Personally, I was thinking something stupid like buying a large heavy duty jaw clamp and clamping the motor mount or the area around it to hold the engine down, lmao.
What do you guys think would be good. Not looking for an expensive route, hopefully I don't have to.
Motor mounts work by supporting the weight of the engine and transaxle in a way that minimizes and isolates vibration and allows for movement caused by the twisting forces (torque) of the engine. Typically, a part of the mount is made by bonding a heavy piece of rubber between two pieces of steel. This rubber to steel joint is the part that usually fails, especially if the mount has been exposed to leaking oil. With some mounts, you can just replace the rubber (isolator) part when it goes bad.
When mounts go bad, misalignment of the engine and transmission with the drive axles and wheels can damage the transaxle and drive train components.
The only practical solution is to replace the bad mount with a new one. If you are really poor or cheap, you can get mounts really cheap at a junkyard. There is little call for them. Used mounts won't last as long as new ones.
You may have to lift the motor or transaxle with a jack to remove and install the replacement mount. Be careful where you put the jack and use wood blocks or plywood to spread the load when lifting on the oil pan of the engine or trans to avoid damage.
