I have an update.
I have idled my car as described above for 65 hours and every other day I have driven app. 20 miles to fill up gas and have boosted multiple times during the drive. What is interesting to note is that even though I set my boost controller to 6 psi, it would only go as high as 4.5 psi by 4k rpm and then taper to 0 by 6k rpm. After reaching the 45 hour cleaning mark, the boost could only reach app. 3.6 psi and it would only do it at 4.5k rpms before tapering off again.
The really interesting part comes today when I went for a drive and during one of my boost runs, the gauge hit 5.5 psi and held it to 6k rpms! I thought something was wrong with my gauge because when I subsequently boosted again, it did not hold that much boost. It resorted to the usual pattern. Well, I kept on driving and after a few more boost runs, it held 5.8 psi to redline! The car felt alive again! But as soon as I slowed down and had to do a 3 pt turn, the boost never rose to that level again. Now, it doesn't hold more than 2.9 psi at 4.5k rpm and it tapers even quicker to 0.
Mind you that the valve cover gasket is leaking massive amounts of oil.
I am going to start the rinse phase now by idling it as I did for cleaning but for ~24 hours with interspersed driving and boosting.
My hunch is that the rings temporarily became unstuck as the sludge softened up resulting in temporarily restored compression. And I would venture to say that the subsequent lower boost levels reached after the multiple boost runs means that even more sludge is being cleaned off leaving less of the false seals to seal the ring packs.
What do you think guys?
