Hello, I purchased an LBZ with 200k on the dash. Drove great. Until it didn’t, low coolant light came on and now I can’t keep the resivoir full. I’m talking, fill it all the way full, drive 5 miles and it’s empty. Truck is hood dumped, so i’d see the coolant “splash” on the windshield if it was burning it. No white smoke, or smells. truck gained the smallest ammount of blowby since i noticed the coolant loss. Not sure if it has anything to do with it, but the PCV re route “mists” pretty bad too, but it doesn’t have a smell. Oil on the dipstick is not milky, truck runs and starts up fine you’d never be able to tell until the coolant gets low and it starts over heating. I’m kinda lost, and trying to create a list of things it could be. Thank you for any insight you can give.

Hello, i have a 2006 3500 lbz.

I’m running into an issue where if i’m pushing the truck hard, it will throw p0087 sometimes throw it into limp mode for 2-3 seconds then return to normal power. I have a tuner i clear the code with when it comes up and it’ll only return if i’m heavy on the pedal. Recommendations on where to start diagnosing it? what are the possible issues? Thank you!
