Looking for any that are handy enough to remove their intake manifold and take pictures of the coking levels and include your mileage at the time. Anyone needing any instructions just let me know.

So A shop would charge how much to do the anti coking of the valve stems?
Varies. I see anywhere from $600 to $1200 to do a manual cleaning. And few have been trained properly to date. I like the way this member did it. Very detailed and effective:
You absolutely need to make sure the valve in the port your working on is closed so no debris or solvent can enter the cylinder, and that all other ports are taped off as well to avoid any debris entering them. When finished with one, clean, tape off and move to the next. Turn over the engine to ensure valve is closed with a socket on the crank pulley bolt (I think 7/8" if I remember correctly). If you do this document all with pics so we can all get an idea on the average coking level at X amount of miles.
While I had mine apart to install a ported throttle body and intake manifold, I took these pictures of the oil in my Elite Engineering dual valve catch can at 1500 miles since last emptied (a little more than 2 ounces), and my throttle body. There was also a smear of oil around each of the intake ports where the manifold meets the head. The car has just shy of 6000 miles and I empty the catch can of about this same amount of oil at 1500 mile intervals.
It's not an invitation to join the thread. Its a link to one post. Your post and pics with oil in the intake even though you have a catch can just reinforces my point.
Your point is that catch cans are not 100% effective. My point is that I would rather filter out a large amount of oil than have that extra amount go through my intake, across the valves and into the combustion chamber. I'll take some filtering over no filtering every time.

the problem is any oil on your valves is the same thing as a little bit, especially with a DI motor. pointless mod unless you eliminate the intake suction and thereby eliminate the entire source of the problem. if you think otherwise you are just lying to yourself.

Another picture of oil being drained from a catch can, and yet no pictures of the valves.
yes catch cans catch something. but that oil being put into the engine. We dont have enough data on the LT1 if its even that bad for the engine. Hell i really wont care if oil is chilling around in the engine or being burnt away if it doesnt hurt anything. or it takes a lot time and miles to cause damage.
on top of that. the pictures being posted are from a BMW n54/n55 which are known to have terrible build up.
Nobody is an expert in this area. I have yet to see any horrible coking.
Here is a picture of mine after 12000 miles.
Everyone knows Higgs redirects the debate to an unrelated and highly personal level. Therefore, just left him go and chose not to wrestle in the mud with him.

Thanks for the picture. Is that black stuff carbon build up? Looks like a very thin layer, probably isnt causing any power loss.
Why do you always feel the need to be such an a**hole?

as I have said before, if you were local, I would help you in any way I could and give you as much of my time as needed as I do for anyone. I am not here to hurt your feelings and just because I commented in this thread and you happened to be the last person to comment before me doesn't mean it has anything to do with you.
just because you posted an example that illustrates a point I made a long time ago doesn't mean it's personal to you. I don't know you at all, I just see the pic you post and the description you make. why does that hurt your feelings?
I contend one doesn't need a catch can and am prepared to make my case but you bought a catch can already so I am an a**hole.

I see I can add condescending to my earlier assessment.
