OK- I am looking for a replacement set of wires for my NNBS Sierra. I have LLP's shorty headers that causes some purchase choice problems below. What is everyone using?

 

I am looking at;

JBA

Magnecor

Granatelli

 

Problem is the JBA's and Granatelli's only list to 2007 and the Magnecors say to use JBA's part number is you have aftermarket headers. If you have Part Numbers please post

 

Thanks

GM does millions in R/D for stuff like this, I'd use nothing else than AcDelco in my truck for something like this. Obviously other areas warrent using other brands, but I've never had a problem with AcDelco for tune up parts. :lol:

I understand the Nascar mentallity but with the LLP Headers the stock metal heat shields around the boots vibrate ever so slightly because the bigger diameter tubes just dont leave enough room for them. The stock plug boots are already starting to show brown hot spots from this after I took the boot off for 1 month. I am needing the extra heat protection the aftermarket wires provide. I am running the metal heat shields again but the faint ting ting ting noise irritates me and I was aware of this before I bought the headers. LLP recommends swapping for the Magnecors but I wanted everyones opinion first. Thanks

I like Aurora Electronics ignition wires. Good quality wires last longer in demanding applications.

 

A feature of their wires is the custom build availability. Unlike many that have a "universal" fit or a "finish it yourself" style wire set, they can supply their standard OE fit sets with different plug boots for header applications, if necessary. On a 454 (for example) it is advisable to use a 45 degree boot with headers instead of a straight boot as comes factory. Aurora can supply a ready-to-install set that way based on the standard OE set.

Let us know how they hold up after a few yrs. My 99 2500, 6.0 has the orig wires in it at 214,000 miles. Probably time to change them. I'll likely change them when I change the head gaskets that seem to be the cause of a coolant loss issue. My El Camino was the last car I had with headers. No more for me. Too many heat issues on adjacent components.

My Magnecor KV85's (PN 85283) came in yesterday and with a cup of joe in hand installed them this morning. These are a great direct OEM fitting replacment for the LS-2 style'd engines. The box said for 6.0 Pontiac GTO but they were a perfect fit.

 

With that said I am sure glad I swapped the OE wires before I leave for 7 months. The rear driver and passenger side wires were soldered to the spark plug cap. They must have come loose over time and the constant arc'ing welded the wires and plug caps together. The wire tore off the boot on the drivers side and the cap stripped off the threads on the passenger side and I had to go buy two more E-3 plugs for those cylinders (hard top find in my town).

 

I finished up the instalation with a good coating of dielectric grease so hopefully that keeps these ones from doing the same thing. Magnecor has a lifetime warranty so I should be good!

 

My wife did make a very good observation after I was done. She said I told you not to drive in the ocean so much" :D "! Its bad for the truck. I just looked at her with nothing to say. I think she was right. The Pismo Beach salt probably was not good for those rear cylinders that rarely get washed during the rinse down's.

 

Overall these were a great choice and a better product than the OEM (lifetime warranty) at just a bit lower price (87.12). I will keep an eye on them for heat issues but so far so good after a 80 mile trip hooked to the Toy Hauler. They can withstand 600 constant and 1000 burst heat temps.

      6.2L L87 Powertrain Engine Noise (Lifter Failure) Question

      By newdude · Posted

      Engine failure requires radiator replacement per GM if it contains an engine oil cooler.  They do NOT want them flushed.  Radiator replacement is also required for the 6.2 recall if the engine fails.   Here is the TSB the dealer is referring to - 22-NA-074 1..2    Its a slightly older version, but the current version of it covers all model years 2000-2026.  So if enough failure debris was present, it gets an oil cooler.  If that is part of the radiator, it gets a radiator.  Also, same for oil cooler lines.  Those get replaced.     Now something like a 2.7 Turbo which uses an oil to water heat exchanger for the oil cooler, the radiator would be left alone but the oil cooler would be replaced, as well as any lines.

      Doing the right thing, replacing both valves is the way to go. The valves with the ball leak far more often than the schrader. Never cared for them. The accumulator really should be replaced if the system has had no pressure in it and it was a keeper, but since you're looking to sell it, bet you can get by. Did you pull the orifice screen and see what was there?   Shame you can't get 134a. Hopefully the previous repairs included dye.   Some of the R4s I messed with developed leaks where the line sets connected or the front seal. Had one where the HPCO was leaking. Front seal would only leak under pressure. See any obvious oily spots?   I've got nitrogen I use to test pressure and to help dry the system prior to evacuation.   Keep up the good work

      Next time you're on a road trip to a state where you can still buy it stock up on 12oz cans, you might look into getting certified so you can buy it where you are as well. When they switched from R12 to R134a the test for certification was easy, they basically just wanted the $25

      Getting greedy...   The AC pump has been replaced at least once per service records, and it's been recharged twice since 2018 or so, in approximately 2 year intervals between those charges.   It was done at the same shop...clearly they were enjoying the revenue of recharging the system periodically versus actually tracking down and fixing the leak. I learned that the owner was 88 years old when she passed in 2023, so maybe they assumed only a temporary fix was needed anyway.   The system is basically empty now, the compressor spins freely, so I'm guessing it "just needs a recharge".   I vacuumed it down, and it has basically held overnight. Doesn't appear to leak under vacuum, check! So it must leak under pressure. I don't have a way to pressurize the system and pressurizing it with shop air wouldn't be great for the air dryer (which is probably toast anyway?)   The dryer (accumulator? I'm not an AC expert) has a Schrader valve, but the high side has an old ball-type valve, which are notorious for leaking. It's clearly had schmutz blown out of it at one point because the line/area next to the valve is coated old black crud, which I assume is AC refrigerant residue/oil, or maybe even dirty dye. I think I'll roll the dice and replace the valves. I have a black light around here somewhere so I'll find it and shine it around the engine bay in the dark to see if there's any dye.   I can't think of another way to track down the leak other than injecting some dye (if it doesn't have any) and having it charged up. We can't buy R134a off the shelf here anymore, so I'll run it up to Jiffy Lube and have them do it. I think I have a coupon. At the very least, the charge should last long enough for a year or two, according to history. I think this truck will be long gone by then. But cold AC is a selling point.

      Got the truck back today.  Called them yesterday to get an update, and miraculously my truck is finished?!?! The $13k out the door was complete bullshit!  Ended up being over $14k.  They added some bullshit service bulletin that I cant even find, where they replaced my radiator without telling me or asking me, and charging me for it.  Need to do more research into it, cause they leaked the first delivered radiator was ran over by FedEX.  Sounds like bullshit to me. 2.5 Months for an engine swap, which ended up being remanufactured, not new; ****ing ridiculous.  Brakes are squishy as hell, not sure if its from sitting.  Will give a couple days to see it that figures it self out.  GAVE IT BACK TO ME WITH 1 GALLON OF GAS!  Just filled the tank the day before drop off, more bullshit.  My dash cam SD card was formatted, not really much I can do about that. 3 year, 100k GM warranty at least.  Time to sell it and say **** off to GM.  Bad experience.  Cant wait for the survey email to come through.  Overpriced Raptor R, here I come!
