Well...after last tuesday's dissapointment, we started talking and discussing of what can be wrong with the engine. It has to be something in the valvetrain area of cilinder# 7. That's where we found a bent pushrod (intake valve).
What if the pushrods that where initially installed where incorrect and are too long. Could this mean that they will "squash" the lifters so they act like solid lifters? We don't know. We're going to check on that next week.
There was some good news: the new headlights fit like a glove. They have different lenses because of Dutch Law regulations. Also, the handbrake-cable which was touching the exhaust when enabled, is now fixed.
