You still have 4 weeks. Well, less than 4 weeks now. We are gathering in March. 21-23 of March to be specific.

That height sensing valve is a must remove item in my opinion. It is only there because the trucks but mostly the Suburban’s couldn’t pass the obstacle avoidance lane change at high speeds. Slamming on the brakes while trying to steer caused the rear brakes to lock up and the vehicle to spin. So...

That is so true! My son drove all of my MV’s to school at least once.

Since they aren’t dragging due to pressure. I would suggest that you invest in some new calipers sometime soon.

I figured that but wanted to point out a really simple thing just in case.

Do you have the CDR (Crank case DepRessurization valve) fed in front of the turbo or under pressure?

Delphi HFP906 is the correct lift pump part number. I just put one on one of my engines a few weeks ago. Besides somehow not getting the pump installed with the push rod against the pump arm. You could actually have a bad pump right out of the box. What about the supply hose to the pump. Did...

1/4” ID is the hose size from the filter to the IP. I like putting a lawn chair pad over the radiator and front of the engine to lay on.

The boost gauge will be on the intake side. It sure reads as if you have several small leaks. There are ways to check for leaks. Here is a video of doing that: Since I think you have the center mount turbo. You can pressure test through the turbo and into the 3 piece intake.

After the hose mentioned above is replaced. The next most likely leak is the o-rings on the throttle shaft. They probably won’t leak with the engine off or cold. Shining a light on either side of the IP with the engine warmed up and running might show you the leak. That is how 3 of mine have...

Great!

I have removed all of them without issue on several trucks in the past. However, I can not remember if I used the socket, a combination wrench or something else. Have you tried moving the shifter to maybe get clearance?

Inside the tank the fuel pick up could have rust holes. The hose from the pickup to the fuel pipe could leak in air. The hose between the pipe and the fuel pump could be the issue. The fuel pump could have a bad diaphragm. The metal pipe from the fuel pump to the passenger side valve cover could...

Did you lock your front hubs in for driving in the snow? I agree about the filter not causing a mpg drop. There is more drag somewhere. Hubs locked, sticking front caliper, parking brake hanging on and similar.

A lot depends on the off set of your wheels. Here is a video showing stock fenders, kind of cut fenders and then fenders cut even more. I would suggest mounting the front wheels and tires. Then lifting each side of the front axle as far as you can and then try turning the wheel lock to lock...

GM went to the Korean built reduction drive starter around the time they came out with the 6.5 engine. It was cheaper to build and lighter. Good and Good from their point of view. The military supply chain had to switch over as well. I actually like the old heavy straight US made Delco...

That is a good question. I will have to go look at my stash when it warms up a bit. Practicality wise I don’t remember any notation in the TM and there is no difference that I can think of in function. Just clean them all, put in the bulbs and test before you install in the truck.

Civilian screws are what you need. My problem has always been the plastic clip in thread inserts. They don’t let the screws hold the light in place. Putting a nut and flat washer on the engine side of the adjuster bolt works wonders. Yes, you will have to use two hands to adjust your lights...

Here is a video about the starters, brackets and bolts: You need the bracket. Don’t try starting the engine again until you have the proper one installed! Yes, that sounds over dramatic. I have 2 blocks that have the outside screw hole broken off. The block just cracks off out there. I got...

Removing the resistor in the glow plug circuit is a fairly common practice. It does have a few down sides which you mentioned. Here is a video about bypassing the resistor issues.
