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?
View 1 RepliesThe 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
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?
My '04 F250 6.0L has 220k on it. I've had the EGR serviced several times and, unfortunately, the intake manifold boiled out in one of those services.
The engine light is on now and I've got "EGR Performance Problems" just below 2000RPM most of the time but not all of the time (runs better when warmed up)
I've been unemployed for quite sometime so I'm going to have to make this fix myself.
First question, of course, is should I plan to clean or replace the valve?
The second is how to clean the manifold chambers (? right word? The carbon accessible when the EGR is removed. I've seen people on YouTube scraping them with what looks like brake tools. Is there an appropriate tool or chemical?
The third question is is it going to be very difficult removing an EGR valve that may have carbon buildup on it? Too difficult for an aging seldom mechanic to think about tackling?
I guess those are good starter questions. I didn't know until today that EGR cooler may also be part of the problem. Unlike many of the people who post here, I have not kept good repair records. I don't know when I last had my EGR valve replaced at the Ford dealership but it was probably 50,000 miles ago.
The car: 1991 Honda Civic, 4 cyl manual Bought a month and a half ago. Past: I have been dealing with a slow coolant leak in the car that up to this point I have been unable to locate. No puddles or obvious leaks. Small amount of smoke out back, nothing like a blown head gasket, but a little more than average for a car its age.
~Ran a block tester - head gasket fine.
~Checked spark plugs - look fine, not too clean or dirty.
~There does also appear to be water in the oil from time to time, this is not constant, and I do not put water in my radiator (beyond mixing with coolant).
Today: Looking around valve cover noticed it was dirty. Also noticed some sort of sealant/caulking like material that easily came out of the seal between Valve cover and lower engine. I then began to drive the car and noticed small amount of steam coming from the hood. When I opened it up there obviously had been coolant spraying on the left side of the engine. It was difficult to locate a leak point, but appears to be coming from the seal between the valve cover and engine. I have seen it suggested else where that coolant could not leak from a bad valve gasket, but could be leaking from the intake manifold and look like it was coming from the valve cover. Should I just try to replace the intake manifold gaskets?
I'm checking my fuel filter regular (draining, examining.....basically OCD **** stuff) and I'm spilling diesel around the bowl. I've learned to put a rag around it now, but what's best way of cleaning diesel around that area? I'm tired of my wife complaining about smell. Simple green, purple power, etc???? Also, tell me what to watch out for.
View 14 RepliesAs 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.
View 4 RepliesJust 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.
View 14 RepliesI 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.

View 8 Replies I need to get the HPOP reservoir top cover off so I can drill/tap a gauge probe into it.
I see torque-head bolts, and a few long bolts that go all the way down into the HPOP.
Unfortunately I cannot get two of the torque-head bolts out because they only un-thread several rotations before the heads of the bolts hit the edge of the fuel filter canister/bowl.
Any tips or tricks?

So I'm getting ready to pull my engine to redo my timing cover.. my engine has over 320000 miles on it and it runs strong, dyno'd 402 hp at the wheels recently.. I was considering dropping a reman in since im pulling the engine anyway... I heard you can test for blow by buy sitting your oil cap over the spout and seeing if the cap blows off.. well the engine tilts downward in the back so the cap just slides off but in the dark when i shine a flashlight you can see the fumes just billowing out... how do i know if this is too much... what else can i do EASILY to see if my engine has issues before i start taring it down?

Any way to fix it without pulling the cover?
After running highway speed then stopping, the EBP valve is partially closing as you accelerate back up to speed. You can hear it in the sound of the motor, and you can see it on EGT's, which are rising quickly. This happens briefly then corrects. We unplugged the EBP sensor and the problem continued. Tube is clear.
If I monitor the EBP sensor, what values should I see if it is functioning properly?
So I just put billowed up pipes and changed the broken O ring in the turbo housing. Put everything back together and checked for a boost leak with the home made tester. Boots and everything ARE OK. I can hear air escaping from what seems to be the valve cover or intake. I realize that I am charging my crank case as well but it still concerns me that air is escaping from somewhere besides the CCV. I read the following forum and this guy had the same issue and after he found out he was charging his crank case he was no longer worried. . . . .
View 12 RepliesI just had my turbo and the EBPV on the pedestal rebuilt. Now I need to put it back into the truck. What is the procedure, if any, to adjust the EBPV? I only use the truck to haul a 5th wheel RV and the performance chip closes the EBP valve when going down steep hills -( EXHAUST BRAKE)
View 6 RepliesAfter checking my fuel bowl today for contaminants, I put the lid back on and then noticed a leak from the rear at drain valve. I know, I already ordered the orings. It was doing one drip about every three seconds with the truck running. However, I turned the yellow thing a couple times and the leak stopped. Not leaking right now. Maybe it wasn't shut from previous owner.
Second question.....After stopping leak and after routing my fuel drain hose, I decided to give it a try. No luck. Nothing out or drain. Based on my first fuel filter change, it may be clogged up. So, do I run wire from the bottom up? Or do I run wire from top (bowl) down? Just so you know, sucked the bowl dry with a vacuum device before I reinstalled the filter.
Iv heard a few things about changing the valve body. I tow a trailer so was wondering on pros and cons of changing this. And also what brands are recommended.
View 5 RepliesI have what might be a big problem, the main harness on top of the drivers side valve cover I can't get undone, the bolt holding it together is stripped or the nut who knows? wondering if there is any way to take it apart otherwise.
