Piston Slap: 60 Percent of the Time, It Works Every Time?

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.

  • Jkross22 When I think about products that I buy that are of the highest quality or are of great value, I have no idea if they are made as a whole or in parts by unionized employees. As a customer, that's really all I care about. When I think about services I receive from unionized and non-unionized employees, it varies from C- to F levels of service. Will unionizing make the cars better or worse?
  • Namesakeone I think it's the age old conundrum: Every company (or industry) wants every other one to pay its workers well; well-paid workers make great customers. But nobody wants to pay their own workers well; that would eat into profits. So instead of what Henry Ford (the first) did over a century ago, we will have a lot of companies copying Nike in the 1980s: third-world employees (with a few highly-paid celebrity athlete endorsers) selling overpriced products to upper-middle-class Americans (with a few urban street youths willing to literally kill for that product), until there are no more upper-middle-class Americans left.
  • ToolGuy I was challenged by Tim's incisive opinion, but thankfully Jeff's multiple vanilla truisms have set me straight. Or something. 😉
  • ChristianWimmer The body kit modifications ruined it for me.
  • ToolGuy "I have my stance -- I won't prejudice the commentariat by sharing it."• Like Tim, I have my opinion and it is perfect and above reproach (as long as I keep it to myself). I would hate to share it with the world and risk having someone critique it. LOL.
