I'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 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 RepliesWhat 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 RepliesNext mods are for the fuel rail cross over and the high pressure oil cross over. I see the unused ports will come in handy.
Fuel delivery? any specialty mods to run the fuel lines? I see it's a #4 ORB fitting. Anyone ever use a "T" or a splitter off the fuel bowl to have a quad line set up?
Saw the FRx from RiffRaff .... not sure how it eliminates air from the system 7.3L Diesel Fuel Rail Crossover? (FRx) 99-03 Powerstroke
I'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 3rd HP power steering line last night( 3rd in 300K, always blows the same point....fitting comes apart where it attaches to the pump.
I'll start, mine have gone about 100K plus or minus 10K, almost thinking about making it a 100K maintenance item.
My 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 RepliesCouple of years ago I installed a fuel pressure gauge. I wrapped the fittings with teflon tape. Well within about a year it started leaking. So I shopped around and used Permatex Permashield fuel resistant sealant on the fittings. It says diesel resistant on the package. Couple months later leaking again. So I take it apart again, clean every fitting and follow the instructions to the letter. Well its leaking again. What will resist diesel fuel under 55 psi pressure. All the fittings seem to be pipe thread.
View 7 RepliesI have an 03 Accent. The all metal high pressure power steering line had a leak. So I bought a new one for around 70 dollars from Hyundai. This part has a curved shape and fits around the radiator. The old one was difficult to get off, but the new one is proving impossible to get on. I cant get it into place.
View 2 RepliesTruck 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 RepliesI 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 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 have a 2003 Ford Excursion with the high pressure line leaking. My guess is that the original line had a rubber hose and was replaced with a 3/8" ID high pressure hose. My problem is that I can not get the 3/8" ID replacement hose over the second larger bulge on the line going to the radiator cooler. What am I doing wrong?
View 3 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!"
I'm doing standpipes and dummy plugs. There is a 4mm plug with an oring and mine was trashed. What is the P/N?
View 13 RepliesMy high pressure power steering hose just blew at the "B" nut at the pump. Meaning, the fitting is still in the pump but the line is out. Do I need to replace the whole line or is there a retainer I can swap out?
View 14 RepliesI think I've tracked my power steering leak to some type of sensor on the pressure line, close to where it connects to the steering box:
I assume this is a pressure sensor? I got no CEL or anything like that when the fluid had leaked down to the level that the pump started whining pretty badly though. As far as I can tell by looking at pictures, the parts store replacement pressure lines do not have this sensor, or any provision to connect a sensor to it: Advance Auto Parts: Power Steering Pressure Hose by Powercraft - Part 71878
I may just put a replacement line on there and leave the sensor plug hanging and see what happens...
I 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 RepliesRemoved my oil rail to replace standpipes/dummies (04 Wavy rail) and now I have huge crank times to start. This is after the initial Huge crank to get it started. Do I have air in the system, or did I bugger something. I did the whole deal very careful. I lifted the rail up very carefully, pipes removed. I lined up the rail nipples with the injectors and evenly pressed it back in place, and then inserted my dummies/standpipe. Tightened the rail to 120 inch lbs then the dummies/standpipe to 60 ft lb. I did my son's '06 a month ago with no troubles. (didn't remove rails though). Once running it sounds perfect, turn it off and re-start and it's a long crank (30 seconds or more). I have not monitored ICP/IPR while running, will try that today.
View 8 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.
