Oh damn...talk about taking a thread to the shidder

Couple of questions:

If the Scotchbrite pad effectively cleans the oil mist out of the crankcase vapours, preventing them from going into the intake manifold, why would it still be a good idea to use Seafoam to chemically scrub the combustion chambers? What would it add? Or is the Seafoam being used in the intake tract, which wouldn't seem to be necessary if the crankcase ventilation system was functioning (however the oil separation is accomplished).

There seems to be a conflation of the issue of valve stem seals leaking (likely related to valve guide wear, but that is just a guess) and crankcase ventilation issues (CCV, catch can, or home made system, whatever)? Posters seem to see the latter as a cure for the former. If there is excessive blowby, there will be lots of oil for the crankcase ventilation system to have to deal with. But I am trying to separate symptoms from root cause here. Do posters see these two issues of valve stem seals and CCV systems as related, other than the fact that they can both happen to a vehicle, independently?

And a comment: If that description of fuel additives actually did apply to modern engines, as claimed, then it wouldn't include a section on carburetors. Just sayin.

PS: Yes, the use of terms like root cause analysis does give away an engineering and mechanic background. In my case, automotive product development and at a different time, dealer service. No apology here for being an engineer. Doesn't seem to go over too well with some.

I think it's combination of both. In my case, I have filtered the lines going to the intake, but that hasn't completely fixed it. I still have some smoke, but nothing like before. At this point I'm assuming ( u know what they say about that) that the valves have carbon build up and aren't seating properly.

keep up the good work billie bob , it`s highly entertaining .

FWIW, If the valve stem seals are shot a crankcase vent catch can will do nothing toward resolving an oil burn issue.

I would put my money on it is a combination of both and that some, because of some much information on leaking valve stem seals, go there before they need to do so. As far as Sea Foam I wouldn't use it for anything, might try it on a clogged drain, or if it was drinkable, but other than that, IMO it is a great formula for disaster.
