Compression numbers
Hello everyone. After almost a year I am still trying to hunt down this partial miss. I thought it was a lazy lifter, so I replaced all 16. Also checked all the push rods, nothing bent. Most recently I did a compression test, and here you will find the numbers. The injectors are only two years...- OldIron82

XL to XLT Lariat cab swap!
Hello all! First and foremost I apologize if this thread is in the wrong place. My 89 F350 ( 6.9, zf5, BW1356) cab is a plain Jane XL, with manual windows and door locks, cruise control and AC. It’s heading for inner and outer rockers, cab corners, and some floor patches. The driver floor is the...- OldIron82

Can’t find miss, please help!
Wow thank you for all of that information! When I replaced the lifters, I checked all the pushrods on a flat table, all rolled perfectly. No bends. How can these valves be adjusted? I thought hydraulic lifters took up any lash no matter what? Trust me, I am well versed in junk new parts out of...- OldIron82

Can’t find miss, please help!
What is the best compression tester to use? I’ve read some nightmarish reviews about the most popular one on Amazon, saying it doesn’t have a check valve to hold pressure, or something like that. I can already tell you the second cylinder from the front on the driver side is the culprit. I have...- OldIron82

Timing is right on the money, a very reputable member here timed it for me perfectly. Cold advance has been unhooked for quite some time now. Yes I kept driving to my destination that night. The next day it ran like nothing happened, and within a few days this partial miss appeared.- OldIron82

Can’t find miss, please help!
Hello all. I’m about to rip my hair out. My 6.9 idi… Ive been dealing with this intermittent slight miss that has varied in intensity since January of this year. Right before this began, I installed a new 100cc injection pump from a very reputable shop who shall remain nameless, I don’t want to...- OldIron82

Lifter replacement
Glad I seen this thread! I’m just about to order a set myself! About Laine D’s question about new pushrods... what’s the consensus on that? I reused the ones that were in the engine (6.9) but I used 7.3 rockers. So I currently have a new R&D bigger cam, original lifters and rods, comp 910...- OldIron82

Lazy lifter & partial miss
I wouldn’t say it changes with RPM, it’s simply more “masked” at a higher RPM. You really can’t hear it over 2000 RPM but you can feel it doesn’t have the power it should. From idle to 1200-1500 it’s very pronounced. Sounds like a compression release Jake brake on low. It’s almost a dead miss...- OldIron82

Lazy lifter & partial miss
Wow. Ok that’s pretty much spot on what I got going on. I’m sooooo happy I took the time to delete the slip fit on the turbo and installed a quick disconnect. Still not happy about ripping everything apart but as I said before, I’m over it. It is so annoying to drive I just gotta go nuclear and...- OldIron82

Lazy lifter & partial miss
Hello everyone! After years of slow progress I finally completed my 6.9 and have it installed in my 89 F350 cab and chassis dump truck. ARP studs, injectors, cam, 910 springs, Bull Moose, ATS 093 with wicked wheel 2 and the big exhaust housing with the 3” slip fit I installed a quick connect...- OldIron82

Big radiator in place of small?
Hello all. I did something very stupid tonight. After 3 years, I lit up the 6.9 for the first time. Unfortunately I forgot to tighten the fan and it came sailing off and took out my brand new radiator. Spectra CU1165. Things are not good financially right now and I can’t afford to replace it...- OldIron82

Someone had their hands here?
Hello all. Dropped the zf5 tonight in preparation of the 6.9 swap (yes the one I’ve been doing for 3 1/2 years now) and I’m a little surprised by what I found. The throw out bearing is DONE, as I knew by the noise when the clutch was depressed. The input shaft however, looks in very nice shape...- OldIron82
