Truck has a high oil pressure leak, only leak i have found is in the high pressure rail, I cannot get to it till sat, or sunday. So I have to let the oil cool before I can start. Any way testing to find the right temp for Oil to thicken enough to Build? I've been here for hours and its went from 180's to about 100 now...
View 3 RepliesI have a High pressure oil leak somewhere, and where it can be. I tore the oil rails out and replaced the nipple cup seals last night. I got it all back together and air tested it and sure enough a leak is present. I have no problem paying for your time (I always provide good beer). I can rebuild gas motors all day long, but these diesels has me thrown for a loop. The frustration I am experiencing is crazy at this point. All the injectors are new, and the dummy plugs and standpipes were replaced as well.
View 11 RepliesMy 03' 6.0l hpop only makes about 1700 psi at wot, at hot idle the ipr is 25.1 and the icp is about 580. It runs pretty good but it seems the crank time to start is getting a little longer sometimes, other times it fires right up. It makes no difference if its hot or cold. Do pumps get weak or do you think I have a leak?....
View 1 RepliesI've been watching fluid build up on what I think is the hi-pressure line on the hydroboost. It appears to be originating at the coupling in the line because it is dry back at the unit.
Is there an o-ring or nylon washer in this fitting?
Can it be tightened?
Does the o-ring or washer need to be replaced?
Is it a sign of something else, like a build up of pressure in the line that is too high?
I currently have zero problems or noise coming from the steering or brake system.
I just replaced my injector cups a month or so ago and also injectors with some lower mile injectors. but now 3 weeks later still not getting any pressure at icp. I have dead headed pump got 3k plus but when i block off ether head i get no pressure. i have pulled injectors and checked for orings and they are fine...
View 2 RepliesI recently had an upper radiator hose bust and ever since I have been having a slight water leak. It appeared to be coming from between the layers of rubber on the new hose which I replaced twice since the incident. Both hoses had water seeping from the same location. This afternoon I plan on doing a pressure test on the cooling system to diagnose where the water may be coming from.
My question is could a loss of pressure cause larger than normal Oil and Water deltas? If I have to replace the radiator is there a particular manufacturer or type I should avoid? Should I try to get a factory replacement from Ford or would an Autoparts unit be sufficient? The original is still in the truck now with 286,000 miles on it.
I have a leak in the fuel pressure regulator housing. Seems like a common problem. I ordered the new kit from FICMrepair.
While I wait for the new kit to arrive, is there any risk other than loosing a few mm of diesel fuel driving the van? Will the leak damage injectors?
It's not gushing out. I have smelled diesel fuel for the past 3 months and could not locate it until last weekend.
The kit is coming next week and I like driving the diesel van over my under powered 6 cylinder E150.
I want to clean out the EGR while I have everything apart. I have heard that some people just disconnect it. There is a write up about in the tech folder and it went way over my head.
I have replaced hpop, lpop gears and cover, stand pipes, dummy plugs, rebuilt high pressure rails, and i still have issues. The icp readings on torque pro are mostly below 100 hot. I am clueless... I ordered the icp air fitting but it wont be here until tuesday.
View 9 RepliesI was watching a tv show a while back, I cant find the episode but I think it was performance tv, and they had a 6.0 L expert on there and he was saying they see a lot of high pressure oil rail end caps come loose and or pop out. He was saying that they tap/thread the end of the oil rail and put a threaded in cap? Does it make any sense, can it be done, is it worth doing?
View 14 RepliesI have a 04 F350 Dually and I am not getting any oil to my high oil pressure. Truck will crank but won't turn over. The high oil pressure pump is fine. What am I missing?
View 6 RepliesI've found everything there is to know about disconnecting the high pressure oil STC line from the oil rail on the early 6.0's, but I can't find anything about reconnecting them. Do you simply press it back on? Should there be an audible "click"?
View 14 RepliesProbably needs to get, f I had a part number for the A/C high pressure cutoff switch, and the 4 wire connector (2006 MY)? I guess for the 6.0L it is actually called "Dual Function Pressure Switch, DFPS".
Was dealing with some chaffing and wanted to add to my "parts list spreadsheet".
Base numbers:
A/C high pressure cutoff switch: 19D594
A/C cycling switch: 19E561
Found the clutch connector part number: Aftermarket - DD1085
Probably need to call this thread "I hate electrical problems also!"
After fixing my fuel pressure regulator leak, I found the fuel soaked track bar bushing coming apart.
The whole thing is available, but do the bushings are available? I've seen some poly kits for the '04 and older but nothing for the newer trucks. It's not a budget breaker either way, but it seem silly to throw away the giant bar because the bushing is shot.
If these will fit? 99-04 F250 Track Bar Bushings Red....
I noticed when I shut off the truck about 30-40 minutes later I'll open the degas bottle cap and notice there is no pressure.
I used a coolant pressure tester kit and pumped in 16PSI but couldn't hear or find the leak.
I'm going to buy a smoke machine in a month or two but until then, can I still drive the truck ?
I'm guessing it is a pin hole leak somewhere as once I shut the truck off... there is a lot of coolant pressure.
What is the part number for the high pressure oil rail check valves for a 2003 6.0L? I'm referring to the ones that screw into the oil rail. I would like to avoid the local dealer if possible.
View 6 RepliesI am doing heads studs and gaskets on the truck. I forgot to remove the stand pipe and started to lift the head off the truck with the engine jack. Well i bent the stand pipe and the port to the bock was a little loose. Tightened it back down and it seems ok. Could I have damaged anything by doing that? how is that all connected to the high pressure oil pump? I just want to make sure i didnt damage anything by doing that and since im already here I would rather make a fix instead of needed to tear down again.
View 5 RepliesRecently my 2011 F-250 Diesel with 21,000 miles seemed to start hard one morning. After starting the truck it ran well that day and started fine. The next morning it would not start. Had it taken to the dealer and they went to work. Started at the fuel filters and replaced low pressure fuel pump. Thought a piece of the defective pump had moved up fuel line. Removed high pressure pump and found signs of rust. All regular service intervals have been met. Didn't see this coming. No water in fuel light or other warning.
View 14 RepliesJust had dealer repair shop complete power steering fluid flush in Jan 2013. Vehicle now has lost all power steering fluid (April 2013) and dealer repair shop has told me it is due to high pressure hose failure - need to replace & then verify pump condition (dealer repair shop not sure if pump bad until hose replaced to test) for repair bill.. I was told this was not related to repair shop power steering flush because this hose not removed for flush or part of that procedure (at which time a transmission flush & spark plugs replaced (minor tune-up) . Just wondering if any pro mechanic can respond with advice about the relative close time frame these two events & if there may be a probable related reason?
View 4 RepliesI had new nitto snows put on my truck and low tire pressure light is on.....Checked tire pressure 65 front and 80 back.....Started truck and screen said tms pressure low.....Hit ok and drove around on and off for 2 days now and cant get the light to go out......Is there some way to get the light out or do I have to go to my dealer to have it reset???
View 14 RepliesLast week I was driving on the highway and noticed the oil pressure gauge showed no pressure. Limped a half mile to the mother-in-laws and called for a tow. As my truck was pulled onto the flatbed I could see oil all over the bottom of the engine, tranny, rear end, etc. Turned out to be a bad oil pressure sender, which was leaking enough oil to blow the plug off the top of it.
I replaced the sensor, cleaned the engine and under-carriage, checked oil level (which showed no loss of oil) and drove around for a week without an oil pressure gauge while I waited for a new pigtail. Put the pigtail in yesterday and drove it today for the first time since. Gauge was working, got to the bank and it was reading zero pressure again. Limped home and watched the gauge go back up quickly and then back down. This happened twice and was showing pressure when I shut it off. Checked under hood, no oil leaks and plug is still secure.
My truck gave me low fuel pressure and reduced pressure limp mode at 21,000 miles. The fuel and air filters were changed at 16,000. The dealer said all they found was the fuel filters (at 21,000) were what needed to be changed. Also, why does my truck hum??
