#0823: Lillian and the Thousand Dollar Valve

Original Air Date: 06.07.2008

   Best Moment

Is this Car Talk or "60 Minutes"? This week, 83-year old Lillian turns to Tom and Ray to help decipher a suspicious diagnosis from her usually trusty mechanic. Does he really want to charge her a thousand bucks to replace a valve? Has he succumbed to the beginning of boating season? You won't want to miss it, as our hosts go to the source to try to get the truth. Meanwhile, our Physics advisor Wolfgang is on-hand to administer a (well-deserved) dope slap to the boys for their (wacko) theory on head-on collisions. Also, what do you do when your Maxima's windows go cuckoo? If you're Adam in Baltimore, blame your girlfriend! All this, plus Tommy communes with nature and winds up paying for it in our new Puzzler, and lots more, this week on Car Talk.

Wrong on Audi A4

by WoomRR

I believe the A4 driver who heard wow-wow-wow with increasing frequency when turning left was hearing the tires. He told you that during the alignment the mechanic said his tires were worn. You suggested it might be power steering.

Favorite Moment: Lillian and Bobby. That call made be pay attention to the A4 caller.

Lillian Rocks

by Dione Murray

What a delightful, knowledgeable, incredibly spry gal! My day is better because I know Lillian is out there, looking out for her car and her grandchild. There wasn't even a hint of a whine. She was doing her homework.

Favorite Moment: My favorite moments were both when she said she knew her mechanic was honest, and that her tennis shoes were close at hand.

You Bozos Still Have it Wrong

by samuelrifman

You and your Harvard professor are completely wrong (again). Your point about momentum transfer completely ignores the fact that the oncoming car is DESIGNED to absorb energy in an impact! Thus it is FAR FAR SAFER to hit an oncoming car at your speed than a wall at twice the speed.

Favorite Moment: Waiting for a duhhh.

Wall vs. Car Issue

by metman

I think that Wolfgang oversimplified the crash issue. If change in momentum was the only factor, every stop sign would be a catastrophe. Time must be considered as factor for damage and injury. Relative speed at impact favors the wall option and energy absorbed by deformation will favor the oncoming car as the choice.

An Observation

by Ross

Great show, as always.

Favorite Moment: I'd just like to point out that when you were talking to Forrest from Sacramento, one of you asked him when winter ends. He responded, "End of February." One of you then asked, "And when pray tell does it start?" to which the other of you quipped, "About January!" Forrest, now answering seriously, said, "Around Christmas." I laughed when you guys seemed not to notice that this happens to be...right around January!


You know it's time for a new car when...

Yeah, these are unmistakeable.
