Check if you are having a rough idle problem.

Just a guess, but are you sure you're getting the left motor mount on the left and the right on the right?

There should be a heat shield on top of the mount:

On the picture of your mount it is missing. Overheating may lead to premature failing.

as deanyel said there is a right and left mount from memory and that heat shield needs to be there.

for the left or right and epc star tek shows a little thing called (screening plate) it doesn't look like much of a heat shield

You did something wrong because EPC shows it as two different parts, left and right, with two different part numbers. A heat shield is a heat shield even if it doesn't look like much. You have two possible causes for the premature failure.
