Ford 6.0L Power Stroke Diesel :: Lower Valve Cover Bolt Missing - Oil Leak
Apr 1, 2017
Just got off the boat (offshore boat captain) and my wife has been using my truck while I was gone so it doesn't sit for forever. I made a quick trip to the hardware store for some materials and back to the house. Total drive time was about 20min. Noticed that I had a terrible shake like a weight got thrown off a wheel. When I got home and started looking at my tires I was on the passenger side front tire and noticed oil on the driveway. That's when I saw the drop.
Now I climbed under the truck and looked around and found oil all over the passenger header and starter and basically all down the passenger side of the motor. I popped the hood and and the valley was clean. Then I felt around the passenger valve cover and found a lower valve cover bolt missing. Second from rear on the bottom. My question after that long description is, can one missing bolt cause a leak bad enough to completely clean the oiled areas and start the truck and in about 1 min have clean oil dripping down? If so, when I get a bolt should I go ahead and replace the gasket?

I have an oil leak on a 04 f250 6.0 stock. It has 292000 miles on her. It started as a few drips on the pavement about the size of a quarter and now has escalated to a steady trickle. It's on the driver's side in front of engine running down the corner of the block and dripping off the oil pan. I pulled intake plenum and everything and I thought it was coming out of the valve cover but now it looks like its just under the valve cover. It looks like its coming out of the front corner of the head. Its wet there and looks wet around the glow plugs. I cant run it now as I've drained the oil and coolant. I don't have a gauge or anything and its plain stock.

I have a oil leak that I can't seem to find it appears to be leaking down above the passenger side valve cover and then goes under the engine cover. I don't notice much oil in the valley. This is a 2011 f250 6.7 with 116000 miles on it. I have had no other problems with this truck. Could this be the turbo lines? I am on a RV trip several hundred miles from home so I have very limited tools. The leak doesn't appear to be bad at this point the valve cover is wet with a small drip but it's only in the middle. I just changed my oil prior to the trip when I noticed the leak. I did have a leak on the new filter but a new filter fixed that but still have this one higher up.

The bolt that holds the dipstick on the valve cover. i have tried for ever to get this thing off. soaked it , got a skinny wrench on the nut underneath but think it might be stripped (1/2 inch grinded out a little). going to try and get a set of skinny wrenches tomorrow , mine bent. tried vise grips on top of the bolt and put a box wrench on the nut , and gave it my all. The damn thing won't budge.
Also, any tips on the rest of the valve cover bolts. I had to remove some from inside the fender well but barely got to them. My question is not getting these out but getting them back in. And how the heck to you torque these things??? The bolt i mentioned above is creating problem, and I only have so much time

As far as I can tell, the rectangular breather is full of some type of stainless mesh. I cannot separate the halves. I may have pulled a bonehead move and left it tin the solvent tank and didn't realize it was still on....ofcourse it was full of solvent. Just cleaned it real well. I drained it and am going to let it dry out before install next week.

Trying to get some assistance on a mystery oil leak. I see wetness above the oil pan on the left side near a tube. That is the most fresh oil I can find at the highest point. The passenger side and starter also have drips, but i am thinking it may be running across the oil pan rail as I cannot any source on that side. Also, recently started having a rough idle - surging. Of course I thought ICP, doesnt feel wet.

Was replacing my cracked and leaking charge air cooler pipe Friday evening and noticed oil all over the place at the lower front of the engine. It has been a few months since I've been under the truck. No drips on the ground so it must be a slow leak while driving. Oil level is fine so it hasn't been leaking for long.
Any ideas from this limited two picture view? Front main seal? I've been reading the vacuum pump leaks oil as well but I'm not sure where that is other than driven by the HPFP. I took additional pictures but those were useless, it's a bit cramped in this area.
In the past ten months I've had the turbo coolant inlet pipe leak repaired and then the DEF heater failed, which means replacing the entire pump of course. The wastegate solenoid air compressor noise started some time ago as well at shutdown but I haven't been concerned about that (it doesn't seem to cause an issue). 96,000 miles.

I've experienced a fuel leak, I've checked all over, and the only thing I've came up with so far, was maybe its coming from the banjo bolt going into the front of the driver side head.. I cant really get to it good enough to tell though..

Just had to replace radiator at 38k on my 2012 SD. Now I have another leak at 41k. Looks like it's wherever the lower radiator hose leads. Kind of a weird junction. I don't think it's coming from above there, but not sure. It's the primary dgas bottle that was low. The radiator was covered under my ESP. We'll have to see what's up with this one. Been eying a denim blue SD at dealer, thinking this is going to talk me out of it though. Not especially happy right now.

Just wondering if your fuel drain valve leaks at the knob when you are draining for water? I opened mine yesterday to drain it for the first time and fuel went EVERYWHERE!! Unlike the 6.4 that I was able to use a bottle to capture the fuel in, my 6.7 leaks around the knob and comes out the drain port. After some very colorful words, I got it drained and then closed. I mean, why put a drain port on it if it is going to come out around the know and soak you.

I was loosening the bolt that holds down the number one spark plug wire when it just spun off leaving less than half the bolt in the valve cover. I tried using the grabbit extractor but that did not work.

My 2000 f350 is leaking oil from a bolt on the passengers side valve cover. it is one of the bolts on top of the valve cover. Can I just remove the bolt and put a rubber washer under it or do I need a new valve cover?

I looked around and couldn't find the specs for the valve cover bolts.. I'm assuming it'll be a pretty low torque like 20 ft-lbs.
This'll be the 2ZR-FE 1.8L engine.

doing injectors and pulled the valve cover, and noticed its not as clean as i expected. in the oil on top of injectors i noticed its got some grit in it. this cant be good and not sure how this debris got in there as i always change oil and air filter regularly( unless previous owner neglected). is there a safe way to clean this? Is this a normal find for you guys that have done injectors?

Brief back story, a year ago my timing belt went and had to replace the cylinder head and all associated parts. No problems since then, until now. Recently the check engine has come on, and got the code for an exhaust leak. Can't remember the exact code number, but the leak wasn't causing a lean condition or causing the engine to act weird so I left it until I had to time to find the leak. On the way home today I noticed an exhaust leak that got increasingly worse to the point where at a stop light I'd go to accelerate and it would pull away very sluggishly. Got home, opened the hood and tracked down the exhaust leak to somewhere around the manifold/downpipe/turbo area. I took off my cover and noticed what could be a bolt missing, and upon further inspection a bolt that may be coming loose.
Here's what I'm referring to:
- Missing bolt?
- Loose bolt missing bolt?
- Loose bolt?

I had the engine out of my truck (7.3 with e4od) to do manifolds. Anyway, I got it back in and started it up. Since there was air in th fuel lines it had to crank a couple seconds but started up. I looked and now fluid coming out, then it sat for a few minutes running and I took it for a drive. While sitting in the driveway it wa smoking a bit. But I thought it's from the oil I got in the exhaust while drilling two of the manifold bolts and soaking the bolts with ATF/acetone. After about half a mile I thought that maybe it's more oil then that would cause... So I went back. I looked and the inside of the exhaust is covered with oil, and the rear of the engine is also.
When it was out I capped all of the open ports so I could pressure wash the grease off. Also, I flipped the CCV so I could do the delete. During instal, I missed the cap on the CCV and it was not able to breath. I think that maybe it built up pressure and blew the valve cover gasket? It looks like it's coming from the right cover on the backside; I had not taken this cover off while the engine was out. How much pressure does it build? Is it possible that it could have blown the gasket out? I have done the oil cap trick to test blowby and it always passed the test. What it could be? For the leak on the engine and why it's in the exhaust?

So, when I bought my truck, it leaked oil.....bad. It goes through around 2-3 quarts a week. I needed a vehicle, this one was cheap, so...I run it. Every other day, I put half a tank of gas and a couple quarts of oil in it. It leaks on the passenger side, right above the starter. I figured it was the valve cover gasket, and planned on changing it today. I saw a post about the "typical" head gasket oil leak, which sound suspiciously like what mine is doing. I have no oil in the coolant,or vice-versa.....

My 2003' Explorer XLT (4.0L V6) has an oil leak. I tracked it down to the passenger side, rear, bolt head on the valve cover (back by firewall). I took it to a guy who replaced the valve cover gaskets, but it is still leaking. He claimed when he had the cover off he looked for any cracks on it, but did not see any at the time.
Anyways, I was searching around and found several explorers leaking in or around the same area of the valve cover. And it turned out that there issue stemmed from bad timing chain guides, causing the valve cover to crack.
I do notice that on a cold start, I hear a rattling when I first start it up. It rattles for maybe that first 1-2 seconds when starting. Is this my timing chain rattling around? If that is the case, how much this could set a guy back on repairs?
I guess I don't know whether to just replace the valve cover, or if I should dig into it to see if the real issue is the timing chain guides/tensioner. Mileage is approximately 121,000....

2006 F350 4X4 .. How in the heck do you get to it? I have that massive heat shield in the way and can't get a shot at even those bolts? One bolt left to get out then I can start going back together.
