I'm fairly certain I have a cracked manifold on my 2004 4.0. If so, would wrapping a new manifold with exhaust wrap help to prevent further issues? I figure it would help the manifold stay cooler.
Ok in theory yeah wet = rot, BUT with as hot as the manifold gets it drys very quickly.... I wrapped my exhaust to keep heat away from tranny and TC and even in wet weather you can hear and see the steam coming off it...it's drying.Wrap is not for sealing or repair of cracks. Furthermore most exhaust manufactuers do not recommend wrap on a street car. The wrap when it get wet will hold moisture and contribute to the exhaust rotting out much quicker.
