2011 Scion tC

Hi, Sajeev!

I read with deep concern your notice that the Piston Slap mailbag was empty. You kindly answered my previous query about putting more conservative tires on my ’11 automatic tC (now at 51,000 miles), despite the fact that I erroneously addressed the email to your parasitic e-twin Sanjeev, and I’m happy to pester you/be of service once more. Please find, below, my questions, and thank you for your time.

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? (Read More…)

Hi Sajeev and your goateed evil twin Sanjeev!

Beige. We all know it, we all love it, especially when it comes in Lexus Pearl White as my wife’s 2003 ES 300 does. This vehicle has had exactly one non-maintenance item replaced since bought new: the A/C compressor relay. My wife installed it since her office is near the Toyota dealer. And it was July. In Nashville. It was my research in the Lexus forums which led to this fix for the flashing LED in the A/C button.

Which brings me to my question. (Read More…)

Hi I would like to know what is the difference sound of a tappet noise, or bad rocker, or a piston slap. Thanks regards.

I always enjoy reading Piston Slap and want to ask about my truck, a 2007 Nissan Frontier with the VQ40DE (4.0L V6), 6-speed manual, and 42k miles. Sometimes the truck will rattle while accelerating at around 2200 RPMS. This only happens after completing a long freeway run (an hour or more) and occurs in every gear regardless of throttle position. The noise goes away after a few shifts or always after the truck has been shut off and restarted. It has been going on for 6 months or more (it took me that long to figure out how to duplicate it) and doesn’t seem to be getting any worse, plus it doesn’t trip any check engine lights. I can’t imagine how to replicate the noise for the dealership service department. Any ideas? Computer issue with the air/fuel mix maybe?
