    HARD KNOCK AFTER LIFT PUMP REPLACEMENT

    I’ve also heard both a valvetrain tick & an injector knock with these engines. It sure sounds like you have a valvetrain tick listening to your vid. Just my .02

    HARD KNOCK AFTER LIFT PUMP REPLACEMENT

    Sounded exactly like my engine when I had a brand new hydraulic lifter that collapsed. I would pull valve covers and see if you can depress any of the rockers with your hand. If you find one that depresses easily, bingo. I think the lift pump change may have just been a coincidence, and not...

    how to go on with my E4OD

    Running a new torque converter dry doesn’t do it any favors either. You were supposed to dump a quart of atf in there prior to mounting tc onto transmission. Like already mentioned, removing a trans line might be the best way to drain some fluid from transmission.

    Money Pit #2 Won't run.

    With those test results, I would be pulling that engine out for further diagnosis. Sounds like it may need a full rebuild, but I would check out those cylinder heads first.

    6.9 cyl head upgrades/mods

    Did you take the cylinder heads into a machine shop to verify that there are no cracks? I would if you haven’t

    Yeah, the FBI planted that in your truck LOL

    Old 6.9 idi

    I would go sealed power. Stay away from enginetech.

    Looking at a truck. Opinions?

    Ask him where the injectors came from. He likely put cheapo reman injectors in it, so it’ll probably need new squirters and injection pump from Conestoga diesel or typ4 aka Russ. White smoke does sound like a timing issue, or crap injectors that are dribbling bad.

    Gunk on injector

    That’s somewhat normal. Turn on the wire wheel or brush it off.

    Cold start issue after new injectors

    Ultra gray rtv on the IP tower. Sealed many without a leak. I was able to take a paint pen and mark both gears. Using a flashlight, you can mesh the two gears together and see your paint marks to verify it’s correct. Works like a charm for me.

    Should I switch to synthetic?

    When your oil turns black, that means it’s doing it’s job. Wouldn’t worry much about it. These aren’t formula 1 engines lol.

    Timed my truck tonight

    This is a good point. No matter how good you think you are at timing an engine by ear, you don’t know squat until you actually hook up a meter. The whole “timing by ear” thing really ain’t worth a damn.

    Valve starting to stick

    Man, that stuff normally works damn well. Anyways, glad you got er running good.

    How many qts of mmo did you initially put in?

    6.9 block work

    I would bring the crankshaft into a machine shop and have them take a look see. They might be able to turn it and remove those problematic areas on the crank.

    Should I switch to synthetic?

    Here’s my reason for running synthetic in my Jeep & wife’s suv. It’s more expensive, so it must be better. Nuff said LOL

    Should I switch to synthetic?

    I don’t believe synthetic oil in an engine will net you better fuel mileage. A thinner weight oil might. People mainly run synthetic oils when they want to achieve longer change intervals, as synthetic oils tend to hold up a bit longer before breaking down. I would run it if you want, but that...

    D60 3.55s stock size tires or 4.10s 33 and up tires

    You are going to want 4:10’s with those 33 tires. Just regeared my Jeep that I bought with 33’s and a 3:55 ratio. It kind of sucked to say the least. Seemed like the engine was always lugging around town. Just had it regeared to 4:10’s and it was a night n day difference. Well worth the $

    changing the block... again

    That’s bad but mine were a lot worse than that. Goes to show you when you got worn valve stem seals. This is what happens.

    changing the block... again

    That is one clogged up port. Looks like the driver never put there foot in the throttle either. These engines will clog up like that if they aren’t run hard every once in a while. And bad valve stem seals make it worse. You should have seen my engine when I first tore into it. The PO drove it...

    Porting idi heads

    Like mentioned, porting these heads won’t do much good imo. They flow quite well in stock form, and doing so won’t net you a power gain. Only thing that does a damn bit of good in regards to hp is a turbo on these old engines.

    Valve starting to stick

    Sounds about right for a jasper rebuild unfortunately.

    rings?

    I’ve had problems with enginetech quality in the past, specifically pushrods. I would go with sealed power, as their specs are always correct and build quality is superior.

    Project Jerry

    You can buy dynomat brand insulation for $50 a roll, or go to Home Depot and buy duct insulation for $18 a roll. And it’s damn near the same stuff. Used it on my yj when I put new carpet in er. Just FYI ;Sweet
