The plastic mounting port was blown out of the aluminum coolant crossover of the plastic intake manifold

If it holds it is a good repair. If it hold long enough to get a replacement part it has done its job.

However, I would not do that repair on a customer vehicle. Just not something I trust on a vehicle I do not own, mainly because telling the customer to "watch this part here as it could come apart because I just glued it together" does not engender trust.
