6.0 Engine Knock

I posted earlier about a ticking noise at an idle, on my 2001 2500HD with a 6.0 I tried to figure out if it was the engine or transmission but the flex plate inspection cover won't come off with out dropping the exhaust, so now I was wondering if I can unhook my knock sensor and run it to see of it rattles more ......

i would guess unhooking the knock sensors would reduce knock and shaking if there is any. Because it will make the ECU retard timing. Alot of 6.0's have a rough idle sometimes tunes or new intake and throttle body gaskets can help, MAF and throttle body cleaning too. But overall that the nature of the beast :smoker: . If its a ticking sound some good leads are, CSK (search if tons of info), an exhaust leak, or valvetrain--lifter noise.

 

try your best to describe the sound u hear

+1...a friend of a friend is a Chevy tech and did a complete run through on my truck when I thought the idle was getting a little rough. I take very good care of my truck and he found no system issues at all. His comment was the same. After about 55,000-60,000 you'll notice the idle get a little rough but it should/will not effect performance. Aside from the idle I agree, performance is still great and truck drives very smooth at 78,000 miles. "Nature of the Beast" is correct my friend!

I was told my rough idle was plugs n wires. They also said that could help with the CEL resulting from random cylinder misfires everytime I get on the highway and do 60 mph...

I'm not having a rough idle issue I have a tick or knock that I want to diagnose as an engine or transmission issue, so If I can disconnect the sensor for a minute to see if it get worse or not..

There is probably nothing wrong with it. There aren't many 6.0s that don't tick from somewhere.

Amen to that. Mine makes a few goofy noises all the time. But each time I turn the key it fires right up and gets ready for its torture test.

you can unhook them with no long term effects but i bet you will get an SES light and a code. But once you hook them back up and clear it it will be back to normal. The knock sensor connector is on the drivers side of the intake clipped on the rear upper corner it will be black and have blue accent pieces of plastic.

 

but i really doubt you have a detonation problem ticking is 99% of the time an exhaust leak or noisy valve train.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Z45 · Posted

      The oil filter has NOTHING To do with oil leak. GM sources parts from 1,000's of vendors and as with anything mass produced, flaws are unavoidable.    Putting a larger oil filter will do nothing but satisfy emotions. The OEM filter is designed for the engine and perfectly capable of handling the demands on the engine. Oversize oil filter could result in reduced flow and overall lower oil pressure.

      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.

      Diesel hit $6.00 here today at the truck stop.   Payed $2.79 for E85 today too.
