3.0 Exhaust Manifold Removal ?

[Rake722]

Quick check,

im pulling the manifold on the merc 3.0, removed 2 nuts on studs and 2 bolts under riser but the darn thing won’t budge - is there anything else holding it on or just the gasket making it stick ?

thanks

Need to find one more bolt

Its held at 5 points, 2 studs and 3 bolts (a serial number would help)

Thanks for the clarification, now to find the hidden bolt

Note the bolt pattern locations on the gasket and how they are positioned.

Did you remove the exhaust elbow riser? There is a 3/8-24 hex nut hiding behind it.
