I posted this in diesel discussion, but I want the best chance of getting some help so I'm posting here too.

I am in the throws of changing my oil cooler lines, motor mounts and engine shocks & mounts. The car is up on the jack stands, I'm ready to jack up the motor via the oil pan. I went to loosen the 8mm hex bolt under the left mount and saw it was already rounded out a bit. I sprayed it with PB blast and let it sit for a while after tapping on it. I tried to apply some heat for about 20 seconds and tried turning it which finished rounding out the hex bolt.

How should I go about removing this bolt now? It looks like tight quarters for whatever the solution is. The bolt head is accessed through a hole in the crossmember under the mount.

There are MANY postings on this in the diesel forum

Search on "stripped motor mount bolt"

Google it too.

The job is a PITA.

one way is to drive in a larger allen head or a torx head and then I would hit it with an impact wrench. Be sure to drive it in good and deep...all the way in before trying to turn it.

Good luck

Nail it hard with a torx - make sure it's jammed in there GOOD. Then it'll come out.
