You can always tell which people held the flashlight for their dad. This channel is for all the people that try and do things for themselves, just like dads used to do.
I have a 2002 single cab dually LB7 ZF6 4×4 . I have 430,000 miles. I've replaced injectors, alternator, water pump and head gaskets with studs. I just spent $2,000 for a new dual disc clutch. 6 months ago almost 3,000 on a completely new kryptonite front end. Still much cheaper than a new truck.
Love your videos they’ve been super helpful for my lmm! I’m in the same boat with the p0087. I just bought my injectors yesterday because I’ve done everything else besides cp3. My question is what’s the update did you ever see the code again since doing injectors or did that seem to fix the low fuel rail pressure?
@braydenburbank5838 I have never seen the p0087 since. The unfortunate thing is, I cracked a piston about 3 weeks ago. I am so sad, I was gonna do a video once I get the truck back. I still love the truck, but I am really mad at it right now 🤑🤑🤑🤑
@@heldtheflashlightfordad6728 oh no! That hurt! I am looking out for the video though! I installed my new injectors over the weekend and it pulled great with no codes and feels like a whole new truck!
I have an 08 duramax and it idles at 28 lbs of pressure and as soon as I touch the throttle the oil pressure sensors light warning goes off. Changed the sensor and it still does it. Looking to see if anyone has any advice.
Exactly where my 07 LMM with 92,000 miles oil pressure sits as well, at idle and driving. Always worried me, but it definitely seems to be normal. I also had the low oil pressure light come on once after towing hard in the heat when it came down to an idle when i got off the highway. Probably going to toss a new pressure sending unit in mine just to see if it changes the reading at all.
Off subject! Oil pressure goes to nothing on gauge and goes up with rpm’s. Changed sensor. Cold oil pressure is good and gets worse with hotter oil. What do I need to change or do. I love the Duramax but I hate how close the gauge gets to the red. They need to change this
Going trough it now just got a 03 durimax 200 k miles lb7 just did releif valve and regulator and did great for a day then a little white smoke at idle and spudders then goes into limp mode
That's crazy... I've been fighting the obd code p0087 low fuel rail pressure low. I replaced the cp3 fuel injection pump also replaced the lift fuel pump inside fuel tank. Replaced pressure sensor switch along with fuel rail relief valve in front of fuel rail still having the p0087 coming up.
@@heldtheflashlightfordad6728 nope I thought about at the very beginning. And after testing them onto the scanner and individually diagnosed them. They check out to be good. After all there is no fuel on the oil fluid. Not sure
My old injectors tested good, too. My return rates were normal, I had perfect balance rates. Mine would only act up on the hottest days, pulling heavy loads. The fuel gets super hot and thin, and the injectors start returning too much fuel. It's almost impossible to check the injectors under these conditions. I've researched and found that the injectors need to be replaced or rebuilt in the LLY, LBZ, and LMM duramaxes at around every 160k-200k miles, depending on how hard the trucks worked, give or take. Doesn't matter if you changed fuel filters and added fuel treatment religiously.
@@heldtheflashlightfordad6728 see that's interesting. Due to cold temperatures she drives amazingly. It's when it gets to normal hot operation temperatures it's when she goes limp mode and can't drive past 35 let alone 45 miles an hour.
@francisco-javiergarcia4264 Hope you get it figured out. It's extremely frustrating not knowing when she's gonna just fall off. Mine always did it at the worst time, I've had to cut over three lanes of traffic with a damn skidsteer on the trailer. What a pain in the ass
Mines an 02 with 288k on it. I live in Fl and it gets hot. Mine was throwing the p0087 occasionally when it was hot and I had just run steady around 70-75mph and would stop at a light or such. On take off it would throw the code and limp. It started happening more and more frequently so I had to find it. Unfortunately for me it was the CP3 pump. A couple days and a lot of labor later ( and $$$) and it hasn’t done it since. Now, with this info I’ll know where to look should it do it again in the future. Appreciate it.
Do you have air bags in the back? I have a 13 gmc dually. Been back and for with keys to level up front. I haul over 20k lbs and and the back squats just a lil bit, I think if I put keys on the front will be higher with the load unless you have bags to level back out…. How is your set up? And is there any difference with towing with keys and without the keys ?
I have air lift bags in the back, and 2" keys cranked. Towing is still very comfortable, I run about 50-60psi in the bags when I'm towing heavy, and the truck sits perfectly level. I keep the bags empty when unloaded. Otherwise, the truck is way too bouncy
My 08 LMM is just like that. I was running Rotella and it was right at 30 psi. I changed to Mobile Delevac and gained around 5 psi. I have around 350,000 on mine.
My 2005 Silverado is the base model single cab with the cd and cassette player. I want to upgrade to an aftermarket system with Bluetooth and backup cameras. And then lose the ugly radio antenna. I subscribe to a simple radio app on my iPhone 13 that lets me listen to almost every station in America. But the truck’s radio has no auxiliary plug-in or Bluetooth. Will doing this wear out any phone’s battery too fast? Or is there a time limit for any phone’s personal hotspot usage?
That oil pressure is exactly what my lbz shows. I have driven or owned several GM duramax's and they were all identical to what your is showing. The angle that you view the gauge makes a huge difference. I was a passenger on a trip to TX with a buddy of mine that inherited a 2007 3500 dually dmax. This was in 2010. Truck had 27k on it and was in a barn in mint condition. When we fueled up before we headed back to FL, I leaned over and glanced at the gauges from the passenger side and it looked like it had about 10 psi oil pressure at idle. After fill-up, I drove the first leg back so when I hopped in the drivers seat the gauge read exactly as yours.
I have a 2005 extended cab dually that has the 6.6 ltr in it. I just pulled the oil pan off at 220000 miles.when i got everthing back together, theoil pressure started out at 30psi and dropped down to almost 0, and the motor still ran perfect. Im using t6 rotella 1540
I had same issue and I’ll tell you what. I did every replacement part from cheapest to most expensive. Every single upgrade was incrementally improved a little bit more than the last. But, if you do it all, you won’t believe how fantastic the engine runs when you’re done!!! 1-added helper pump 2-Cp3--way better fuel pressure!!!!! 3-injectors with factory Bosch’s But listen, ALL THREE HELPED BETTER AND BETTER! Don’t stop without a new CP3. Your fuel pressure improvement is ridiculously better! ZERO LAG.
