Good tip re TDC that should work fine, I'll try it today.
The valves are not wet, the deposits are just shiny, might be how I took the picture. I poked a dry tissue in and it came out covered in black soot not oily.
Still waiting on a cleaning brush set similar to Keith's, so today I'll remove the PCV short pipe, measure up for the hoses and Catch Can and get them ordered.
