I listened with a statoscope and isolated sound to Cylinder #1.
When removing the plug for that cylinder, the noise goes down but does not go away.
I guess not a good idea to run on 7 cylinders
Went to change oil, and it came out gray, looks like super tiny oil flakes in it.
I did not bother cutting oil filter open as I don't think it is needed due to the condition of the oil.
A little bit of a bummer, we finally have our 2nd warm weekend of the summer and it looks like the boat will have to be parked and instead of enjoying the water, will need to yank the engine out.
I'm debating it is it worth replacing the road bearings or just order a new block...….
