Is this normal?
Hi guys, it's been a while. Hope everyone is doing well! Well I have an H&S tuner and AFE exhaust sitting around for 3 or 4 years wondering why I bought them, but I finally decided to do the delete! So tonight I was disconnecting the EGR and EGR butterfly valve connector and took a look into the butterfly valve and was really shocked to find so much soot! I took the butterfly valve off to get a better look. There is seriously between 1/4 and 3/8 inch thick coating of dirty soot on the valve, and further into the intake manifold looks horrible.
I know the EGR system returns some soot into the intake, but this seems ridiculous! The truck has about 33k miles on it. It's stored in winter, and about 2/3 of the miles are cross-country summer hauls with the 20k fifth wheel.
Please see the photos. Any feedback or advice is greatly appreciated!
Thanks,
Carl

You would have to remove it completely from truck to clean properly.

Thanks for the replies guys. I really appreciate it.
Imagine if a big chunk of that stuff broke off and was swallowed by the engine! Intakes should be clean. I'm going to clean that all up.
