Frozen bolt on intake manifold

Hey everyone, picked up my first wrangler ('95 2.5L, 160k miles) first time posting on forum just signed up today. Im taking out the intake and exhaust manifold to replace the freeze plugs. Got the initial bolts loose except for one right next to the intake manifold and theres not alot of room for leverage due to the manifold. Ive been letting it soak in some oil penetrator and tapping it but its still frozen. Any ideas? Thanks

try wrapping a string around it soaked in PB Blaster. otherwise, is it in an area where you can apply some heat?

Get a can of MAP gas. Unless you can get a hold of a small acetylene torch. Just stay away from anything thats flammable. And wear gloves.

Yeah, if you have the time give it a couple good days of PBlaster to soak in. Otherwise try the blue wrench to heat it up.
