lokito50, I've since added some photos of process as I performed procedure.Hi again,
Are you guys doing this to the rubo version? I was taking a peak at that hose posted in a picture earlier and it leads to the turbo?
Maybe I'm wrong. Anyone with the turbo version care to post some pics indicating where they sprayed this can? I would greatly appreciate it.
I did on that Isuzu second engine but you have to think of this like heart disease or something. If you're neglecting things and then try to fix it up after the fact, that's when you may notice some difference in performance/metrics, but at that point it's likely that you need to unbutton the engine and do some mechanical cleaning and see what you have going on. If you use this as preventative maintenance, which is what it's designed for, then you should not really notice much difference. When the neglect is pretty bad, you'll definitely see the difference and you want to avoid that...$$$. PEA isn't going to keep it spotless clean but it can prevent buildup to the point that valves aren't sealing and thus may burn or start a snowball effect.Out of curiosity, along with these treatments, is anyone actually monitoring the before/after PID's like fuel trims, misfires, flow rate, MAP values, O2/AFR values, compression... etc. to see if the cleaning actually made any sort of difference? I'm all for keeping intake valves clean but if the measure of success is "it feels more responsive", how does anyone know if it actually made any sort of difference? Again, not trying to knock cleaning the intake and back-sides of valves. I have both my SFS and HS hooked up to a catch can so I recognize the caking is a problem. I see that I'm getting delicious looking stuff out of them but have no clue if it's making any short term, long term or even noticeable difference.
This is very interesting considering how much catch cans are being championed as the best solution. It reminds me of some research I saw posted on the bobistheoilguy forums a few months ago (I’ll share if I can find it again). The findings saw a much higher rate of deposits on engines using full synthetic exclusively, which was fascinating. The post was a couple years old, but I’m surprised it didn’t generate more discussion about the general best practices for gdi engines.https://docplayer.net/38978662-Cons...tion-in-gasoline-direct-injection-engine.html
Positive crankcase ventilation(Blow-by) was not related to carbon deposit formation
This is pretty scary because so many believe their c̶a̶t̶c̶h̶ condensation cans are doing something positive. I'd consider these three ideas. Condensed fuel is wasted fuel. Captured/condensed oil could benefit engine as upper cylinder lube. Water vapor could reduce detonation/preignition like water injection.
Since condensation cans, with their plumbing, can decrease PCV flow, it can increase oil contamination by not allowing enough fuel/moisture/vapor to vent. So, one must weigh the pros/cons. This is why none of my cars run catch cans.
