Hi all,
I’ve run into a concerning problem with my rebuilt 12G940 cylinder head and was hoping someone might be able to help me out. I ran the engine for the first time without coolant for a few minutes to bed-in the head gasket and then let it cool overnight. My plan was to retorque the head and adjust the valve clearances before the 20 minute cam break-in period. When I went to adjust the number 4 exhaust valve, I noticed that it is stuck open resulting in a considerable gap between the valve and the rocker. All seemed fine during the initial run so I am at a loss. Any advice before I remove the head? Please help! Thanks in advance.
