    Loving my E85 right now

    Yes I had a lifter collapse at about 277k miles. I reprogrammed mine from about the time it was new to run as a V4 for longer.

    Loving my E85 right now

    You will get much better fuel economy if you advance the timing. I reprogrammed my 2010 and have gotten 14.5-15mph on E85 trips on the highway. Also with the increased timing you will make more power thus allowing the 4 cylinder mode to be active longer.

    Had another lifter collapse at 281K, Now running it as a 6 cylinder

    I know how to do it manually but I am not putting gas in it very often since barely driving it.

    Had another lifter collapse at 281K, Now running it as a 6 cylinder

    I am waiting for my slow ass house to be finished to change out the cam. I had one lifter fail at 278k so I swapped out the failed lifter but was left with a tick since the cam must be damaged. I drove it a little as a 7cyl then just put the rocker arms back on and said screw it drive until...

    Lifter tick help will mmo or motor flush help?

    I have not replaced the cam yet. I am waiting for my home to be finished that will have a much larger garage. I will just put it back factory. If it lasted 278K miles before I am not worried about the AFM.

    Lifter tick help will mmo or motor flush help?

    My 2010 collapsed a lifter at 278k miles, I pulled the head and replaced the lifter but it had damaged the cam so a lesser knock but still a knock after replaced. 280K now so 2k miles on the knock and it isn't getting louder. I know it isn't an exhaust leak since I can pull the rockers off...

    help choosing a radiator

    When it came to Radiator and motor mount they were the cheapest around too. They use to have a clearance section and loved it, but they got rid of it.

    2022 6.2 High Country - Low Oil, Likely Blown Motor

    Even back in high school a friend had one of those late 70s big boat buicks or oldsmobiles he kept getting a oil pressure warning light when he turned corners. Him and his dad finally changed the oil and what came out barely filled up a 1 quart bottle. So even with that little he still had...

    Cruise control

    After an accident on mine the cruise would not work and also the brake lights where not working!!! So please make sure you brake lights are working. I replaced the brake switch and it still didn't work, it ended up being one of the little wires in the harness that goes to the brake switch...

    2022 6.2 High Country - Low Oil, Likely Blown Motor

    Still as I said the pickup should be on the bottom and work with even a few quarts. My Vette I had to drive it a lot and didn't check the oil and it was below the dipstick and still had oil pressure it was over 2.5 quarts low on a 5 quart pan.

    2022 6.2 High Country - Low Oil, Likely Blown Motor

    Even if you were down to 4 quarts it should of had oil pressure. Unless chevy put the oil pickup location like 3 inches from the bottom of the pan. My Gallardo holds 10.5 quarts and the fill procedure is to put in 5 quarts and start in then add the rest, yes dry sump but still you should have...

    Had a lifter collapse at 278k miles

    Yes i know but I wasn't gonna pull the cam now my home I am building will be done in about a month and I will have more room to work on it then. I will just drive it with the tick, you cannot even hear it inside unless really paying attention.

    Had a lifter collapse at 278k miles

    So I pulled off the head and replaced it... either the crappy lifter I put in is bad too or the cam has an issue. It is still ticking, not like when with the collapsed lifter but it is ticking. I pulled the rocker off of that lifer and confirmed it is the one I replaced, cylinder 6. I am less...

    Still can't get Adaptive Cruise on Z71 in 2023 but you can on a work truck..

    Since I sold my 2021 Z71 I have been looking at something else to get. I was looking at regular cab, regular bed work trucks since I like the short length trucks. I was building it and adaptive cruise is an option $750. I don't know what constraints currently if you can really get it but it...

    Anyone Use E15 / 15% Ethonol in their 5.3L Engine?

    I haven't touched it in years and the laptop I used that has my program died. I even played with increasing timing using 93 to get better fuel economy, it did improve but not enough to offset the increased cost of 93 vs 87. So I just stick to 87 and E85 when it is not super expensive. Last...

    Anyone Use E15 / 15% Ethonol in their 5.3L Engine?

    I used HP Tuners and did a lot of playing with it. If yours is not flex fuel you are running way way lean when you put E85 in. Ethanol is not as energy dense as gas and the engine needs more fuel. With mine I increased the timing significantly when running E85 that is what got the efficiency...

    Traded in my 2021 Z71

    I paid $63,675 for it in Dec 2020 and I got $64,000 on the trade in, it had 24K miles. I got a new Malibu for my wife since she drives 26 miles each way to work I didn't want her just running up the miles and using a bunch of gas and damaging it..... No more car payments for the time being...
