FINALLY AN EASY WAY TO FIX HIGH PRESSURE OIL LEAKS

AGIAUTO · #1 (**permalink**) 02-22-2013, 08:56 AM

WE RECENTLY HAD AND 05 F450 IN OUR SHOP THAT WAS DRIVING US INSANE, WHENEVER IT WAS HOT FROM HAULING LOADS IN THE DUMP BED IT WOULD NOT RESTART HOT, SO AFTER A PUMP, STANDPIPES, BRANCH TUBE AND EVERY OTHER O-RING ASSOCIATED WITH THE HIGH PRESSURE SYSTEM WE FOUND THAT ON THE DRIVERS SIDE, NUMBER 6 INJECTOR HAD MISSING BOLTS AND THE TOP OF THE INJECTOR WAS LOOSE ALLOWING OIL TO PASS, APPARENTLY TO MUCH WHEN IT WAS HOT. THE PROBLEM WITH FINDING THE LEAK WAS WHEN WE APPLIED SHOP AIR INTO THE PASSENGER SIDE OIL RAIL WERE THE SENSOR GOES THE CHECK VALVE IN THE STAND PIPE STOPPED THE AIR FROM REACHING THE OTHER SIDE AND ALLOWING US TO NOT FIND THE LEAK, OUR TECH FOUND THAT HIS OLD EMPLOYER HAS DEVELOPED AND PATENTED A LEAK TESTER THAT WORK THROUGH THE REGULATOR AND ALSO LETS YOU TEST THE PUMP AND SENSOR. THE ONLY PLACE I KNOW HE SELLS THESE IS ON E-BAY UNDER "FORD 6.0 TESTER" OR FROM HIS SHOP. I THOUGHT I WOULD SHARE THIS WITH EVERYONE TO MAYBE SAVE SOME TOOLS FROM BEING THROWN!

if you didn't close off the ipr valve air will never reach the other bank just a fyi. The high pressure oil system if tested on one side needs 10 min or longer to push the oil through the other side if there is a leak on the other side! if the leak is on the side your testing you fix that leak and retest to get the air to the other side.

I UNDERSTAND THAT I NEED TO CLOSE THE IPR VALVE, WHAT IM TRYING TO EXPLAIN TO HELP OTHERS IS THAT IF YOU LOOK AT NEWER STANDPIPES THEY HAVE A CHECK VALVE AND ONLY ALLOW YOU TO CHECK THE PASSENGERS SIDE OF THE ENGINE WHEN YOU PRESSURIZE THROUGH THE PRESSURE SENSOR PORT, I HAVE NOTICED THAT NOT ALL OF THEM COMPLETELY SEAL OFF IN THE STANDPIPE BUT A GOOD AMOUNT OF THEM WILL... FYI USING THE TOOL THAT WORKS THROUGH THE REGULATOR I WAS ABLE TO COMPLETELY CLOSE OF THE SYSTEM WITHOUT THE NEED OF APPLYING VOLTAGE TO IPR AND RISK DAMAGING IT OR USING A SCAN TOOL TO CLOSE IT OFF, PLUS I COULD CHECK THE PUMPS OPERATION WHICH I HAVE NEVER BEFORE SEEN A TOOL TO DO THIS UNTIL NOW

When you test through the icp port on a 03 to 07 you are testing the entire high pressure system with no check valve stoping anything! The check valves never close and not allow air to fully pressurize the entire system ever! The check valves are pulse arresters only. I'm not trying to debunk your analysis but it is not correct sir. If that happened to you the check valve in your standpipes where bad! It doesn't matter what point in the high pressure system I'm testing it will test the system at a whole!!! I don't want members here to get the wrong information this is why I posted here!!

which standpipes did you have? 2005s came with 04 style(square) or 05+ style(hex). Both have check valves but in different places.

The 05+ standpipe can be easily disassembled and you'll quickly see it's not what you think it is . It's not for drain back purposes but rather to subdue the oil pulses from the high pressure pump
