Piston Slap: A Panther Love (EVAP) Purge?

Dear Sajeev,

After reading TTAC for many, many years I succumbed and finally got me some panther love. It blows my mind that Ford can make such a well-balanced, corner-carving sedan and then never sell it to civilians. I traded my 2006 Mazda 3 for a 2006 Police Interceptor Crown Vic (170,000 miles). The aftermarket exhaust makes it growl and it parts the sea of entitled BMW drivers hogging the fast lane like a dream. Unfortunately, due to living in glorious urban hellscape that is Oakland, I have to pass smog regularly.

Piston Slap: Solving the Black Box Mystery

Hey Sajeev,

I have an auto parts question that I’ve been meaning to ask for a while but I keep forgetting about it. Back in February, going to my car after doing some shopping, I spotted a cute college woman acting strangely around her Volvo 850 sedan. She’d walk around it a couple feet then would look underneath it. I angled myself to take a peek and I saw her problem; there was a large black box being dragged next to the left front wheel. After exchanging pleasantries and a failed attempt to get the hood open (the car was an obvious salvage, the whole front end was visibly skewed to the right), I finally just reached under the car and popped the box out, muddy and snowy parking lot be damned. At the time I thought it was a windshield washer reservoir, as the hose that was holding it on was a similar size and had a similar fitting to a windshield washer line, but when I got home I realized it couldn’t be. There was no way of filling it or checking its level.

So what was it? My memory has faded on it a bit but it was made of jet black plastic, was roughly the size of a 124 count tissue box, had a hose at the top and two fittings at the base, there was a sponge inside of it and the whole thing came down from in front of the driver’s side axle line. It had some major road rash so all of the parts might not have been there. The thing that I really remember, though, that it was branded with the GM “Mark of Excellence”!

  • Zerofoo The green arguments for EVs here are interesting...lithium, cobalt and nickel mines are some of the most polluting things on this planet - even more so when they are operated in 3rd world countries.
  • JMII Let me know when this a real vehicle, with 3 pedals... and comes in yellow like my '89 Prelude Si. Given Honda's track record over the last two decades I am not getting my hopes up.
  • JMII I did them on my C7 because somehow GM managed to build LED markers that fail after only 6 years. These are brighter then OEM despite the smoke tint look.I got them here: https://www.corvettepartsandaccessories.com/products/c7-corvette-oracle-concept-sidemarker-set?variant=1401801736202

  • 28-Cars-Later "The VF 8 has struggled to break ground in the increasingly crowded EV market, as spotty reviews have highlighted deficiencies with its tech, ride quality, and driver assistance features. That said, the price isn’t terrible by current EV standards, starting at $47,200 with leases at $429 monthly." In a not so surprising turn of events, VinFast US has already gone bankrupt.
