I removed the old insulation on my Oscar and noticed some small bulges and dents in the boiler.  Is that a sign to replace the boiler or does it not affect anything?  I haven't noticed any foul odors when I brew/steam, etc.

Can you post a picture?

Bad pic, but this shows the dented / bulging area.

Bad pic is right.  I can't make out that area at all, but if that "bulge" on the bottom is actually copper boiler material turn off the machine NOW!  Unplug it NOW!

A boiler should never show a noticeable bulge, seam leak or any other deformities.  The boiler is under a good bit of steam pressure, and if that were to open up it could literally rip the boiler into shrapnel for your household.  We don't want that.

Take some better pictures if nobody else can diagnose from that photo.  I sure can't see it well enough to make a judgement.

You'll need to get all the insulation off, clean the outside and post a higher resolution picture, it's impossible to tell where the bulge is and what it looks like from that picture.

Eh, I think I'm just going to go with the "when it doubt, swap it out" theory.  

It looks like somebody struggled to removed some fittings and the pstat at some point, denting/bending the boiler a bit in the process.  I'd rather be safe than sorry.

Nuova Distribution lists the Oscar 110V boiler p/n 73003005 at $471.50USD FOB Washington. Maybe you should take it in and have it looked at by a professional because the cost of that boiler with shipping is going to exceed the residual value of your machine.

I believe that number is the entire boiler fitting setup.  Boiler plus wrap is about $120 from Elecktros.

Update:  boiler is fully disconnected and I scrubbed all the old insulation off.  Boiler is good and completely useable. Woot woot!
