    Power Running Boards

    Ah, gotcha - I'll be sure the surface is super clean before sticking them on - thanks for the tip!

    Power Running Boards

    Truck came without any running boards - shorter passengers have been complaining that it is too big of a step to get in. I like clean the look of the truck without them, but the whining passengers got me thinking a bit more about it. After doing a bit of research I decided to order a set of...

    LZ0 Duramax engine to be revealed on 8/16

    Hmm.... interesting thought - maybe the oil consumption issue is related to the piston design. For example, let's say the oil consumption was due to a ring sealing issue - the excess blowby generated would bleed into the EGR system, and coke up the EGR and turbo VGT components. Are other guys...

    LZ0 Duramax engine to be revealed on 8/16

    Not surprising with a different piston - the injector would need an appropriate spray angle to match the new piston bowl.

    LZ0 Duramax engine to be revealed on 8/16

    I get that, but I think about it this way - if you're building many thousands of engines and you want to change the compression ratio from 15.0 to 15.2 it can easily be done with a piston change, or possibly even just some different cylinder head machining parameters. You don't change rod...

    Any foam cannon users?

    Personally, I am a huge fan of hydrophobic coatings - why they are not more popular is beyond me... Living on the We(s)t Coast I find it works great as I don't have to use wipers on the highway, visibility is excellent (the entire window is clear, not just the area that the wipers contact)...

    LZ0 Duramax engine to be revealed on 8/16

    Interesting - I thought the exact same thing - am interested to know why they went to a smaller steel piston and longer stroke - is there a long-term durability issue with the cast aluminum pistons? :unsure:

    Any foam cannon users?

    I love my foam cannon - am out of decent soap though - weak soap makes weak bubbles. The Mr. Pink suds up really nice for me, and also had a nice smell - going to look for a big jug of snow foam on special somewhere. I also just recently put a graphene coating on mine, and a hydrophobic...

    Shift to park..,,

    Interesting - will keep that in mind to program the trailer, thanks for the update.

    Shift to park..,,

    Did you shift the transmission into Park before shutting the engine off? Or did the transmission not allow you to shift it into Park until you unplugged the trailer connection? How did you exit the vehicle to unplug the trailer connection if you couldn't get the transmission into Park...

    New owner - take delivery tomorrow.

    Yeah, I hear ya - I don't want GM tracking my every location, and then selling my data to 3rd parties to make some extra $. Wow - sounds like they don't want to give you the option to 'opt out' anymore - it'll be baked into the price and become a 'standard' feature. I'm sure there is some...

    New owner - take delivery tomorrow.

    That's exactly the issue I am having - the truck recognizes the phone, but the AA doesn't 'fire up' like it should. I am assuming that you are NOT using the On-Star system? I am not a fan of the On-Star system, so I decided to cancel the service on the very first day - literally in the parking...

    New owner - take delivery tomorrow.

    Busy weekend - had to tear the garage apart to make some room for her - will do some more clean-up later. Lots of features on this truck that I am not familiar with - cannot seem to get my Android Auto to connect properly - will have to play with the settings/permissions a bit to figure it out...

    Oil ads

    I'd recommend it for older (higher mileage), oil-driven fuel systems like the 7.3L and 6.0L Fords, International and CAT engines with a HEUI fuel system. IMO - not needed in in a Duramax engine.
