Front head removed and even before lifting it, I knew something was not right
as there were several noticeable markings on the head bolts.
By the way, the V-bank was cleaned to this level. Before/after.
While the level of carbon was much better than the rear bank, the colour of
#4 exh valves and part of #6 were very different from others.
Also, there were unusual deposit left on the #4 spark plug.
By the way, #2 spark plug showed very white deposit and #6 one just
smelt awful.
While the gasket shape could be deformed while I was lifting the head,
clearly there is rusty marking behind.
In fact, it's the section below that the coolant escaped.
And this is what I found after peeling off the gasket.
Several rusty spots observed but glad that the cyl wall were fine with
no abnormal markings.
As always, cross-hatching was still there even after so many miles.
