The car is not blowing any heat despite heat being turned all the way up. I recently used blue devil oil stop fix which I've read could have clogged the heater core.

The temperature gauge on the dash stays at about the mid point the whole time Im operating it so I don't believe it's overheating. The coolant level also does not seem to be dropping nor does any coolant seem to be dripping into the cabin which I heard can be an indicator. The car windows do however fog up though which I've read could mean it's clogged.

I was wondering if the car is still ok to drive for now or do I risk doing more serious damage to it. Also would a heater core flush potentially take care of the problem.

Let me understand this. You used OIL sealer in the coolant system?

Cars windows fogging up means the core is leaking, not clogged.

In the meantime with the engine warmed up to full operating temp locate the 2 heater hoses that go into the firewall and feel them for temp. Are they both too hot to continue holding?

Why would you use oil stop leak in a cooling system???

Any type of stop leak is just putting a band-aid on a problem to try to buy time and some stop leaks can actually turn a small to medium problem into a huge expensive one.

I would start by getting that junk out of your system.

I'm not sure of your experience level but you could start off by feeling both heater hoses when the heater is on to see if they are both hot. If one is cool/cold then your core is plugged.

If your windows are fogging up on the inside, then as HT already said, your core may be leaking.
