I have had a Jeep Grand Cherokee for about 4 years. Over the last year or so, I have been having coolant loss. At first, it was very little over the course of a month. Now it is about a half a gallon over a few days. We can't find any leaks. The oil does not appear milky. There is a bit of moisture under the valve cover. What could be the problem?

View 10 RepliesI've got a coolant leak here (I wiped away some of it before taking the picture):
Close up
This is the only place I can find coolant leaking and it's running down all the way to the water pump:
When I wiped away from just below the valve cover gasket it flaked right off and it doesn't appear there is any oil mixed in. I changed the oil today and it didn't appear to have any coolant mixed in either.
The coolant doesn't appear to have any oil in it's nice and pink as it should be. I started the car from a cold start and sat and watched the area waiting for it to leak but nothing ever came out, of course.
I know there shouldn't be coolant leaking from this area anyways but I don't know how else to explain the trail pictured. I definitely have a small leak somewhere as I've found coolant on the floor of the garage before.
Do I just replace the valve cover gasket and move on or is there something else I should be concerned with here?
I have a 1999 jeep cherokee 4x4 four liter inline 6. have a coolant drip at bottom radiator hose, change hose. but still drip. Could water pump be leaking. and it running down on the bottom radiator hose.
View 4 RepliesI have the 3.1 V6 in my 2001 Pontiac Grand Prix and today it started spewing oil out of what looks like an electrical plug in the front, toward the bottom just under the valve cover, dead center. What is this plug?
View 3 RepliesLooking for some insight into the state of the motor in a 2002 XD. Short story is that it appears to be leaking oil from the valve cover gasket (common, I know) and sometimes winds up running extremely low on oil before it gets changed. When draining the minimal oil in these conditions, non insignificant amounts of water can be found along with the drained oil.
Car is at 155k miles, has exhibited this behavior for more than a year, and has no noticeable knocking issues, power loss, mpg loss, heating/cooling issues, or any other ill effects other than apparently making a mess in the engine bay, on the ground where it parks, and scaring people when draining the oil.
Logically this is going to not be the case forever.... Thoughts? Prognosis? Treatment?
How do you replace egr valve?

View 10 RepliesWe were flagged down on the highway by a very nice fellow motorist because we were gushing coolant. It was gushing. My passenger was a guy friend who used to work as an aircraft mechanic and works on his own vehicles, so I deferred to his supposedly greater automotive knowledge when he said I didn't need to call a tow truck. We got to within 100 feet of my mechanic (about 5 miles away) when my poor Jeep conked out after losing power and making an increasingly loud clunking noise for the last 500 or so feet. We pushed it in to the auto repair bay. The engine was smoking and would not start. The mechanic replaced a worn out radiator hose, which had become disconnected from the radiator (due to swelling, I think he said?), and the truck runs. There isn't a discernible difference in the engine performance after driving it around town for the day. My question is this: is the engine likely to be FUBAR and am I just playing a waiting game until it croaks?
View 8 RepliesMy 1999 jeep grand Cherokee with 170000 miles with a straight line 6 cilinder has a knocking noise coming from the valve cover area. It is only present during a cold start and for about 2 to 3 minutes. Once it starts getting hot it stops. The engine runs fine it has lots of power and I do not have any other issues.
View 5 RepliesI have a 93 Jeep Cherokee, I just replaced the thermostat and the radiator cap, it's not overheating, however the radiator cap isn't even warming up and the thermostat housing heats up quite a bit.
The hose from the radiator to the thermostat gets very hot, but I don't feel anything being pumped. The coolant is also being drained from the reservoir, but I see little to none leaking underneath the vehicle. I pop off the radiator cap while it's in idle and see no movement and the coolant stays cool.
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.
so I have a 2azfe engine
So there's an oil leak coming from the valve cover gasket (just purchased vehicle dirt cheap with 220k)
found this
Notice all the oil sitting on top of the exhaust mani gasket
In the left(lower) part of the picture it appears to be scraped.
the gasket appears to be newer, I did NOT use a screw driver to remove the valve cover, which is what this appears to have been done..
Can this be sanded down then filled with jb weld, and then regasketed?
I have a 07 Sonata and having recurring valve cover leak. First time it happened it leaked onto my alternator and had to get car towed and whole bit. About a year later they discovered it again during routine oil change and had it fixed again. Yesterday during a routine oil change, they discovered a leak again!! I know this is an established problem but how many times can the same problem occur?? I'm passed the warranty (103K).
View 3 RepliesI have a 2009 Santa Fe Limited with 82000 miles. I have replaced four (4) batteries since it was purchased, new, in March, 2010. I have repeatedly taken it to the Hyundai dealerships in Las Vegas, Nevada and Centennial, Colorado, for an oil leak on the valve cover over the alternator. At no time has the service technicians at the dealerships ever told me there was problem. Last Thursday, the latest new battery, installed that same day, failed. I had my independent garage technician assess the multiple battery failures, with the associated battery display light illumination, related to the location of the continual oil leak. He stated that the cause of the battery failures was from the oil damaging the alternator. I contacted Hyundai Customer Service, today, and was told that there have no reported problems from oil leakage onto the alternator, with subsequent damage to it, and/or the battery.
View 3 RepliesI had a very slow oil leak that dripped onto the garage floor and i brought it into the dealership. They said it was a leaking left valve cover gasket; I searched and came up with nothing? The engine has just over 30K miles on it.
View 20 RepliesWell I popped the hood to clean my air filter and noticed that the top of the engine looked to sprayed with oil mainly on/around the front of the valve cover. I haven't really "investigated" to see where its coming from. Where it may be coming from!! It has 32,XXX miles and auto.

I recently did a valve cover repair to stop the dreaded misfire problem. Well, I'm still waiting on a few things but during the spark plug change obviously some of the oil from where the valve cover leaked previously fell into the pistons because I couldn't really clean it all out efficiently. This seems like it would cause a lot of problems? Do you think I should throw old spark plugs in there and let all the oil burn up before finally replacing them? I really don't want to foul up my brand new NGK's.
Also, I pulled p0300, p0305, p0306, so I am guessing oil in the spark plug/coil pack connection may cause some of the misfires, but do you think two of my coil packs are bad still? My plan was to move them around to see what happens after I get the new parts and am actually running again.
I just noticed what appeared to be an oil leak around the valve cover gasket, which the VW dealer has determined to be a defective cam sensor. Apparently the VW parts distribution center in Wisconsin has 530 of these in stock, so it may be a common failure. This is on a 2010 GTI with 28,xxx miles. Thought the community would like to know.
View 2 RepliesThis problem is from last winter. 95 Jeep Cherokee. After about -10 it just doesn't produce much heat. Heater fan works fine. Jeep runs plenty warm..but what i neglected to mention and or forgot to consider is... I have a tiny leak in the cooling system somewhere. I added just a small amount of coolant a couple of times over the summer and have witnessed a small amount of steam (not lately for whatever reason) coming from the front of engine compartment. I can't find the leak. My question is :Could this cause enough loss of pressure to affect the cabin heating system.....
View 19 RepliesMy wife's 2000 Jeep Cherokee has a failing A/C system. Last year it was blowing warm air in the middle of the summer so I took it to a local mechanic who recharged the freon and it was fine through the rest of the summer. This year it is blowing warm again so we took it in for another recharge and it only lasted a few days. The mechanic said there is a leak at the evaporator coil(?) He said the entire dash needs to be removed to repair and it would run about $1000 to fix. This seems a bit steep. Any thoughts or experience with this issue?
