Bent push rod?
Anyway we returned to the UK and have done a number of flights since then with no problems indicated.
Couple of weeks ago and shortly after departure and in the cruise the display for #2 disappeared from the EDM and the engine started running very rough with a lot of vibration. Returned to the airfield and the local maintenance outfit had a look and found a bent push rod on #2 cylinder (and also the the outer tube was bent). This was clearly the cause of the fault in flight and I guess the valve was sticking.
Has anyone experienced a similar fault and if so any advice out there on a possible cause would be much appreciated?
Note: For the last couple of years we have only carried out an oil change on the aircraft's Annual (fly about 70-100 hours per year) - previously we used to do it every 50 hours, could this be a contributory factor to the bent push rod?
Thanks in advance.

Re: Bent push rod?
The symptoms you described are call "morning sickness" and started out only when the engine is cold, and eventually happens in flight. Reaming the valve guides per SB388 is the cure.
