    DTC P0251

    Having to replace an optic sensor in a BRAND NEW ip or even one you buy that is a rebuild is completely wrong. Buy a long block engine and have to replace an oil pump or oil pan? No. If a new ip is faulty and has to get replaced by a shop- the distributor pays for a cut portion on labor...

    Coolant flow

    CHECK OIL DIPSTICK!!! Since no exhaust gases in coolant and no visible leaks only other inside the engine possible is into crankcase. Oil turns to a milk like with water/coolant in it. Is so DO NOT START AGAIN.

    DTC P0251

    Is this with that brand new ip? And no- long potentially danger trips are not advisable with a 251.

    Information on the ATS Turbo Kit

    Don’t replace them just because it isn’t the most common- heck the common gmx turbos are not very good. The factory crossover is a p.o.s. So unless building custom headers to get to the turbo flange, I say run what is there. 3 psi cruising at steady speed on freeway can be...

    How do you all get 6.2s to 300K miles

    The set of injector return lines from Leroy is fine. I bought a set from him. I used to get the line by the foot from a Mercedes Benz dealership for the om603. It just pushes on without any clamps, but it’s a bit more expensive. I think they last about the same amount of time.

    What did you do with your GMT400 today...or yesterday....

    There are aftermarket tachometers.

    How do you all get 6.2s to 300K miles

    We don’t know the best boost numbers for your engine because we don’t have specs on that ATS aftermarket turbo- but it is a really small turbo, I would estimate same size or smaller than the gm3. When the gm3 was added to the 6.5, 10 psi all day long was a safe range. iirc above 12psi is when...

    How do you all get 6.2s to 300K miles

    Im seeing two different smoking situations here. Cold start up it’s more blueish. What doe that smoke smell like? I am assuming it that is oil and the overheating issue from before beat up the rings especially in cylinders 7&8. Then the age of the valve guide seals are probably letting some...

    Just arrived, howdy

    Yeah- the b12 trick is usually for stuck rings not valve guide seals. Yes a bypass filter is a good thing. The one mentioned or the Frantz are both good choices. Yes to the compression test. My suggestion is do dry, wet, and cylinder leakdown tests to all at once. Write down the info in a...

    FSD Fuel Solenoid Driver was one the aftermarket started using for a while. GM used PMD

    Sure not common. Yeah carry the spare

    Blow by

    Yup- just keep running it. You just sped up the process with that overheat issue. Keep it in check best as possible. 200 is ok 210 watch the gauge more than the road 220 pull over& let it cool back to normal. Not a bad idea to pull & clean cdr. Clean upper. & lower intake. Take pics as...

    Chinese 6.5 block

    We hope the rig does awesome for decades to come. Have your grandkid pop on here too whenever age appropriate to keep grandpa’s truck rollin. There’s just something special to a family rig.

    Motorhome Lift Pump

    I wouldn’t expect to feel much of a difference. This is more to keep the ip healthy.

    Gm engineer- talks alot about trans so this is here but really- learn it’s everything

    Well if it is v8 with 6 speed- so it would need the afm delete if not done yet. If you can diy the delete it isn’t too bad. But paying a shop to do it is pricey. Imo if you diy: pull the engine down the new cam & lifters with plugging the oil feed for afm and different cover. The ecm can be...
