Alright guys, so pretty simple question today. What do y'all think of these E3 spark plugs? Are they worth the money? Or just a waste?

 

And what do you recommend as far as spark plugs go for these silverados?

never used em myself but I find it hard to believe the hype.

 

AC Delco, Champpion (the cheap 2$ plugs), NGK Iridium's are what I use.. the only advantage from the 2$ champions and the 20$ Iridium plugs is length of service, the AC Delco's are caught somewhere in between.

 

do NOT use Bosch, Ive done this and it was a mistake. truck never ran right the whole time they were in (which was about 2 weeks).. I may have simply had a defective plug, but it was enough for me not to go back.

i broke 2 bosch plugs in my last car, one broke while cruising down the hiway and luckily caused no damage, the other broke and took a chunk out of a valve with it. the first one the piece broke inside and the part that sparks to the tip was floating around. cant remember the technical term i just woke up. after that i stuck with ac delcos and never had a problem

If you do a search on here for E3 there are a few posts about them. From what I have read most have had a bad experience with them. I never used them. It seems from the general consensus is that most stick with AC or NGK and have great results.

 

I know Horsepower TV did a dyno run with them and stock plugs and showed a gain. But the dyno and real world is a little different IMO.

 

I guess you can try them and see how they do then report back. I don't need plugs for a long time so it will be a while for me to look into that area.

      Thank You Another JR, I watched the transmission temp the highest was 214, the engine temp seemed normal.  Hoping not a valve body issue, but...

      HighMileage oils or stay with Dexos 1 ?

      By Z45 · Posted

      dexos began as an effort for GM to control the oil change market because the Quick Lube Industry was eating into dealer service department profits big time. So they attempted to get other oem’s to develop standards as well and that would make it hard for Quick Lubes to compete because all the oems would be different. GM faced lot of industry push-back, mostly the quick-lube industry and they went to licenses. Still GM it making a ton of money (est'd 30-40 million in 2025) off the license structure as they charge a hefty fee to get oil tested then require a royalty on ALL gallons sold applicable to GM vehicles.

      Those are parts changers. It can get expensive though. I was a mechanic for 30 yrs. My truck has made this noise since new. I really don`t know what it is. It really doesn`t bother me. I`m still in warranty but have not brought it to the dealer.   I`m not buying the oil pump prime thing. Screw the TSB. I believe it`s in the trans pump gears. They rattle when that piss poor ULV oil drains off after a while. I believe those sharp tooth gears, with backlash, can rattle when dry. Not a vane style oil pump. Wonder who`s right? Me, or the TSB?🤔   Maybe I`m wrong?

      Wow I'm in a pickle. (Broke down truck) and a story.

      On the PCM side, blue PCM connector, pin 18, solid gray color (no stripe) wire circuit 435.  That is the EGR low circuit which an issue on that line (be it the wiring, the PCM or the EGR valve or system performance) will trigger P0401 when it tests that code.     There is also a VERY old TSB that states to make sure you clear the DTCs ANY time the PCM is unplugged, reprogrammed, or if the EGR valve is unplugged or replaced as the PCM has an auto zero function in the PCM for the EGR pintle data   61-65-59: SMU - SECTION 6E - ENGINE CONTROLS - CLEAR DTC'S - (Nov 25, 1996)   "CLEAR ANY DTCS FROM THE VCM ANYTIME AFTER DOING VCM REPLACEMENT/ PROGRAMMING, TURNING THE IGNITION ON WHILE THE EGR VALVE IS DISCONNECTED, OR REPLACING THE EGR VALVE."   Some diagnostic aid notes in the GM diag on P0401 for a 1995 S10 Blazer:   Diagnostic Aids Notice: In order to prevent further damage if the EGR valve shows signs of excessive heat, check the exhaust system for blockage (possibly a plugged converter) using the procedure found on the restricted exhaust system check. If the exhaust system is restricted, repair the cause; one of which might be an injector which is open due to one of the following reasons: Stuck Grounded driver circuit Check the oil for possible fuel contamination if a stuck open fuel injector is found. Poor connection or damaged harness - Inspect VCM harness connectors for the following conditions: Backed out terminal BL 18 Improper mating Broken locks Improperly formed or damaged terminal Poor terminal to wire connection Damaged harness Intermittent test - If connections and harness check OK, monitor a digital voltmeter connected between terminal BL 18 and ground while moving related connectors and wiring harness. If the failure is induced, the voltage reading will change.
