We have: Bilge from any point in the system including the water heater Exhaust via combustion chamber Exhaust via raw water from an internal heat exchanger leak Internal leak in the water heater (yuck!) A leak someplace in the manifold that dumps into either the intake or exhaust A leak someplace in the recovery tank
I think we got to 6 now. A pressure testing cap for the heat exchanger should find many of these. I cannot emphasize enough to CHECK THE OIL. I know more than one person who was puzzled by an inboard engine GAINING oil and then soon after was buying a new engine. It was water in the crankcase floating the oil up higher. If you run it like that the oi whips up into brown foamy goo that does not lubricate well at all. I had one such engine and we drained the water out each day until it died for good.

Check the oil for coolant contamination ASAP and check the exhaust for excess steam and/or white smoke. The bilge should be obvious ;) Joe Della Barba DCSI 410-966-7255 From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Bill Coleman via CnC-List Sent: Wednesday, May 13, 2020 9:34 AM To: cnc-list@cnc-list.com<mailto:cnc-list@cnc-list.com> Cc: Bill Coleman <colt...@gmail.com<mailto:colt...@gmail.com>> Subject: [EXTERNAL] Re: Stus-List Loss of coolant Not in a 3JH4E, but I did in my Olds Custom Cruiser Wagon, with one of those 350 Modified Diesel Engines. Those were not up to the task which I knew going in, but I just loved that car. It was common for warpage at the head gasket, I think the coolant leaked into the oil, tho it may have gone out the exhaust, I don't remember anymore. I just remember loosing the coolant, and several hundred dollars.

I motored for 14 hours and it lost 5mm of depth in the reservoir. The reservoir is approximately 4" DIA. I checked thoroughly for visible signs of leaking and found none. Has anyone had this experience? Glenn Henderson WeGo C&C 41
