    What could these codes mean?

    These two are usually from air in fuel, install clear line on return out of injection pump and observe after it's been running awhile.

    Going mechanical with a Moose Omega Marine IP

    Good work. I knew when I saw your videos of the acceleration that you'd take the new record. My truck hasn't run in 4 years, lots changed in my life so everything has been in storage. Those are some awesome numbers.

    96 k2500 db2 glow plug issues

    Cummins = Tractor engine. I can't stand them either in pickups.

    AC Delete Pulley Issue - IT BROKE!

    That bracket and pulley is off a non-ac 92-95 setup, specific bracket. I have one and noticed what you noticed in that it looks like a vacuum pump drive without the vacuum pump pod on it. I would think you'd be able to use the vacuum pump in place and remove the pod. You'd have to find a freeze...

    Going mechanical with a Moose Omega Marine IP

    I know when I do another mechanical 6.5 engine and want dual stats I'd take the shortcut and get one of Kennedy's modified outlets and brackets for the MFI engine.

    Head flow info

    The stock valve sizes for all later 6.2 and 6.5 NA and Turbo engines (including P400) is 1.810" Intake 1.535" Exhaust. We've also flowed a set of 82 6.2 heads equipped with the 1.653" Exhaust valve, with good results.

    Head flow info

    I'm done with the rollers for the most part. It will be results based on CFM to Lift values and percentages compared to OE. Gains are subjective to bolt-on hardware. Engine Dyno results would be great from stock head to modified, but this won't happen until I get my own engine dyno in house...

    Head flow info

    Used castings are risk. I don't even mess with used heads for builds because about 75% of them are cracked, all the builds end up with new heads (which really increases the cost of the build) but it is what it is. I think a customer would send me some heads they think are crack free, only to...

    Head flow info

    These gains are strong gains over the stock castings. Seeing this work that Chris is doing on his grinding is absolutely impressive! His grinding and machining methods are consistent. There was one cylinder where an experiment was made on the grind to see if the grinding would help or hurt...

    E C M Reflash ????

    ECM Flashes. I can do 1996+ ECM Flashes to stock calibration for situations like this or replacements. They all require the VIN, which get's programmed into the ECM. With the VIN I get the correct original calibration for the vehicle for it's options. 1998+ have to do the Passlock Security...

    6.2 intake part numbers

    Yes, the 2nd intake manifold down is the one you want, not second image on the page.

    6.2 intake part numbers

    This is the correct manifold for your application. Bolt on and go: http://www.uniquediesel.com/intake8487.html You can buy it on this page: http://www.uniquediesel.com/bolton62.html It will be the 2nd one down. I have several in stock right now. John

    Trouble with the Optimizer 6.5

    You're saying that with the heads you've worked with that the intake valve is opening prematurely and conflicting with the piston during the intake stroke. I see two possible contributors. If cam timing is correct (controlled by the timing chain set) that the minimal recession of the intake...

    Trouble with the Optimizer 6.5

    Good catch on the floating valves. Cylinder #7 shows this.

    Trouble with the Optimizer 6.5

    Thank you! You just made my case! What in the world is wrong with something that lasts for 200k miles. Nothing's perfect, the TTY bolts do fail, sure. I've seen soft ones made that wouldn't hold torque new. Stuff happens in the production word. Just saying that a person doing head gaskets will...
