Exhaust leak at manifold

[1BAD91]

Hey guys i have a 91 mtx thats been sitting for about six years me and my dad still start it every 4 months or so and it still runs great for having 200+ miles on it.it has an exhaust leak on the rear manifold.my question is can we fix it without removing the head?i want to start driving it again and that and new timing belt needs to be fixed first. Thanks

Where is it leaking at? It might be that the y-pipe is not seated properly. You do not have to pull the head to replace any exhaust gasket, or fix any exhaust leak from the manifold.

Ive asked this same question before on here a long time ago and someone said almost the samething he said that an exhaust manifold leak doesnt happen very often.i do have the aftermarket y-pipe with the hollow cats ive checked around it before but it seems like it was fine. But its been a while since me and my dad has worked on it.

When the exhaust has a leak, it will have black build up on the pipe from where the exhaust is escaping. You can look for that to diagnose where the leak is coming from. Also, make sure your oxygen sensors are tightened up and not loose.
