What type of cleaner would y'all recommend before taking anything apart? Marvel's mystery or kreen?

I will be digging deeper into this problem over the weekend.... Previously before this problem that I have I did replace the upper intake with a used one out of a junkyard. I replaced it due to the throttle body bolts being over tightened and cracking the intake. Could that have possibly have anything to do with it. I did clean the top and replaced the knock sensors while I there.... It had your typical dirt and grime. If I can find a picture I will upload it.

I bought it used two years ago and it was regularly maintenance, I did a Carfax check on it and have previous history on it.... Since I owed it I've done my own oil change on it, usually every 5,000 miles but sometimes a little over. I've always used 5w30 oil and what ever oil filter AutoZone gives me. I will definitely pull the hose off of the Pcv and see if that is clogged or something.

Not 100% sure if its an lq9 or not. Just 2 thousand over 200,000. And yes I do have oil in the intake. Not a lot but pretty noticeable.

Okay I have an 06 GMC Sierra 2500HD 6.0 Gasser. Here lately for the last few weeks now I have been having to add 4qts of oil within a weeks time. I also have blue smoke upon heavy acceleration and once the truck is warmed up at idle it'll smoke faintly. Recently did a compression test on the passenger side and everything checked out good. Ran out of daylight so I wasn't able to do the driver's side yet. But just curious and wanted to pick y'all's brain about what could be the issue. Valve seals or the rings, I don't think my year model has a changeable PVC valve. Which one would be the best case scenario lol. I'm hoping that the truck can make it until taxes because I'm a single income household so if I can maybe fix the problem myself that would be great. Thanks in advance.

So I have a 06 GMC Sierra with the 6.0 gasser with the 4l80e. I am throwing the p1810 code which I am pretty sure is due to my forward clutches being stuck together (I'm getting the transmission rebuilt very soon). So my question is, will this code cause the truck to not rev past 2500 rpms at idle? It shifts fine and goes up to the normal rpms while I'm driving. It doesn't say that I'm in limp mode but kind of feels like I am. The truck doesn't really have any get up and go and it feels like I'm always towing something. I'm thinking maybe fuel related, but with the transmission code that may very well be the problem all together. If anyone has any in put I would be interested to hear, it's a boring rainy Sunday so I'm just reading up on the codes.
