excessive moisture in egr valve

[Rawze]

Sounds to me like you might be dealing with someone clueless. Makes me wonder what else that shop might have done incorrectly, half-arssed, or has been guessing blindly at. If some mechanic told me that the EGR valve on a CM871 was the cause of water in the circuit, I would have run the other way as fast as I could.


There are no water or coolant circuits/lines/hoses going to the EGR valve. Replacing the EGR valve would do absolutely nothing towards solving moisture or coolant issues inside the EGR piping except to lighten your wallet of some of your hard earned cash.


If it has been confirmed that it is actually moisture buildup and the system has been tested for, and there are no coolant leaks (similar to this test: https://youtu.be/tNmQnAJzmVo ), then chasing down moisture in the EGr circuits is most likely chasing a ghost for no reason except someone's own paranoia.

Here is another post(s) from people discussing moisture found in EGR and intake circuits...
