Any marks on the piston tops on the exhaust side?

Pics below show shiny exhaust valve rims on 2 and 4 and tiny witness marks on pistons 2 and 4. I was as close as it's possible to come to foobaring my ST.

no marks on pistons or valves

just done another leak down test this time filled the inlet ports with fuel and exhaust ports leaked through number two valves and slight leak from numbers three valves have taken one of the inlet valves out of cylinder two nothing obvious so think i will try re lapping all the valves cost of rebuild £63 so think i will do this before buying a new engine

[keith kelly]

may have just exasperated an existing issue with the engine. I did read somewhere that and st engine required some valve adjustment after over reving so worth looking into

[tractor]

didnt over rev it limiter set to 6500

[keith kelly]

Oh in that case sounds like existing issue

[tractor]

i have had all the valves out ahhhhh 16 and the exhaust valves on cylinder two were very coked up so just doing another leak down test and hopefully that was the problem

[tractor]

and wot a great bit of kit this is made life so much easier

[keith kelly]
