Well I finally got around to cleaning my valves (theres one for you sickos lol), looked better than some of the photos I've seen, some valves were worse than others obviously. New gasket was also put between the IM and block.
I tryed metho (as recommended by Cobb ie. denatured alcohol) and found it didn't really do anything, I left it overnight as well and vacuumed out the next day.. The best thing I found was Nulon throttle body cleaner from Repco, left this for an hour, or overnight where I could and vacuumed it out, got most of it. The rest was cleaned using steel brush extensions. Keep in mind I don't have an air compressor or walnut blaster, if I did it would've been ten times easier and quicker. I have also installed new injector seals (for those wondering you do not need the 'special' injector removal tool, I had 3 stuck injectors and wiggled them all out by hand (thanks ax)) and an oil catch can onto my horn bracket so will be interesting to see what it catches. Yet to start the car (fingers crossed) will report on any butt dyno impressions...
For reference, this was cleaned around 88,000km
