how do you tell if an engine mount is good or not i replaced mine probably within the last 2 years and dont have 10k miles on them no leaks. i had a guy say the passenger one was collapsed but the drivers and passenger are same height and look fine. i think he was trying to just get money but ive wondered since. i worked on the car today on a lift and did tons of inspection. they looks fine to me?

although probably more than 50% of this cars use has been racing which would cut life expectancy down.

 

All I know is my 300e had a bad one one PS,it leaked rusty oil for 2 weeks on the ground,after 20 years they go kinda flat? also the engine will have strange vibrations! mine seems fine at 35k,pass!
