engine drop & motor mount questions - 1977 911S

![Question](https://rennlist.com/forums/images/icons/icon5.gif)
Hello all,
My mechanic will soon be dropping my engine to address the leaking rear main seal. He'll also adjust the valves and handle other leaks (oil return tube/s).
Here's my question: How many new motor mounts will I need? Two for engine and two for transmission? Though my mechanic said I might not need new ones, I really assume I WOULD need them on a high-miles car with engine of unknown background.
Any reason why I shouldn't go with the "sport mounts"? (These are not the solid ones.)
Thanks for any input and opinions,
-Shelley

I replaced the ones on my 84 with the OEM Sport mounts as well. MMs (not the solid ones for "racing" are rubber based and wear/dry out. Replacing mine cut down on a lot of motor vibration.
I vote, do it with the sports.

Shelley,
I replaced the engine mounts on my 81SC with the 'sports' version, and certainly felt better about having them, but to be honest, I don't remember actually noticing a difference. Maybe what I replaced was already too hard

Bill, Randy, Kurt V --
Thank you for the real world reports -- and I now understand I will indeed need 4 motor mounts. Also, I hadn't realized that my compressed OEM mounts may in fact be in "sport mode" already!
Take care all,
