I bought the truck used from a dealer that was not a ford dealer so I would imagine they didn't do the proper service to it before I bought it. Since I did the egr delete I also did the ccv reroute at the same time as well as a intake cleaning. Truck was running fine but felt much better after the intake cleaning.

Thank you for the input guys. Given no coolant loss, I think this may be what is going on with mine. I would also describe the residue in the bottom of the intake as "tar". Time to read up on the CCV mod.
