More excitement.

Finished shimming the Olthoff motor mounts and fired it up in my garage. Engine came to life and immediately settled in at an audacious 4000 rpm. Pretty much cleaned out any cobwebs in my garage.

A quick peek under the hood revealed the throttle linkage had to be readjusted based on the engine sitting in a slightly different position.

Should I loosen and then retighten the tranny mount to allow it to adjust also?

Test drive - The Olthoff mounts increased NVH slightly. Not bad - maybe a slight tingling in the steering wheel. Car felt tighter & quieter. A lot of the low rpm “chain-lash” feeling was gone (however-could be due to the engine still idling slightly higher than normal-will fix tomorrow). Biggest difference was at mid rpm. The engine felt very smooth shifting at 4k. Ran up to 5k and it felt great. Good stuff…I’m happy and recommend the mounts.

Will see tomorrow morning if the oil leak is gone.
