I guess what I'm asking, or am at least surprised by, is that the painting step would even work. FF seems very oily (I've used it in small areas) and I'm surprised that paint would stick to it.
Interesting angle. From a cost perspective, it's cheaper than a timing belt replacement.
Except Toyota with their DI+PI scheme.
I understand anal. I'm really curious to see if the catch cans help. I've read arguments that there's enough oil leaking down from the valve guides that removing the PCV contribution won't solve the problem. (But will it slow it down?)
I can't help but think that either: (a) everybody on this thread is wrong and all this oil won't lead to actual deposit issues, or (b) GM's going to have a huge mess on their hands in a few years.
If (b), what will their response be?
I wouldn't go for more than a year if my only driving was to church on Sunday. You'll get moisture in there, especially given that you're in MA with winter and all. I suppose you're keeping an eye on it with OA, but without that I just wouldn't go for more than a year.
The veracity of your statement which I bolded is what I'm trying to figure out. I have no argument against it, but I still want to see evidence.
There are fewer vehicles without DI available each year. By the time I'm ready to buy, there may be none, or at least none that otherwise interest me. I'd like this problem solved by then. How will I know?
By March, there's way more sand on the roads in MA than there is on the beach!
More on-topic, while it's clear that the cans catch a lot of stuff, is there any evidence that it stops valve deposits? (Has anyone put one on one of those Audis that have really bad deposit issues and seen the issue fixed?)
