short of doing what your going to manage this bill, would it be viable to pull the head and have a looksie and confirm it one way or the other ?
Here is the Teekay, you can buy them from Repco;

As for pulling the head, If you pull the head and find nothing, it's an expensive exercise. If you pull the head yourself and find an issue, I bet MMA will put you through the wringer for warranty. however, they can't deny the results of a Teekay test, as they probably (should be!) doing this themselves before deciding to pull the head.
I could be wrong here but I think the Teekay test isn't really going to tell you anything unless your block is already leaking... I bet there's heaps of faulty MN engines in service that would never show up in this test. The only time this test may confirm a problem is if you already suspect the issue, such small coolant loss, pressurised overflow bottle ect.
As for the higher rated cap pressure, 2.6psi combined with less thermal conductivity from the new coolant ratio... Hmmm Mitsubishi has implemented this to put extra stress on the block in the hope that it will weed out the weaker engines. Obviously this HAS put substantial stress on the rest of the cooling system ancillaries. Already we have seen members here with blown hoses and cracked radiators.
Despite what MMAL have said about the newer MN engines being "fixed" Sorry to burst everyone's bubble here but I believe that ALL the 2.5 MNs engines have the defective blocks. Just at varying levels of poor quality. Would explain why the new MNs still retain the higher pressure cap and 50% ratio coolant. Tick tick go all the MNs.
Just my opinion though.
I totally agree "..... All the 2.5 MNS engines have defective engine blocks". I was told it was I in 4 with the faulty engine blocks by the service manager, but they couldn't identify which ones they were BS. I now believe as you do that the all the 2.5 engine blocks are defective and that MMA knew this but sold them anyway on the premise we'll fix them if they go. With mine it only broke down under load towing a caravan. So some that are never used for towing etc may never have the problem maybe, or is it a ticking timebomb down the track. I would not trust one. I believe it is the biggest cover up by MMA, but I'm not letting it go stay tuned......
