Powerhead pulled. Exhaust manifold removed. (Fyi. Exhaust manifold on a sportjet is a very interesting beast)
It appears that the exhaust manifold has been compromised. As shown by the area circled in yellow.
This part is very expensive I have it on order now.
Question now is would this create water signs in JUST cylinder number 2 and a cyl miss at high rpm?
Could water be sucked out of the water jacket in the exhaust area, then get pulled into the cylinders? (water pushing backwards into running engine???).
I understand that a two-cycle engine doesn’t completely clear the cylinder of combusted fumes but I didn’t think they would find their way back in.. much less find their way back in mixed with water?
