This was from a 20 or 21(I wasn't the one working on it) DT Ram, 3.6. Came in for noise in engine. Yep bad lifter/cam noise in right bank. Look at oil.....oops, none on stick. No sticker on windshield, change oil warning on dash. Ask cust, when last change was, come to find out, it only had 2 oil changes in 50k, Klms. Oh Oh. Borescope down oil fill shows excess sludge. So we get permission to pull valve cover, with pretty much a guarantee its not going to be warranty. Found this mess. Every center intake lobe is wiped. Sorry sir thats a no go on warranty today. Probably going to be a 20k bill. We wont fix this engine, with this much sludge. Funny thing is, he bought a large extended warranty, that comes with free oil changes!
