I noticed that there was oil and gunk in my inlet pipe and some parts of my air intake. See photo attached.
From what I've checked online this is also what goes into the combustion chamber and causes buildups on the valves. This in turn can also lead to poor fuel economy such as in OPs case. I wouldn't be surprised if the buildup on mine is going to be bad. Perhaps in such situations a walnut blast followed by the adding of a oil catch can might be beneficial.l as opposed to waiting till 200k kms.

Catch can was one of my first mods as I figured it would help with how much junk gets recirculated back into the engine.
