First off there are many posts already detailing filling mounts in general and removing the stock torque mount off this vehicle so I have skipped that to simply focus on a filled mount. I filled the mount with the Loctite Roofing Polyurethane. From what I have read on the YouTube video, this is rated at about 40a. The key thing to remember though is that a majority of increase in stiffness in this case is coming from making the mount "solid". I am also looking to make a reduction in slop , with the least amount of increase in NVH.

Tape off one side around the holes of the mount and fill. Finished product will look something like pictures. I have a space heater on it now to help speed up the curing time a little before reinstall tomorrow morning. Temp on the mount facing the heater according to my temp gun is about is about 85, so I am not baking it. Will leave it on one side for couple hours before flipping to other side rotating like this until later this evening.

The other thing to remember is that this is being done on a hybrid so my increase in NVH, and performance, will probably be different than other models. That said it should hopefully eliminate some of the slop under heavier throttle applications when you can feel the engine moving. The hybrid uses the same mount as the 2.0t auto

Spectacular. Exactly how the car should come. Throttle response is greatly improved with almost no extra vibrations. Heavy throttle inputs are way smoother with much less lag before acceleration. Makes modulating the throttle easier coming out of a fast turn.
The added vibrations are extremely minimal, to the point they wouldn't be noticed unless you were comparing before and after. In the hybrid it's only really noticable when the engine comes on heavily like it does in the morning, or when it's warming back up. On the flip side the 1.5t mount had almost gotten rid of all the engine vibrations, to the point you could hardly tell when the engine was running. Unfortunately I was unable to weigh them because my one scale was too small and the other too big lol.
Based on this and how the mount attaches to the engine, if I were to do it again, I would I would actually go with a stiffer material than the Loctite, and something more like Polytek 60a that is pourable vs the adhesive(especially if you are starting with a softer1.5t mount). I still notice some damp looking tacky adhesive on the surface that keeps appearing after being wiped off, which I think is some of the adhesive curing off still. I also had an air bubble when filling the second time with the caulking gun. Polytek would probably eliminate these issues and be easier to work with. That said if your looking for the cheapest easiest way to do this, the Loctite is the way to go.
So if starting with a 1.5t mount, would at least go with a 60a material or stiffer. The 3M window seal dries to 80a would probably be the best for doing the 1.5t mount on the cheap.
