I do know the system was plumbed in series, however, my ignorance prevents me from knowing why re-plumbing them in parallel would change things. Does plumbing in parallel prevent the front cooler from being a restriction point since oil can flow past the front cooler while still filling it with hot oil for cabin heating??? Hmm, not sure how I would plumb this.
Without a temperature bypass or manual shutoff valve placed on the front cooler oil tubing, you may be re-visiting the current problem - cold thick oil getting hammered down 22 feet round trip of 1/2" aluminum tubing through a nose radiator.
Pressure follows the path of least resistance, so if the main mazda cooler's vernitherm is open, bypassing that cooler, it may be a non-issue.
I have no guarantee that vernitherming the nose cooler (at the firewall, at the fittings) will not cause the current problem, but I feel comfortable estimating that it is much less likely.
I'm not even sure theres a way to get a vernitherm off a mazda cooler without messing it up.
