Had an intake manifold leak to tackle today. Sounded like a choo choo train on a cold start when the engine idled down. Lot of caked on dirt and remnants of disintegrated wire loom under the manifold. Three of the ten vlom bolts were finger tight SMH.
Did an injection service yesterday in anticipation. At 150k miles, the upper part of the cylinder head ports still had some gunk on the walls, but you could see where the injector spray was hitting them. The valves were pretty clean as expected.
