Intake valve cleaning

yeah and a forum member who WAS running powell v3 had same issues as me is working on a dual mishimoto catch can setup. IMO it's far simpler to just clean them every other year than to worry about hoses, vacuum, fittings, etc. I guess if you want all that complication sure, but I don't really want added complication.

I've been thinking about eliminating my Powell just for simplicity and doing the cleaning every other year. Did the shells before, might give the GM top cleaner a try. I would imagine I'd need to get a spare valve cover for parts to get the fittings seeing as how the Powell uses AN fittings to replace the barbed pipes, and I'll just need to get new hoses from GM. I cant remeber how they go lol. Anyone change back for any reason recently?
I hate to break it to you, but I had powell V3 (the one that modifies the PCV stuff) and it looked marginally better, but I had 10k less miles. And we're not alone.
I recently swapped an LDK into my car and decided against PCV changes. I'd rather run the stock pcv and clean after 30-40k than constantly worry about a complicated setup and leaks and filters etc etc. There's tons of GM cars out there with no solution for this, I think being proactive in cleaning is the only true solution (without getting into custom multi can setups). Simplicity > all else. Mine's a DD, I feel much better not worrying about it.
Also, GM Top Engine Cleaner works wonders, costs $17 on amazon, and you shouldn't use the whole can (I didn't when I cleaned mine at 113k miles). I rinse with carb cleaner but didn't feel comfortable cleaning with it around valve seals.

Corner of VC -> Turbo
Center of VC -> Intake Tube
The center valve cover to intake tube is the stainless braided line; the old part was replaced by part 12635643. CED is no longer an option as Tom seems to have abandoned the old site in favor of a new site, but you should be able to go into any GM dealer and order that part. It's 1/2 stainless line and half plastic flex hose, much less stress on the intake tube.

Who wants to clean my valves? Pretty sure they've never been done and I have about 122k miles on it (converted for you Yankees and your faux pas of a measuring system).

Sorry about bad quality, couldn't get enough light in to see them. I also had a leak in the line going to the turbo, AN fitting wasn't tight. My can had a **** gasket too (swelled WAY up) and leaked a bit at the can. All in all, it was a fun experiment, but I like the simplicity of it not in my engine bay. The last pic shows the valves after 110k no cleaning, then cleaning with GM Top Engine Cleaner and toothbrush. I made a youtube video of it, just search LNF intake valve cleaning.

Is this problem entirely because of PCV into the intake? In other words, if we vented to the atmosphere, would this all go away? Assuming everything else is in good working order. Not that I'm even considering this.
