For a few months now I have suspected a few worn out engine and gearbox mounts on the 2.5 - there was a little movement from the gear stick when putting your foot down and lifting off.etc Decided to replace the front snub mount, side engine hydro mounts (which had leaked thier fluid) and the final bush/mount was the rear gearbox support. I usually like a more "direct" feel and have fitted vibratechnics mounts to previous cars - as there is pretty much nothing aftermarket in the way of mounts, I decided to buy some poleurethane resin mix from ebay and fill the voids in a new rear gearbox mount. I chose a mix which was pretty solid (ended up setting like plastic) and fitted the mount last night. Bad descision - its effectivley solid, which transmits all engine vibration through the whole of the car! The resonation is that bad on idle you cannot hear yourself talk! (May grab a video) Will be removing tonight to try and remove some of the poleurethane from the bush without destroying it.
