My LS1 has 102K on it and I followed the writeup on using seafoam... blew out a bunch of white smoke after pouring it through the vacuum line as expected but after 100 miles of driving with half a bottle in the crankcase the oil is still amber clear. Not quite what I was expecting...
I did pull a valve cover off a few thousand miles ago and couldn't see any gunk built up, the aluminum just had a varnished color to it. I was hoping it would clean that up but we'll see. Anyone else ever have this happen?
