Little help..
Couple questions here..
First I Got a low end ticking sound, That I fear might be related to my exhaust leaks, But Im not sure.. I only hear it between 1300-1800RPM or so normally when the turbo is not lit I've got about 3 leaks in the exhaust, one in the welds on the downpipe, 1 in the welds from the downpipe to mid section, And another one to the Y for my duals..I want to chew out the guy I had weld it, But I dont think that will get me any where.. Anybody think this could be the culprit for the lowend sounds..? I still can make 26lbs boost with my AD code's and superduty turbo But this sound is driving me nuts.. Second question, How does one perform a compression test? a true one, not with a scanner, This would tell me for sure if my engine was tired/dusted correct? and in return guide me to look for a new engine and stop throwing money at this thing.. 3rd, I decided to pull the ICP sensor thinking maybe it was bad and could be apart of my problems( I still throw a P1211) under WOT this is with a 17* pump, and my AD's It did change Idle for a second, So I assume its still working properly ?? got a CEL, also Set my fuel filter light off, which I have plugged Seem like normal operation ? Mahalo for any advice -Patch |

Dont think there is any leaks at the manifolds, Looks clean there.. unless a really small leak could be doing this? I dont see any sooty areas around there
I was hoping It could had been just the exhaust leak.. well I guess I Can rule out the ICP sensor and Exhaust leaks the hunt continues .. How to check for a failing IPR ? Seems my "Idle Recovery" could be due to this.. Cruising along and come to a stopsign/light clutch in, Drops to like 300 rpm almost stalling..? than idles fine.. also are external UVC Harness interchangeable? I found a guy parting out his 96' and my UVCH connectors broke and are some what loose on the Passenger side, Was going to buy the harness from the IDM plug to the V/C's ? And assuming the compression test goes well, I'm planning on some glow plugs, And undervalve cover harness if needed.. Any suggestions on glow plugs? Should I stick with motorcraft? or are there options.. Thanks Cleatus12r, -P |

Good luck with your search.
As for glow plugs..... ONLY USE MOTORCRAFT ZD-11s. Any other brand is more susceptible to swelling badly when they fail and requiring cylinder head removal to remove the tip.

Have a clue what the ford guys will charge me? or should I try something online??
Got any thing for me on the IPR test?? I read Yours and Daves post about the UVCH connectors, I really need to get on that, But I'd still like to check a few things off the list for being a problem Thanks -P |

Like Cody said, only us Motorcraft GP's........they are pricey, but it wont cost nearly as much when a Autolite GP goes out and then breaks off in the head when you try to replace it. IIRC the GP's ffrom Ford are around 10-15 dollars a piece, but will not have to change them again for a long time.
For the IPR, have you scanned for any codes? Or ever had a CEL? |
