Will vapour blasting wreck my silent blocks?

[mickey c]

I have the dirtiest engine ever filled with brown sludge & runny liquid which might have been water. I like a clean base to rebuild it but am not fancying my chances of getting the silent blocks out & back in, they look ok & apparently new ones are not available.
I'd like to get the engine vapour blasted & the firms blurb states it's a 'gentle' process so can see that steam / water vapour should not cause damage to the empty engine but does anyone know what could happen to my silent blocks please?
Thanks
Mike

No, they will be fine from the vapour blasting but I'm sure they have to clean the heavy shite off first so depends what they use to do this but it would need to be something really harsh to damage silent mounts. Just my opinion though

Should be ok but why not cover them up prior to blasting.......Duck Tape usually works ok and obviously don't blast too much in their direction.

Thanks chaps
That was what I was hoping & saves me a tricky job.
Covering is also a great idea, I'll get some big washers to bolt over them.
Thanks again
Mike
