If so, check and make sure the draft tube is drafting. Easiest way would be to blow air into the draft tube exit pipe and see if it blows through into the engine.
If the draft tube is clogged up it won't relieve internal pressure and this pressure will find its way out, most times through seal and gasket locations.
Good luck
