Leaking Coolant (no other symptoms)

[SJPotter]

I have a 6.0 PSD in my 2004 motorhome. I noticed a coolant leak on my garage floor, not bad but enough to take notice. I climbed under the vehicle and investigated. I found it coming from directly at the valve cover gasket for the right head. What could this be? I have no other symptoms. No oil in my degas bottle, no smoke. I am running the BPD EGR cooler. For cooling my oil I have a custom dual cooler setup as follows: BPD oil cooler in conjunction with a new stock (9 row) oil cooler. This custom setup is a remedy recommended by BPD. The problem was that after having replace the stock oil cooler with their air based oil cooler the resultant cooling proved inadequate for my motorhomes heavy cooling requirements. This fact was drawn out last summer when I had a sever overheating incident in the mountain passes of Colorado while towing my truck with the motorhome. On that trip I was running with just the newly installed BPD oil cooler. I saw oil temps pegged at 255 degrees a couple of times. After that I went to the dual oil cooler setup based on discussions with BPD (Bullet Proof Diesel) After installing the dual oil cooler setup, which consists of the new stock 9 row oil cooler and the addition of a BPD air oil cooler, things seamed fine on my return to Colorado later in the summer, very low temps at all times, I was very happy. but when I returned I noticed the coolant leak. Could the severe overheating have cracked a head? Is that why I am now seeing the coolant leak? Any help would be great. Thanks in advance.

Start with the simple stuff...like the little piece of hose between the BPD manifold and the EGR delete. If it is hose clamped, check the tightness of the clamps.
Coolant will drip on top of the engine and work its way back there and drip off in that area

I don't have an EGR delete but rather the BPD EGR Cooler...But I am hoping that you're right and it is something loose in the plumbing and not a cracked head. Thanks for coming back with that.

Even if that hose is the stock configuration, it can still leak. The ends that click into place have seals inside that can fail and drip coolant.
Haven't heard of a cracked head on a 6.0 that leaked coolant like that, so it is likely just a hose or something similar.
If you can't find the leak, you might have to put dye in the coolant to track it down.

Yes, and it started right after they put in the new oil stock oil cooler so it is probably a plumbing issue. Thanks again.

Im dealing with a similar issue. Mine was leaking coolant from the starter area. Found out it is a cracked head. Diesel leaked into the coolant and ended up destroying some o rings and gaskets. Cant wait to get the bill for this one!

this is a bit of a different situation though. you are leaking coolant because you have diesel contamination. you have contamination because the head is either cracked or an injector cup has failed.

to the op, all you have to do is throw a pressure tester on it. you'll find it within a couple of minutes
