Removing the spark plugs and wires. they are originally 9.5in long but the new ones I got off of rock auto are 12.5in long. Is that fine or should I return then and get 9.5in long?

      Fluid Change Questions

      By Chuck FB · Posted

      I know when I was looking around last year to see if someone handled Amsoil gear oil to buy at the retail level which of course means full price. I found an independent shop that works a lot on GM/Duramax pickups and they did not bring in the 75W-85 as they just stuck to the 75W-90 for the front and rear as a standard practice for the HD trucks which makes sense anyway for the higher hp/torque diesel and pulling heavy loads in four wheel drive. I haven't changed my diff oils yet but still plan on using the 75W-85 for the front diff as I highly doubt I will be beating on the truck and figured for my use type the bit thinner oil would be to my benefit for the winter for that slightly less drag. Very different weather here all winter vs northern Washington near the coast, that's for sure.

      Oil Consumption

      By Chuck FB · Posted

      Ok that confirms the extra quart theme they are still going with which must mean they have noted some initial use more so then some engines and probably the bigger factor in all of this probably isn't the engine so much as its the insane distance or OLM that lulls a lot of the driving public into driving their new vehicle off the lot and not even doing one short interval oil change because the manufacturer doesn't say different and if the dealer follows that logic as well. Selling the rarely needing to be serviced concept seems to go over well with the public that wants to get away with as little as possible for dollars spent on the vehicles maintenance and I bet there are 3.0 engines just like other vehicles out there that never have their oil checked by the owner which goes back to why they probably felt the need to add that extra quart to avoid a costly theme.    Speaking of cutting filters open, it was probably over two years ago now that a youtuber who buys vehicles to do longer term reviews and pulls a fifth wheel through the mountains of Colorado on summer trips and that becomes part of the testing. Anyway he had a GM HD with the 6.6 gas and a Ford 250 with the 7.3 gas at the same time and of no surprise the Ford had more power etc but somewhere along the way in the few thousand miles he put on the truck, he changed the oil and was seeing glitter and cut open the filter and yeah, things were not looking spectacular. The truck about that time or soon after seemed down on power compared to what it had been and then threw some engine code, I expect the cam/lifters were failing and so he brought the truck back to the dealer and made some deal to get out of it as he knew it would sit for months waiting on a new engine as they were so backlogged at the time. He kept the GM for some time after that using it exclusively until he sold it after buying his next vehicle to do a review on. Definitely the filter can tell a story when things are starting to go sideways, but it would be a sickening feeling to cut it open and be faced with an ugly mess like that and be running a magnet through the pleats and the oil on the dirty side of the filter and see all the fines sticking to the magnet.    The dealer may have some ideas based on experience as to where that coolant smell is coming from, I would imagine if they can't find it but its smelling they would put dye in it to they could give it a run cycle and use the black light to see where it pops up, if its a hose connection, water pump, rad or even a head gasket etc.

      charm.li (website) has the vehicle-specific diagnostic procedure for that code, you can use to find what the cause of it is.
