This morning I pulled in to work and a friend stopped me to ask about his 2006 Ford Explorer. A week ago he performed an oil change on his 4.0-liter V6. When he was changing the filter, the old oil filter’s gasket stuck on, but he didn’t see it and double gasketed it. When he fired up the engine oil spewed everywhere. The oil level ran low before he discovered it and shut off the engine. He kitty-littered the driveway, re-installed the filter, and topped the oil back up. He started the engine and his lifters started ticking. As I stood there talking with him, I could hear multiple lifters ticking. Is there a safe and reliable way to get the lifters pumped back up without disassembling the top end?

I googled “Ford 4.0 lifters ticking” and apparently the engine family has issues with lifters ticking when they get old, but I can’t find anything pertaining to lifters ticking after running the oil level low. The recommendations I see are to run thicker oil, Marvel Mystery Oil, STP oil treatment, Lucas oil stabilizer, ATF, etc. Are any of these a reasonable solution for his problem?

I’ve also read to just drive the truck as normal and the ticking will go away. This is what I’m inclined to recommend. Do you have any better info?

Please let me insert a tip I learned as a technician: when you change your oil filter, always wipe off the filter sealing surface and you will never have this problem. (Read More…)
