Fraser Posted February 8, 2021 Share Posted February 8, 2021 Truck is 08 Granite, mp8, egr deleted. Has a slight drip at top of exhaust pipe. Fluid is yellowish and has no odor. Barely enough to wipe up but it’s there. Thought possibly egr cooler cracked , pulled it off and pressure tested, seemed fine. Truck runs great, no smoke. Any ideas ?
