Piston Slap: Hands-on Questions for the Touchless Car Wash?

Seth writes:

Sajeev,

I’ve admired your columns from afar for years, as a non-commenting TTAC reader. I especially appreciate your tenacious appreciation, possession and maintenance of cars you love. My automotive life is not nearly as exciting or robust.

While I love my cars, with two small children, a wife and a full-time job, I only have time and money for two at a time (his and hers). I aim to keep them for at least 10 years each. So, I obsess over the scratches and dents knowing I’ll be stuck with them for that long. Ridiculously, I even worry about scratches from washing them.

Which brings me to my question: What’s the best automatic car wash to use to minimize paint damage?

Autoworkers, Agribusiness, and Algae: Toledo Back in Business, For Now

Toledo, Ohio has just squeaked by a major environmental crisis. A toxic algae bloom in Lake Erie poisoned the city’s water supply, leaving over 400,000 residents high and dry for three days. Restaurants, schools and businesses closed, the National Guard trucked in water, and the governor declared a state of emergency. Meanwhile, Fiat-Chrysler had to resort to creative measures to keep its Toledo Jeep plant running.

Piston Slap: Bustin' Carbon Down Mexico Way!

Hello Sajeev,

I’m a long time reader, but not much of a poster. Anyway, I currently own a 2009 SEAT Leon (bought new, I’m from Mexico if you wonder how I got this car), which is basically a 5th gen VW Golf in drag, 1.8 TSI engine and 6 speed manual, 32k km in the odometer (about 20k miles) almost 100% of city stop and go traffic. Currently, there’s nothing wrong with the car, but today I took it to the dealership for the vehicle emissions tests (all good) and looking at all the services that they provide I found this: Engine Carbon Build Up Cleaning with Hydrogen, so I ask the service representative what it was, in he basically told me that a machine is connected to the fuel system of the car and they feed it with hydrogen and keep the car running for about half an hour, and that should remove all the carbon build ups in the system.

Reading this and other forums I learned about the propensity of major carbon build in the valves, regarding the direct injected engines, so I found this interesting. Googling this cleaning system, I rapidly found about it: OxyHydrogen Engine Carbon Cleaning, although I just barely read about using it in scooter engines.

Then it came to me!! Ask Master Sajeev about it!! So I’m wondering if you ever heard of this system and if it’s really effective in removing carbon build ups, or if it is a bad idea to ever think about it. Dealership charges about $50 to perform this service by the way….

Saludos desde México!!

  • Brendan Duddy soon we'll see lawyers advertising big payout$ after getting injured by a 'rogue' vehicle
  • Zerofoo @VoGhost - The earth is in a 12,000 year long warming cycle. Before that most of North America was covered by a glacier 2 miles thick in some places. Where did that glacier go? Industrial CO2 emissions didn't cause the melt. Climate change frauds have done a masterful job correlating .04% of our atmosphere with a 12,000 year warming trend and then blaming human industrial activity for something that long predates those human activities. Human caused climate change is a lie.
  • Probert They already have hybrids, but these won't ever be them as they are built on the modular E-GMP skateboard.
  • Justin You guys still looking for that sportbak? I just saw one on the Facebook marketplace in Arizona
  • 28-Cars-Later I cannot remember what happens now, but there are whiteblocks in this period which develop a "tick" like sound which indicates they are toast (maybe head gasket?). Ten or so years ago I looked at an '03 or '04 S60 (I forget why) and I brought my Volvo indy along to tell me if it was worth my time - it ticked and that's when I learned this. This XC90 is probably worth about $300 as it sits, not kidding, and it will cost you conservatively $2500 for an engine swap (all the ones I see on car-part.com have north of 130K miles starting at $1,100 and that's not including freight to a shop, shop labor, other internals to do such as timing belt while engine out etc).
