|They made that weakness worse once they
started using short gussets to move the breaking point with earlier
car at the bulkhead. They ended the gussets at the same hole! When used
for an exhaust pipe, the constant high heat through these holes
causes metal expansion and contraction at the weak point
which makes matters worse. A
Perfect Storm. As in other instances, they continued having that hole
even with Morgans that never needed or used
it after they stopped exiting through the chassis and exited, more
wisely, through the valences. To make holes in the valences is simple. even I can do it!!! But it is more tricky with these early Plus 8s.
Apparently, Morgan forgot to inform the chassis manufacturer of this move and the chassis kept arriving for years with this unnecessary hole. The only perfect solution is a chassis replacement. However, one can try welding a long reinforment piece +/- 2 feet along the bottom of the chassis at the weak point BEFORE a crack develops.
|Here is a
comment from the world's largest Morgan exhaust specialist and
installer with a decade's long impeccable reputation:
1. The orginal manifolds crack in the middle, They can be cast welded or stitched but it is a specialist job. 4. 5.
4.Javelin type column think it was ok for the LHDs but not 100% about that. (It can vary from car to car).
5.One has to replace chassis mounting brackets on both sides to the “L” shape type and at the end of the chassis for the doughnut rubber.
