hey fellas,

 

i found this on another forum and thought you might want to check it out.  it sounds a little extreme, but makes some sense.  it is supposedly a solution to the 'pinging/knocking' ordeal.  

 

i do not know from experience if this works, but thought i'd throw it out there for you guys to check out and follow up every once in a while to see what happens.

 

Here it is...

My 2000 5.3 has had this process done twice & did not make any difference whatsoever for the cold start knocking that the TSB from Chev refers to. Mine is not a ticking,clicking,tapping,pinging noise at all. The knocking sounds like a diesel engine on startup & will last from 10 seconds to 2 minutes upon starting it after sitting either all day or all night in any temperature. The knocking will turn heads 200 feet away & had my neighbor asking was that my truck that made that noise! It didnt knock for 17K miles & then started when temperatures were in the teens. Now it does it in any temp & every day in the a.m. when first starting truck & after work when starting truck. The #028 service bulletin refers to piston slap noise & GM considers this noise normal & will NOT do any repair whatsoever.

I'm not a mech. but found this--------------------------------------------------------------------------------

I posted about a week ago about this but I don't mind saying it again. I was getting a tapping sound from the engine when I first cranked it up, and my accelerator pedal was sticking until everything got warmed up. My good friend works at the local GMC dealership and told me that this seemed to be a common problem with these model trucks. A buddy of mine told me how to fix it. He said to pull the air intake tube going in the top of the engine. Spray some carburater cleaner in the opening and let it sit for a few minutes. Clean residue off and replace the tube. Crank it back up and all should be well. It worked like a charm and now I do it every oil change as a preventive maintenance item. Takes all of five minutes and no more tapping and sticking pedal!!!!

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
