Replacing rubber mounts & fixing oil reservoir on Husky 141

Edit:

I took this saw apart to find where the chain oil was leaking from. Looks like a seam leak from where the two plastic halves go together. I tried sealing it up with some black RTV, but its still leaking. Is this the type of issue that is fixable, or should I be looking for a new chassis?

Also, can anyone describe a good way to replace the rubber and metal chassis mounts? Do they just get dug out with a screwdriver, or are they supposed to slip out? I broke a couple and the remaining rubber part seems to be stuck in there.
