This routes turbo coolant lines through the hottest region of the engine. Between 40,000 and 90,000 miles, the rubber sections and seals on those lines degrade from constant heat cycling — not catastrophically, but slowly enough that pressurized coolant begins to seep.\u003c\/p\u003e\n      \u003cp\u003eOn the \u003cstrong\u003eB58 inline-six\u003c\/strong\u003e, a plastic coolant connector at the rear of the engine develops micro-fractures that are nearly invisible without a pressure test.
