I intend not to remove the head for now even though I have an extra head that I can send to the shop ahead of time. If it's only the seal then I will be happy to postpone a major repair for another time after I go back and control my priority list of things to do in life. The 190E has taken up a lot of my time fiddling with the CIS to no avail yet the problem was much simpler (I think).
Now, how about them tappets/hydraulic lifts?
