Yeah, at this point it may be worth to get some cool aftermarket components, make it worth the trouble.

The statement is true but unfortunately your conclusion does not follow from it. The cooler doesn't replace the coolant in its job to cool the engine, it just helps. But like Rudy said, you need oil pressure, and any leak will make you lose it. The whole motor could be toast, just not making itself felt yet.
