Well I think I found out I did! At that time it had a Borgeson box from Pete and a stock style Saginaw pump and no cooler and synthetic fluid, clearly that had its limits and I found them. It now still has the Borgeson box but now a Turn 1 aluminum HP pump, large aluminum reservoir and an external extruded aluminum cooler and its held together for almost 9 years of abuse. I think that fixed the problem....
