    6.9 head studs

    The reasoning is the cylinders should be honed in the stress loaded condition they will be in when completely assembled. The machine shop will use 2" thick torque plates to mimic the cylinder head, then torque the bolts or studs to the proper specs and commence with boring and/or honing. This...

    6.9 head studs

    Hey Guys, I'm in the process of the rebuild on my 6.9. I am going to have the cylinders lightly honed while the block is at the machine shop. I am also going to install ARP heads studs. Should I have the studs installed prior to having the cylinders honed? Thanks

    Converting to cup style freeze plugs

    I looked at my block today and cleaned it up, no pitting. It was old sealant I was seeing. The sealing surfaces are really good. Maybe the disc plugs will be ok and put some good sealant on them when installing them.

    Converting to cup style freeze plugs

    I can't answer that, as this is my first diesel and first time to deal with disk style plugs. There is some slight pitting on the ledge where the disk style plugs sit. Worried that may be an area to start leaking. Then the engine would have to come out to repair it. I don't like doing things...

    Converting to cup style freeze plugs

    Has anyone here converted their idi to cup stylefreeze plugs? I saw a vid on YouTube using a hole saw. Looked like it did a pretty good job. The author said he "turned" down the OD just a touch to make a tight fit. I'm wondering how much material I should remove from the hole saw. I can turn it...

    Old 6.9 idi

    Hey guys, I looked at the used 7.3 style rockers I got recently. They came with the pushrods. Upon comparing the push rods, the "newer" ones are longer than the stock 6.9 pushrods. Looks like close to 1/8" longer. Suggestions? Thanks

    front crank oil seal sleeve doesn't fit

    How much too small? They are a very tight fit. I have placed balancers in my deep freeze for about an hour and used a heat gun/hair dryer to heat up the sleeve then slip it on. After getting the sleeve on I would let the balancer get to room temp before installing it on the engine. Some of the...

    Thanks for the input on bearings. Are there any upgrades or modifications I should consider for the heads? Heads are at the machine shop now getting checked out and vacuum tested. They are good and flat a 0.002 feeler gauge drags under the straight edge when I checked for warpage. Thanks

    Adding pyrometer to 6.9

    Hello, this is the location of the pyro on my 6.9 with an old Banks system. This is right before it goes into the hot side of the turbo housing. Is this location ok or should I relocate the pyro to the exhaust manifold or weld a bung on the exhaust pipe just after the manifold connection? Want...
