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

Erik writes:

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.

Piston Slap: The Lambda V6 Half Life? (Part II)

Dennis writes:

You kindly responded last year to me in regards to an inquiry I made about my 2006 Sonata with the V6. I am still in love with my old beastie. She is approaching 93,000 miles and I just had new plugs and upper front control arms put into the ol’ gal.

I read some forums that go on and on about this model year’s engine having problems with the Timing Chain Tensioner. I took her to the dealer to have it checked….they did not hear any odd noises to warrant my concerns. However, in my extreme car paranoia, I swear on cold mornings I hear a rattle coming from the engine. My question?

Piston Slap: Running Interference for Timing Belts?

Clint writes:

I usually buy vehicles that need the timing belt replaced. (Most people trade in or sell at that point for $ reasons). I do most of the work myself because it’s not overly complicated if you follow a manual. People at my office ask me about general car maintenance. When I ask about timing belt changes they always respond with, “Do I need to change that?” or “I have never changed that.”

Hello Sajeev,

You’ve helped me greatly in the past, and I once again turn to you for your knowledge of used cars and reliability.

To refresh your memory, I drive a 2002 Chevy Cavalier Z24. It’s a 5-Speed Manual, with the 2.4L Quad 4 motor in it, not the lifeless 2.2. I’m about to hit 145k and I’ve got a few concerns about the car and what I should exactly do with it.

Piston Slap: A Saturn Wagon's Bad Timing (Update)

Dave writes:

Hello Sajeev,

Well, better late than never. I did get my Saturn running again. Due to weather, parts delays and misdiagnosis I spent a lot more time and money than I planned or had to, but she does seem to be in good shape now. Although the timing chain was still in place and looked OK, I replaced it. I actually did the whole timing set replacement, which includes chain, crank sprocket, two cam sprockets, fixed guide, top guide, adjustable guide and chain tensioner.

  • ToolGuy This thing here is interesting.For example, I can select "Historical" and "EV stock" and "Cars" and "USA" and see how many BEVs and PHEVs were on U.S. roads from 2010 to 2023."EV stock share" is also interesting. Or perhaps you prefer "EV sales share".If you are in the U.S., whatever you do, do not select "World" in the 'Region' dropdown. It might blow your small insular mind. 😉
  • ToolGuy This podcast was pretty interesting. I listened to it this morning, and now I am commenting. Listened to the podcast, now commenting on the podcast. See how this works? LOL.
  • VoGhost If you want this to succeed, enlarge the battery and make the vehicle in Spartanburg so you buyers get the $7,500 discount.
  • Jeff Look at the the 65 and 66 Pontiacs some of the most beautiful and well made Pontiacs. 66 Olds Toronado and 67 Cadillac Eldorado were beautiful as well. Mercury had some really nice looking cars during the 60s as well. The 69 thru 72 Grand Prix were nice along with the first generation of Monte Carlo 70 thru 72. Midsize GM cars were nice as well.The 69s were still good but the cheapening started in 68. Even the 70s GMs were good but fit and finish took a dive especially the interiors with more plastics and more shared interiors.
  • Proud2BUnion I typically recommend that no matter what make or model you purchase used, just assure that is HAS a prior salvage/rebuilt title. Best "Bang for your buck"!
