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?

This Toyota is a prime example of Hyundai's primal influence upon the design industry. Just look at the years, 1976 > 1974, so the numbers bear Hyundai out and this Toyota is the copy.
