Hey everyone!

Long time no post. Been busy with life and such. Long story short, got all the "hockey pucks" and o-ring for cyl head cover replaced. Also replaced the 4 O-rings for the rocker shaft hex plugs. So no oil leaks from there.

Now , we can see fresh oil between the cylinder and the cylinder head. I am 99% sure that it is the two O-rings that are outside the #1 and #4 cylinders. Compression is good on all 4 cylinders, so I'm confident the Head gasket is intact. The only thing is my son will have to deal with a messy engine  until we can re seal the cylinder head this winter.

That which does not kill you, will give you some awesome scabs, which turn into some cool scars!
