The one that costs $15, you have no idea what you did.
Well then it didn’t have anything to with the valves being dirty. Sounds like that can of Motorvac was full of confirmation bias…
Great addition and suggestion
the things I suggested might still be good for preventative measures. It's great to be able to see, but sometimes when it finally gets noticed it can become more of a pain. UOA,we do this to see things before hand and I feel the three I suggested do have a place; at the very least the GDi spray and pea fuel cleaning as some of both of these will make it into the crankcase. 
Maybe, I have over 325k on the suggestions I posted and suffer no issues so I simple suggested what has been successful;at least to me. If he's got a turbo, it can only need it that much more. These are only my humble opinions and I'm okay with what everyone else does. My experience in putting two K24 Earthdreams engines combined millage into the sum of over 900k miles on original motor and transmission has to count for something....maybe not all, but for someone it will.
One works, one doesn't. I wouldn't be overly concerned with IVDs unless you having misfires etc. I did my VW at ~75K and it wasn't bad at all. I'm pushing HPL 5W40 Euro in a turbo VW with ~200hp/L including tracking it and I'll be doing a ~10K change this year.
I am just saying what is the best. If you just want to consider chemicals, then yes, some are probably better than others. However, you really don't know what effect it has. Does it peal off some CBU? Perhaps. Does it clean it all? Absolutely not.
I agree that preventive maintenance is always good practice. My comment was just spured by what is the best. If someone wants to do through cleaning, this is way to go. I agree, most people want things just to work in order.fair enough. can we agree if it gets to that point, might as well upgrade to titanium valve springs and retainers during the disassemble?
I'm not looking to the absolute, only what the average Bob on this forum wants to do to keep it running. I might add a catch can too but if it's driven enough and up to temperature on a regular basis then it's possible like in my application that walnut blasting can be avoided hopefully. again, I enjoy your input and enthusiasm but most people try to do as little as possible to keep it running in fair condition. I always said if mine got to that point, I'm going for a piston upgrade with coated internals. I think what we can all agree on is preventative maintenance in some aspect ain't a bad idea.
you are driving it like you stole it. Great for the EGR and PCV systems. Blow by might be your issue, but you already are ahead of that. Has Liquimoly offered you a job yet??
No they are upset with my coup d'é tat to HPL.
with good customer service. My only complaint is they are in a draconian state.I don't think I'd characterize the standard suite of Euro approvals as "bottom of the barrel".@High Performance Lubricants is miles ahead from LiquiMoly on performance oils. I like a couple of LM additives but they can't come close as HPL isn't restricted by a specification oil thats merely a bottom of the barrel suggestion. The products at HPL are mind blowing
I would. Why do you buy from @High Performance Lubricants ? Because you want something better,right? I'm just really starting to see where these companies aren't chasing after a price point but a performance point. Enthusiasts who live,work,sleep,dream,etc cars demand more. I can't fault them because I am one of them and it's a niche group and we pride ourselves of giving our cars better stuff.
Sure there can be better but a Euro oil like M1 0W40 for example is hardly bottom end stuff.

I’ve found it really useful for looking around cars. It can see inside things, or behind things, in a way that even a mirror can’t match.My understanding is with GDI engines it is always a problem. How bad of a problem is the question.
Geez, another tool I gotta get! Maybe I can use it for medical experiments too....
