[s-cars] S6 pinging woes - the continuation

[joe.pizzimenti at gmail.com]

Very informative, thanks, but what you do on the weekends is your business.  

Fact of the matter is, if a compression test comes out okay, there is really no need to waste your time doing a leakdown test.

Feel free to hit yourself in the head with a hammer, though.

It takes just a few seconds to whack yourself in the head with a  
hammer. That doesn't make it worth doing. I totally agree with PJM, he  
hit the nail on the head.
