Piston Slap: Do We Have ALL The DATA?

Hey Sajeev, remember that Mazda 6 that had the headliner problem? The dash storage problem? Got another one for ya.

From what I understand, the 2006 Mazda 6 V6 manual is fitted with 3 engine mounts: left, right and (dog bone) lower. The lower mount was replaced last year (on my birthday coincidentally) and less than a year later, I noticed it had gone bad again after feeling the engine rocking a bit in the bay. I carried my beloved back to my mechanic who replaced the lower mount (under parts warranty) and asked him to check all the mounts. According to him, all were ok. But just last week while I was doing my oil change, I noticed the lower mount (which is right behind the oil pan) was already going bad.

This baffled me and also caused the mechanic to again scratch their heads. One of them noticed, believe it or not, a FOURTH mount located directly above the lower unit. They took the car off the lift before I could look at it but a quick internet search doesn’t turn up anything regarding this mystery FOURTH mount. Any ideas?

Piston Slap: A New Wrench, A Good Wrench

Hi Sajeev, I have to find a new mechanic – my former mechanic is permanently disabled (bad shoulder – he can’t even hold a gallon jug of milk with his right arm) and his old shop is just not responsive – or as competent as I demand. So, with great heartburn, I have to find a new shop for those repairs I am either unable or unwilling to perform myself: which is most since I do not have a garage or even a driveway, much less a lift or even jack stands as the street in front of our house is pretty well sloped.

The cars in question are my resto-mod 3.0L Contour SVT, my wife’s Camry and probably my mother in law’s Millenia S (with the weird miller cycle engine). I can tackle basic repairs with my car, but sometimes it’s just easier to have someone else do it.

How should one go about finding a new mechanic / shop? What questions do you ask to determine competence? I proved a long time ago that I knew more than my local Ford dealers (including causing service advisers to get fired due to my complaining about their ignorance – including yelling at one standing underneath my car on a lift arguing about the rear sway bars), but I am not opposed to company shops if I know the mechanics are competent and the rates reasonable.
