New engine?
Hello I am a new member.
I have owned my 2005 v10 ex since 60000 miles. Have had many dependable family road trips and love my truck.
Recently it has started puking coolant and the overflow tank smells like exhaust. The oil cap has some coolant sludge on it. But there is no coolant mixed with the oil. Or oil in the coolant.
I am pretty certain these are the signs of failing head gaskets. The truck has 193000 miles on it now.
Want to keep it on course. But keep it reliable. So do I buy new engine or do I just replace head gaskets?
Thanks

I would begin with compression and leakdown checks to confirm suspected issues. If it's hg's I would probably have them done. There are plenty of these with over 200k and as long as you did your part with oil changes and general maintenance, it should do 200k more after

Thanks will get a rental tool from parts store today to do compression test.
Also is there a link on cylinder head removal on the ex? From what I read some say u have to remove the motor or lift the cab? Can it be done in truck?
Thanks

It can be done in the truck, I've seen several videos of folks who pulled their heads to do the exhaust studs and they did it without pulling the motor.
I don't know of a how-to on V10 head gaskets but I will try looking for it.

I had a similar experience with a neighbor's truck.
Ended up being an waterpump that was worn but not weeping. Would cool the truck at idle and short drives, the minute you gave it some gas it would puke coolant.
How bad is the sludge on the oil cap? My old Expedition and even the new Excursion has quite a bit of it since I don't drive it too often, hence the sludge.
Definitely do a compression check but don't rule out a water pump/thermostat issue just yet. I've seldom heard of these motors popping head gaskets.

Well that's good news that they don't usually pop head gaskets.
I have driven my truck every day. It never sat so it shouldn't have condensation or coolant sludge on the oil cap from sitting right?
When the issue started I replaced the water pump thermostat and clutch fan. It still pukes. Now I am starting to see some oil in the new coolant and it smells more like exhaust than coolant.
I am currently getting a second vehicle to a dependable state before I get to compression testing the ex. As I need some kind of transportation in the meantime while the ex is down figuring out why she's sick. In the mean time I use it only to take short trips to get groceries or run 3kids to school. Second vehicle is at point that I just need tires and it can replace the ex by tomorrow. Then I should have more info on the diagnosis.
Thanks all for the help so far. You all have calmed my nerves as when the truck breaks I think the world gonna be ending lol.

On the oil cap I can see yellowish orange drips hanging off. This stuff is also in the filler neck

You may well have bigger issues, however short trips where the vehicle never fully warms up can lead to a nasty oil fill cap with moisture. The cap alone isn't a good troubleshooting indicator, but combined with other symptoms can indicate a problem. Pressure testing and compression/leak down testing should tell the tale. Good luck!

dont bother renting tools. if you own a excursion you might as well buy them, youll need them more then once.

Short trips are far more detrimental to the lifespan and longevity of an engine that long ones, just putting that out there. If the temperatures don't get hot enough to burn off the condensation and impurities, then you getting a lot of sludge.
I'd personally drive the X as little as possible lest you cause even more damage. It already sounds like the condition has worsened, and if the coolant and oil are indeed mixing.... if enough coolant gets to the wrong place at the right time, you'll be looking at an engine rebuild instead of a simple head gasket job.

What he said about the short drives. They're not great on batteries either. One of my other vehicles really hates sitting or being driven on short commutes days on end; the battery will get noticeably weaker when I turn it on. A long drive will fix it though. A good ol' Italian tuneup doesn't hurt every once and awhile either.

When my 62 Corvair used to plug up carb jets, an Italian tune-up would bring them back most times. Had to go full throttle, then hold your hand over each carb as it was coming down for max vacuum. Haven't heard the term in a while. Lol.
