Exactly how can it "move away from the heater element"? The block heater is way below the coolant level and the water pump shouldn't be pumping air through the system. There's nothing to go in the area around the heater element so it's not immersed in coolant.

The owners manual is an excellent source of information as to what fluids to use for the various parts of your vehicle. I find using a small pump works well for filling them up, vs trying to use a tube or directly trying to squirt fluid in from a bottle or squeeze pack of oil. Don't over-torque the plugs when you put them back in.

2 engine replacements, $3K in handling and suspension, it sounds like you beat on the truck... Anyway, check the exhaust system, as it might shift a bit as you turn left & right, so you hear the exhaust, then shifts back over time so you can't hear it as much. Make sure all the bolts are in and tight in the exhaust manifolds to the heads and the up pipes to the manifolds. Also check oil level and what the oil pressure is when this sound is happening.

It would be if they even got a fraction of a MPG increase when using it. Even a small increase in MPG would help with EPA requirements, and if just having a bigger air inlet made a difference, they would do it, as it would be free for them.

1. towards the top right of the page, there is a text area with "Search" in it. Click/tap in there and type away. 2. indicate what specific vehicle/options you have

Yes, if you can lean over the engine enough, or have an inspection camera, or you might be able to use a cell phone camera to take a video or picture, you should be able to see if the orifice is plugged (which isn't likely). You would be able to use a small screwdriver to unplug it if it is, as it's just a small hole about 3/16" in diameter. It's not like the old rattle-can style.

never heard of a crankcase pressure specification.

Are you sure it's not coming from the top rear of the engine? Depending on what engine you have, it could be coming out there.

There will be a 0 mpg increase. If there were any measurable increase, GM would be including that intake setup on their stock vehicles.

When I first got my truck, before I fixed it, it would drive ok, but just guzzle gas, as it both had an exhaust leak, and low fuel pressure, so the ecm was dumping as much gas as it could into the engine. It shifted fine, but had no power (as the gas was being dispensed, but poorly, as there wasn't enough pressure to atomize it properly). I think the main things that fixed it for me were: -replaced fuel pumps (mine has two, only one is really important) -fix exhaust leak by replacing broken exhaust bolts and/or installing clamps for the ones that couldn't be readily fixed -replaced MAF and upstream O2 sensors I also replaced other stuff, but I don't think they had much effect (as in, they weren't an actual problem): -knock sensors -intake manifold gaskets -spark plugs -MAP sensor

You need to first find out where the coolant is coming out. Other parts are more likely to fail than freeze plugs, but if the problem is as bad as you make it out to be, it should be pretty easy to see where the water is coming out, or at least narrow it down to a spot.

Well, Eaton, who makes the G80, says you should put some friction modifier in, for the clutches the G80 has. GM says not to put any in. From what I've read on this and other forums, you can do either. Some people initially fill without, and then notice a bit of shuddering, and add some friction modifier and the shuddering goes away. You are the first person to suggest that adding friction modifiers causes them to wear out faster.

Recheck all the power and ground connections between the battery and the engine. By "recheck", I mean unbolt, clean, reinstall, and double check that bolt is tight. Then take your battery in to be load-tested.

I believe the O.P. meant to write "tune" instead of "tube". Well, the post makes more sense that way anyway...

You probably can replace the hinge pins. They wear. I know there are kits for the full-size trucks, and there probably are similar kits for your truck.
