I've got a 2007, 6.0, ARP studs, EGR delete. Last weekend i installed the sinister diesel coolant filter kit and billet oil filter cap. Yesterday i drove it from from South Carolina to Maryland towing about 6,000 lbs and about and hour away from my destination it started the "tea kettle" whistle. My standalone gauges weren't showing abnormalities, EOT was 200-220 and ECT was 190-210. I wasn't losing coolant anywhere that I saw. I made it to Maryland last night. This morning I move my truck to the driveway and shut it off. 10 minutes later I notice a puddle of coolant under the driver side door and I can't see exactly where it's leaking from. I started it up to see if it got worse. The only thing I noticed is when I turned the high idle on, the tea kettle noise got louder and there was some coolant residue coming out of the exhaust (small amount on ground and barely visible white smoke). The coolant dripping didn't get faster or slower. It's about 1 drop every 4ish seconds. My thinking is it's a head gasket, but it's studded. Any input on where to go with this is greatly appreciated.
