Engine mount

I’ve got big problems now one of the two engine mount bolts undid with great effort but the other one the head has rounded of I am in the process of grinding the head off hoping it Will then come off I have brought a replacement cradle complete the one that is held on with i think 4 bolts two at each end which bolts to the subframe does anyone know if this is hard to change thanks welcome to Mgtf ownership

It can be difficult, it depends how many seized fasteners you run into.

Which mount is it & do you have some photos ?

Have you tried it yet with a special tool for rounded-off bolts ?

The two bolts you mention are always very very tight, they weld themselves into the mounting, because of dissimilar metals there is a good chance that the bolt is well and truly fused in. I have an engine mount from a friends TF where both bolts had sheared and the engine dropped. both halves were unbolted from engine & subframe and replaced, two new bolts with copper grease on threads.
