  1. 2011 Chevy 1500 LT crew - 144k miles So, after countless hours of searching, I’ve decided to post here in desperate need of help. My truck is currently in the shop, and on its 3rd mechanic trying to diagnose/fix the issue. Originally I was getting an oil pressure sensor unit code months ago, and about a month of driving later, and I finally lost my oil pressure gauge (dropped to zero) but the truck was perfectly fine. No loss of oil, etc. So I brought it in to get it fixed and change the oil - they put an OEM part in and changed the screen. Reset everything and I picked it up, a few moments later my check engine light returned. Scanned it when I got home, same error code - active. Checked for oil leaks, etc - nothing. Returned a month later for them to fix it, they put in another OEM part and new screen…drive it 3 miles down the road, and it trips again. They’ve checked the valve cover gasket and checked the PCM, everything seems fine. The truck is not burning oil either. I’ll add that my oil pressure gauge on my dash works fine now since they swapped sensors too. Everyone is stumped on what to do, and I’m about to potentially go down the rabbit hole of ‘throwing parts at it’. Starting with the PCM and then the valve cover gasket, and many thousands of bucks potentially. Does anyone have the slightest idea what’s going on? The PCM is throwing no other codes either, he has graphed and checked it. Is it possible for the PCM to be corrupt without it giving errors, etc? The tech is a 30 year vet, and a family friend - so by no means is he stupid. But this has stumped two other techs with equal experience too. Now my truck is past inspection, and with my Check Engine light on, it’ll never pass. Plus I’m still half way on my loan, so just selling it isn’t an option. Help!!!!
  2. Just bought this vehicle yesterday and now on the way home going interstate speed’s it’s making a noise like a window was rolled down or something and making my ears hurt along with my wife’s is this normal or is this a common problem and if so what’s the fix?
  3. Hello, Wondering if it normal for my oil pressure to shoot up with the RPM? I have a 4.3L v6 in my Express. Proper oil was used? What could cause that? Will this become a problem for leaks later? That's what I'm afraid of. Thanks,
  4. I was at the dealer the other day getting a tire replaced and I noticed I needed a coolant flush as its been 5 years and no previous one. When I got home I checked the reservoir and it was grossly overfilled. I doubt there's room for 7oz of expansion in it. I know sometimes this happens because it needs to burp out some air so I've driven it a couple of times but it hasn't gone down yet. I've got one of these coming tomorrow to suck the excess out if it hasn't gone down tomorrow but wondering if anyone knows about burping these or how to remove air. There doesn't appear to be a radiator cap which is likely why the reserve tank is pressurized. https://www.amazon.com/gp/product/B07CP8R9MS Since these are pressurized reservoirs, it seems that a grossly overfilled can cause damage as there's nowhere for the pressure to go except the weakest link which is likely a hose or fitting. My question is do these heater cores have a valve or is coolant running to them constantly? It is dead summer and I want to avoid heat on full to see if it clears out if I can. Also judging by design, it seems like it would naturally burp itself fairly quickly. Before the flush my needle almost always stayed constant at 210 when warmed up, now it seems to fluctuate between the 197.5 mark and 210 which leads me to think either there's still air in there or the overfill is causing excessive pressure that is altering the temp.
  5. I have a 2006 GMC Sierra 1500 4x4. A/c has been out for over 2 years had a bad compressor never got around to fixing it. Today I replaced the compressor, condenser, accumulator, orifice tube, and flushed all lines. Took it up to my buddy at the dealership and we charged it up. Put it under vacuum for a bit and no leaks. Drove home about 12 miles no problems blew ice cold. Left to go to the store about 2 hours later started it up the ac button was on but clutch wasn’t engaged and ac blowing warm. Turned the button off then back on clutch engaged and blew ice cold. About 10-15 seconds clutch disengages blows hot cycle the button again blows cold again. Every 10 seconds or so it blows hot and I have to cycle the ac button on the dash again get cold air. I know the compressor clutch should cycle on and off that’s normal but I don’t think it should be that frequent and you shouldn’t feel that significant of a temperature change right? And when it cycles off it doesn’t come back on unless you cycle the button. I’m thinking a issue with the low pressure switch on the accumulator but any advice?
  6. my 6.0 with 230xxx has low oil pressure but no knocks maybe a little tick though. When i bought the truck it had maybe 5-9psi cold dropping to 0 warm. Thought it may have been a pickup tube oring or oil pump so i went ahead and replaced the pickup tube, o ring, and pump. it now gets 20 cold 7 warm at idle and 0 warm at idle and 20 warm running 1700 rpm. Which is a lot better but still a problem. I am aware the bearings may be shot and need a total rebuild, that is not out of the options. It is not electrical or sensor based issue same psi with a mechanical gauge. However I need to replace my harmonic balancer and take off the timing cover again so i was looking at it and could it be as simple as a o camshaft retainer plate? it has a build in thin o ring which if fails will drain pressure as it connects the oil gallys. Am I correct in thinking that this could solve my issues? Any input is helpful, thanks.
  7. So I've been looking for solid information on how much pressure to put in tires, when moving away from stock tire size or type ("P" vs LT, different load range, etc). I never found anything to-the-point, except I remember someone talking about using GVWR and max tire load to calculate pressure. And I can't even find that post anymore. Anyhow, I decided to make this from scratch: https://docs.google.com/spreadsheets/d/17gh6VmylZWld50XcLvPbQVRRQoRFUZNiqndHQ7jzTb8/edit?usp=sharing It doesn't mean that it's exactly the tire pressure you should use, but I guess it's a good start. I hope it might be useful. Cheers!

  9. Hi guys, new here! I have done a lot of research trying find a TPMS reset tool that will actually work with the thicker mud tires. I bought one from Amazon, the JDiag model, which works fine on a friends 15' Silverado, but I can't get it to work on my 14' Sierra. The only thing I think is keeping it from working is the fact I have the BFG AT KO2's which are a much beefier tire. Has anyone had any luck resetting their sensors with this type of tire, or any other heavy duty tires like on the 2500/3500's? If you did, which reset tool did you use. I see a lot of people saying they can't reset their sensors, but now I wonder if the thicker tires is what's keeping us from doing so?
