Today, I met up with
@CowTownRacer and we spent a few hours changing out my engine mounts with the BFI stage 1 set. While in there, I wanted to refresh the seals on my upper timing cover as it's been sweating for a while. We ended up having to run down to the dealer to buy a new cover as the old one's gasket groove was broken...

Since I had to get it at the dealer, and the new gasket would not seal at all (it would just start to tuck into the cover at the breach), I got shafted at the dealership -- $230 after a 10% discount.
As for the mounts, I was replacing them as an investigation since I've had a very strange body vibration on decel between 2,500-3,000 RPM that was completely unrelated to transmission, wheels/tires, suspension, axles -- it was coming from the engine.
While taking the old mounts out, we noticed that the bolt keeping tension on the poly/metal/poly sandwich (engine side) was completely loose, it had released all clamping force and was backed off by at least a thread or two. I'm surprised I was only feeling a specific, occasional shake.
We buttoned everything back together and got in for a spin around the block -- we both immediately noticed how much smoother the engine felt. No teeth-chattering, less NVH than before. On my drive back home, I noticed that not only has engine operation smoothed out, everything also feels tighter -- my throttle inputs feel more direct now. I can hardly tell the engine is on while at a light now. I'm incredibly impressed with these mounts and I'm pretty pleased I went with this set!
