I need to clean out the throttle, which is an absolute pain on the XJR6, so I was wondering if I could do in the same operation as swapping out the front crossmember?

Engine mount bushings are more than due as well, so I was thinking I'd support the engine with a hoist while the crossmember and do the bushings as that's being swapped out.

Since it's roughly near where I'd need to be to get the throttle body out, I was wondering if it'd be way easier to do with the crossmember out of the way? Thank you

 

The engine mounts between the left and right are different and there seems to be a problem in sourcing

There is a TSB on breather gas separator and a separate catch can mod components

 

The subframe being out of the way would certainly help. The throttle body on the supercharged cars is best approached from below, and can be removed with the subframe in place. Long arms help!
