Ford Excursion :: Leaking Coolant Hose Under Degas Bottle Behind Valve Cover?
Feb 22, 2016
My truck has a 6 o powerstroke. I noticed some coolant loss, which I've been monitoring since I had the truck studded 2 years ago. Today I was looking around trying to find a cause of the coolant loss and I noticed some crusty orange residue on a hose that runs under the coolant reservoir. The hose seems to go behind the valve covers along the firewall to the passenger side through a steel line, and then go in a loop back to itself?
I'm guessing it's for the heater core, but I didn't see where it actually goes into the heater core, or anything else for that matter. It is a molded hose that has one of those crimped transitions into the steel line, so I'm not sure if patching it is an option or if I should look at replacing the whole piece. I'm guessing it's going to be expensive. From the fact that it never failed before, I'm thinking it wasn't originally routed with it touching the valve cover and was just something that happened after having the body off during the stud install.

My worst fear realized when I saw oil pouring out of my degas bottle today. It was pressurized pretty good too. No coolant in the oil though. And no coolant coming out of the oil cooler after pulling the filter.
Ive had this 2000 Excursion since new and have 263000 miles on it with zero engine trouble. Ive always said if the engine goes its all she wrote. So I'm just sick!
Ive done every repair on this baby myself. Ive bragged on this engine for 17 years! Literally nothing but oil and plugs but my luck just ran out.
So, Im pretty sure I know whats wrong but Id like to hear what y'all think it is and how bad it is to fix. Ive searched this forum as usual which has never failed to steer me in the right direction but Im not finding the answer this time.

Found a tee on the heater hose leaks when it warms up. Appears the PO had noticed it but put a hose over it and now is leaking around behind the valve cover. This is a hard plastic line around 5/16. No online parts show it as being available. Is there a fix for this ?
I would bet several others have had this problem as it lays right on top of the flange of the valve cover where I think it would rub a hole pretty quick.

I have coolant leaking from under my degas bottle. There was a spot on the driveway this morning and upon investigation, I saw a drip hanging from the bottom of the degas. No liquid on top at all. Where this is coming from? Bottom hose?
Also, the boot that connects the tube (right side while looking at front of truck) to the elbow that goes into the intake is leaking oil and making a mess. Whats the best way to fix? Remove boot, clean up, and put back on? Or replace boot? If replace, where can I get that boot?

I have a 2003 Toyota Camry with 210,000km on it. Today I popped the hood, noticed the coolant was slightly low in the over flow reservoir so I looked around the engine bay. Now I know generally coolant does not go up that far and it's just oil... But this has got my head turning. There's a crusty coolant residue drip that looks to start at the valve cover. At first I thought maybe the water pump was leaking, and the pulley was spinning it farther up, or spraying back from a rad leak when driving. but the fact it's crusty and A clear line that looks like a drip that's a slow leak and has crusted over time makes me wonder.
I mean generally coolant wouldn't come out of the valve cover unless it was right full of coolant, causing enough pressure to push it out... Am I wrong ? Once I get to the shop on Monday I'm going to pressurize the cooling system and pull the spark plugs and the valve cover to look at the head, The highest spot I see the drip start is the valve cover, only thing I could think of is the intake leaking, and traveling over there but even then, it doesn't make sense to me. The thermostat housing is about 2.5" under so it can't be that... It's such a small leak, the reservoir is only down about maybe half an inch and the oil looks clean as can be.... There's some pictures below that you can somewhat see it.

My degas bottle is building pressure and coolants puking out. This happens after a light drive started months ago it sat at mechanic for 3 months he never touched it just wanted to replace motor so i brought it home. The truck starts and idles and runs fine temp gauge sits at normal. There was white smoke a few times several months back when it started up but went away after warm up but none now. I don't drive it i have a spare vehicle i tried doing exhaust gas test on degas bottle to check head gaskets today with no luck. They gave me the gasser only fluid with tester. No coolant on the ground and I've added the dye to see it with ultraviolet light no leaks around radiator.

Just bought a used 2011 ford f350 with the 6.7 diesel engine. Coming from a 7.3 1999 f350 with 330,000 miles, still going good. Took a 1000 mile trip on the 11 truck with out pulling anything did good. Hooked my enclosed trailer to it did a trip of 900 down and 900 back. Transmission temps were staying around the 250f, almost in yellow on gauge. Highest it went was 255f. Light never came on. Yesterday on trip without trailer was staying at 230f on trans temp. This is the first concern.
Second concern, had antifreeze coming out the cap on the degas bottle. Rolled over the hood and hit the drivers side windshield. Stopped un did the cap, it hissed. Put 2 quarts of antifreeze in drove on, this at 300 miles of trip. Primary water pump went out, half way there, at about 550 miles of trip. On trip back, about 1600 miles of trip, antifreeze was on windshield again. Undid cap, hissed, did not need to add any to it. Drove on no problems since. Have bought a new cap and installed.
Transmission doesn't want to shift right when its cold. First starting out. When it warms up shifts great. That's third problem.

I was towing my camper uphill and my 03 6.0 started missing and blowing black kid smoke. Next thing I know I hear a loud pop and steam is coming from under the hood and the truck dies. I pull over and discover the degas lid is stuck on and the bottle came apart at the the seam and the truck will not start. 6.0 with 120k miles

Passenger side valve cover leaking. My local parts stores have two brands.
Fel-Pro and MAHLE Original.
Any comments, preferences, anecdotes? I don't want to do this job twice.

My wife has a 2004 escape v6 (3.0L). The valve cover seal was leaking so I decided, why not change the plugs since I'm already going to have the intake manifold off.
I got down there, replaced the seal (just the front side, didn't want to disassemble something that wasn't broke) and then replaced all 6 plugs and boots (with springs). Fired it up and everything seemed fine. She went to drive to work and the CEL started to flash. I read the code and there were 4 (Don't remember exactly what they were), but it was a combination of things resulting from a misfire in cylinder 4. Since it was one of the front ones. I just pulled the plugged and replaced it hoping I had gotten a dud from the factory. Nope, still doing it.
I didn't take off the fuel lines, just the air intake on the top. I did not change the coils, but everything was running fine before I changed plugs so logic would dictate it is something I did. Only seems to misfire at higher speeds. Also, her battery light randomly comes on, but the battery and alternator test good. This has been happening a while.

I had it checked out at the dealer and they called it a "weep" so they went on to tell me that VW probably wont approve warranty work for it. I pushed for them to take pictures and send it in anyway.
Now assuming they won't do it, I have been looking for a DIY or a technical order on the job but I can't find anything.

Just found valve cover of my Tiguan is leaking out oil this morning. Will go to dealer tmr for gasket replacement. My car is just over 50k miles. What happened to VW's car quality control???

Haven't had the engine cover off for about 25k now (cleaned it up under there last time I changed plugs.) Took it off today and noticed it's a little oily on all four sides around the valve cover.
Pretty sure I can account for the oil that's near the filler cap... I don't recall spilling enough that would completely go around the entire valve cover though...
But how did it end up so high on top of the valve cover on the corners? It's even a little wet looking on the back if you look hard enough..
I only have 4600 miles left of the 10/100 warranty so I'm glad I caught this and hope the dealer can do something about it... or are they going to tell me this a "normal" amount of seepage? I haven't owned a vehicle with plastic valve covers before so I don't quite know what to expect.

I took it to the stealership to get the alternator and some vac. lines replaced all under an extended warranty. They informed me that both valve cover gaskets and right side cam adjuster gaskets are leaking. By no means am I a mechanic or close to but I am trying to get this stuff done as cheap as possible so I am going to try to tackle this myself.

So, weird smell that I thought was burning plastic or rubber is actually hot oil leaking from the valve cover and tensioner gaskets.
My car is nearly 8 years old (2003), and has about 70K. Should I go ahead and buy a timing belt kit and replace all that stuff at the same time?

My son-in-law came by tonight and showed me his ticket from his oil change at the dealer on his '08 Azera, 108k miles. Tech remarked that both valve cover gaskets AND the oil pan gasket were leaking. I've walked through his garage many times when my daughter has the car at work and I've never noticed any oil on the floor. Should have I seen any? I told dealer I would just drive it and monitor the oil level and any other signs of oil leakage. Since he bought the car with 101k miles and a fresh oil change ticket and never checked the level over the next 7k miles I don't think it's leaking bad.

2001 F250- V10... Lower radiator hose has coolant leaking - Right now I cannot tell if its the hose or the radiator itself (hoping not) - I tried to take the clamp off and it broke - Any tricks to removing the hose? its on there pretty tight.... I guess if I don't want to save the hose I can rip it off with a pair of pliers but before I do that wasn't sure.

I have a 2002 F250 5.4with Air Conditioning. The valve covers are leaking and the gaskets need to be replaced. I am attempting the valve cover gaskets. I was able to get the drivers side cover off with some difficulty. For the passenger side valve cover. There is very little " no" room to get at the bolts. I read somewhere that I may have to drop the engine on that side. I will do that if I have to.

A couple of days ago, I was driving my car around when the oil pressure light came on. Having recently changed the oil myself, I figured I had neglected to tighten something down there and it had become loose and was leaking oil. I stopped at two different shops. Both shops told me the leak was coming from the valve cover gasket. Instead of paying $200 for them to replace it, I did it myself. I didn't use any sealant or silicone, or anything like that. The old gasket was hard as a rock and had some sort of red cement around it.
After I had everything back together, I had a partner start the car for me. The oil leak has become much worse--probably a quart a minute. The thing is... I can't see any oil leaking from the valve cover gasket. You would think that an oil leak of that volume would be visible if it were coming from the top of the engine, no? We're going to take the gasket off again to inspect and perhaps use some gasket sealant in select spots, per some YouTube videos we watched.

I have a 2005 hyundai santa fe and the valve cover gaskets are leaking. We were able to change the one in the front but we cant figure out what to do with the back one. Need to find a video showing what to do...
