Engine mount gap

All,
I am helping my mechanic install my overhauled engine. We are installing the vibration isolators. There is a gap between the engine mount welded on washer and the vibration isolators. Is this a normal thing on maules or do I have something wrong? BTW it is a1981 M6-235.

A picture would certainly help, but I don't think there should be any space between the rubber mounts at all.

Not good. Needs to be flush with the isolator. Looks like it's been in a wreck.

They definitely look bent either by previous damage or during the welding process. I went back and looked at my pictures during my overhaul process and my mount flanges are all flat with no space.

Closest pics I have before the mount was redone.

Where they high pressure sand blasted?

The "before" photos are the way they are supposed to look. Definitely looks like the result of a welding process that wasn't corrected. At this point the outer edges can be pulled forward, and then surface plane the whole mount surface.

Ray just to clarify the second set of pictures are my mount not the original posterâ€™s mount.

I apologize for the mix-up Greg. Thanks to you for posting your photos so that we can all see how the flanges are supposed to look.

All,
Thanks for the help. After talking with my mechanic some more we decided to fix it like Riverbuggy mentioned. It was involved in an incident. It was a low speed, low power, taxi incident. It should not have caused this damage. Everything in the engine was checked and was fine. Freedom, I did blast it in a cabinet with glass bead.
