    How do you all get 6.2s to 300K miles

    @nycxjeremyy I'm curious... you are running a 4l60E. what are you controlling it with? keep in mind that the 4l60e is the weaker transmission. that 6.2 has the torque to blow that trans up. you might look into at a later date getting a 4l80e or having that 4l60e built up to withstand the...

    How do you all get 6.2s to 300K miles

    Oil weight has a lot to do with your climate. 5-40 is more common in colder areas where 15-40 in hotter climate. use good oil not the cheapest on the shelf will also help. keep the boost down under 12psi and as close to 0 as possible when cruising will keep your engine happier. as for...

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

    Strangely enough while I was replacing the blower resistor, the LP randomly decided to turn on. I had just finished up washing off the engine with the power washer so I pulled the connector to the OPS and sure enough there was moisture on the pins. blew out the sensor and connector. the...

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

    Found it. did some searching on the innerwebs and apparently it was for a diode back that has something to do with 4x4. one wire comes from the brake switch and another to the 4x4 switch, rear ABS and TCM. all the wires are there but no diode back inside. this truck is a 2x4 so I guess...

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

    Did some other minor repairs on the 93 prepping for the trip next weekend. my blower quit working on medium speed. checked all the relays and finally deemed the resistor at fault. got that fixed. while I was in there I found this little grey long box of sorts with two pins as if something...

    6.5TD motorhome starting problem

    for OBD2, you'll need to find the fuel pump relay under the hood and jumper pins 30 and 87. the pump should run iirc. for the older OBD1 systems there is a pin in the data connector you can apply positive power to and turn on the pump, that won't work for yours. other than that, find the...

    My 93 having a mysterious tapping or knocking under acceleration that comes and goes

    Wonder if I should just try retarding it a little and see what happens. iirc advancing is moving the top of the IP towards the passenger fender. this is what I did previously as you can see my blue mark is slightly off (IP turned counter clockwise) correct me if I have it backwards.

    My 93 having a mysterious tapping or knocking under acceleration that comes and goes

    since driving the 95 around yesterday and today, I now realize just how much louder the clatter is from the 93 with the newly rebuilt injectors. figured I would look at timing to see if it needs to be adjusted. took a gander at the IP timing mark and looked for the center timing mark on the...

    My 93 having a mysterious tapping or knocking under acceleration that comes and goes

    Well got the engine washed up and free from oil and grime. pulled the dipstick tube off the oil pan and pukied the end up with some right stuff and shoved it back in the hole after cleaning it and the hole out real good. while I was underneath, I know it needs front shocks, but the bushing...

    Need help 6.5 chevy

    If no go, then you need to make sure that when you installed the engine, you have all three grounds with a solid connection on the intake near the passenger side rear head. they are usually right next to the trans dipstick tube. if you have a scanner, connect it and make sure you can...

    Need help 6.5 chevy

    Welcome @racerallmine verify you have fuel pressure from the LP and the air purged from the filter. then make sure that when you have the key on, the fuel shut-off solenoid has power at it's connector. if all is good, it will take quite a bit of cranking to see fuel at the IP lines at...

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

    In other news, I've driven the 95 here and there the last couple days and noticed right away of how much LOUDER the 93 is now with the newly rebuilt injectors in it. it's noise level I think now exceeds that of an old 12 valve cummins!! I wonder if I need to revisit timing adjustments since...

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

    Pulled out the pressure washer today. soaked the 93's engine compartment down with some degreeser and gave it a good bath. Man there was a lot of crap in the driveway!! got it all cleaned up now, I might try to pull the oil dipstick tube from the pan and seal that up since it's blowing oil...

    Transmission overheat trouble

    you want to verify continuity on the trans temp wires from the trans connector up to the IPC also verify there is no other pins that also have continuity with that same pin as well as no continuity with ground. I'm thinking that there is either a short to ground or a couple of the wires in...

    My 93 having a mysterious tapping or knocking under acceleration that comes and goes

    I found these two kits on the jungle site. I think the one from badger diesel is the one that doesn't need the clamps. https://www.amazon.com/6-2L-Diesel-Injector-Return-Chevy/dp/B079H5XCZ9 https://www.amazon.com/Delphi-7135-274-Fuel-Injector-Installation/dp/B002M1D4PI

    Transmission overheat trouble

    Disconnect the harness from the trans and see if the trans gauge is still pegged on hot with the key on. Now key off and disconnect the IPC and probe the data pin in the trans connector for the temp to the pin in the IPC connector. while ohm testing , leave the probe in the trans...

    97 4L80E dropping out of TC lock up

    adding a bottle of lucas trans fix will thicken up the fluid some and can tell you if things are worn inside. if the trans shifts better and stays in 4th for longer with the lucas added, that is a good give away that its time for a full rebuild.

    Eratic behavior from an 85' 6.2 (more below) requesting help please (Two vids in one)

    I prefer Mobil 1 5w40 synthetic or rotella t6, but with leaks that gets expensive. lots of folks run the wally world cheap 15-40. it all depends on how you drive it, or work it. how many miles you go between changes. if you do the changes every 3k miles, regular old dino oil is fine so...
