Am in the process of evaluating a purchase of a lovely 260 that has been well looked after. However on an inspection it has found to have a broken nearside, lower rear manifold stud that has sheared at the head.
There is slight exhaust blow when cold.
Upon investigation, it was found to be noted as broken by the servicing garage back in 2014 and apparently has not deteriorated.

We are being advised that this is an engine out job to rectify.

Would it be appropriate to leave problem as is or should it be repaired?

Would appreciate any thoughts on the subject!

Thanks, David
