How does one determine if this procedure is needed?
Can a borescope be used, or is there major disassembly required?

There are detailed DIY on the site. Spark Plugs and intake manifold must be removed. You can check with a boroscope. See here.

You guys mind sharing how much RMP charges?

Would it be reasonable to do this to a NA N52?

I had mine done at just over 50,000km at Toronto BMW under warranty

The bill would have been just over $1,200

If you find someone local let us know because the next time this service will be out of pocket for me

If you don't want to take that chance, there's another guy that is mentioned in the same thread (Ivo @ Columbus Automotive) that comes highly recommended. He does it for $350 as posted and is in the GTA.

PS. Leslie = Amazing

You can tell off the bat that he treats the car like his own. People were nervous, myself including with the significant discount compared to the dealer. He blasted my intake valves and even did my throttle body yesterday, immaculate job. My carbon buildup was atrocious, and he went above and beyond to make sure the job was done and done correctly. Not enough kind words to describe how professional and re-assuring Leslie was. Would trust my car with him anytime of day, and will bring it back for a JB4 install.

If you're near Mississauga you should go see Ivo over at Columbus Auto. He's a class act and charges fair prices.
