As I have said in a couple other threads, I will be 72 in 9 days but still like to do as much of my own work as I can and I do work on neighborhood vehicles and for my American Legion and VFW.
Worked on a friend of an American Legion member's 2014 Silverado K2500HD with a Duramax. It was a simple oil change, so I thought. Has 143k miles on it.
Plenty of room to put my filter strap on and loosen it. It was on so tight, that as I am laying on my yoga mat style roll out pad, I pulled hard enough that I actually lifted the upper half of my body off the mat. I finally used my left hand on the filter wrench and my right hand grabbed the bottom of the R/F rotor and I pulled for all I was worth and it budged. I got a second grip and it budged again. 4 budges later I loosened it and drained and swapped with my preferred WIX filter, after lubing the new filter seal.
Then on to the easier drain plug, or so I thought. I had a long reach 13mm combination wrench on it and it would not budge either. Tried 2 more times with no luck. Thankfully the 6 point drain plug head was still looking good. I got a long reach Mac swivel head 3/8 ratchet with a USA Craftsman 3/8" drive short 6 point chrome socket. Pulled and felt it give. I was saying, "Finally" along with a few other choice words. Then I looked. The wall of the socket busted out. I had had enough at this point and called the owner and told her I was not responsible for however farther I went with this, She said, "Go for it". I got out my very powerful 3/8" drive Milwaukee Tool impact and Put a 13mm 3/8" drive impact socket, SK this time, and burped it a couple time and I put the wrench back on and it broke loose.
Done a few oil changes in my day but that was the tightest that I have ever seen where both were ridiculously tight. I expected stretched drain plug threads but they were ok and after draining, I installed a new Genuine GM drain plug, after checking seal surface of the pan and wiping clean. The rest of it went fine. I reset the oil life reminder and shipped it.
See pics. I told her it looks like a RMS is leaking.
