If you had taken the manifold off your self you'd have a better idea of the scope and problem. Is there a 'hole in the block'? Doesn't look like it.Do broken studs need drilling and easy out? Should replace the remaining stud at the same time.Will chasing out the threads and new studs properly installed with new gasket cure the issue? Maybe a second or third confirmation would help .This is not rocket stuff. Or trust the guy to install new Isuzu and gear and learn the love the little bugger.
