Your post of 2 Mar 2011 was a great explanation regarding the cause of the “T” joint oil leak I’ve been experiencing. No one on any of the normal Ford sites has been able to pinpoint the problem, so I thank you for the information. (I’d discovered the source, but didn’t know the cause/fix until your post.) TTAC is now on my Favorites list! (Read More…)
I’m trying to wring a few more years out of my 1994 Geo Prizm, and recently the engine got louder. It’s a very low end bass like sound that makes the whole car vibrate a lot more.
The muffler and resonator are relatively new, and the noise seems localized to the front of the car. What’s odd is that the engine is the loudest when it’s idle. As soon as the RPMs go above 1500, the engine is only a little louder than it normally would be. How do I find out if the problem is the exhaust manifold, or the downpipe from the manifold to the catalytic converter? Over the summer there was a brief time when coolant was leaking and dripping down onto that downpipe and burning off. That leak issue was addressed, but that downpipe has some rusty sections on it anyway.

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?
