did the vacuum line method (twice)... That was awesome (the looks I got)...
I think I need to do it again though... Lighter color blue smoke was coming out after a while -- at first it was a massive white cloud that was still rising over the rooftops, driving out of the neighborhood... I think I'll keep doing it until the blue smoke goes away (obviously oily dirt washing out)
This rig had the valve cover gaskets replaced just before I got it & maybe that was the 'hot' smells I was smelling?... after the seafoam, not smelling it much now.. Hope further treatments well help further....
And yes, I was able to notice the difference in idle (absolutely)... can't feel anything when it's running now... (over the last few weeks I've been able to detect a slight roughness coming back -- after the plugs / cops were changed)
Also have a thought (just a thought) on driving it out on the road vs. letting it sit at idle & rev the motor.. I only got the massive cloud when I drove it... 1st time at idle didn't do much at all... Probably better to drive, making sure all that crap is 'exiting' the system, rather than possibly building up a residue somewhere?.. just a thought...?
