RE: 3W 106 adjusment issues -- "balsa box?" -- RTK?
If the leak is just a "little" wetness (moisture spot), it should not be a problem. If the pulse pressure is blowing thru, it must be fixed. First check to make sure ALL the bolts on the whole engine are tight. Loose head bolts have been known to break. Where abouts on the front of the engine is it leaking???
In the end it should be fixed anyway. I hope the machining on the casing is true.
