Can I use a grinding stone on a nut on the starter? Will the sparks create a fire? Was gonna put tin foil around it, but it won't catch all of them
What is your question?
Stuck nut on starter. Starter is next to motor, 1 foot from oil pan and lots of grease/dirt around it (19 year old car). I've tried a breaker bar (not enough room), impact driver(not strong enough) and a nut splitter and nothing has gotten the nut off. Last option is a dremel with grinding stone and just cutting the nut, but it will make sparks. Can I lay down foil and be mostly ok? Or is the engine area of a car extremely flammable?

Is the nut corroded on, or was it cross threaded?
If corroded, use one of many available penetrating oils to loosen the corrosion.
If cross threaded, I would definitely avoid causing sparks if you are not a professional in a proper auto shop with proper clearance, access and safety materials. No one in this forum could ever suggest it would be the best idea to use a Dremel tool and generate sparks.
IF you’re having a problem accessing & removing the retaining nut using the correct tools - I doubt you’ll be able to get the Dremel tool in place to do any cutting anyway as it will certainly have more bulk that the required hand tools.
I can’t fathom not being able to remove the bottom retaining nut in the first place - unless maybe the proper ‘quality’ tools aren’t within your arsenal..
Good luck with it !
Search YouTube - you’ll likely get some pointers there.
