Re: milky cylinder
Yes there is a gasket between the plate and the block. There is a chance it may be leaking. Never seen one leak as there is a lot of gasket material there. If water came out of the head bolt hole when you removed the bolt, I would suspect a bad head gasket. I would think that the head gasket should seal the bolt hole from water. Anyways, check for a hairline crack in the cylinder wall. If you can't find any, put a new head gasket on and test first. If you still have a leak, I wouldn't pull the power head until you try replacing the exhaust cover gasket first. It's not uncommon for it to leak. The gasket is pretty narrow and doesn't have a lot of surface area to get a good seal. NOTE: Use caution when removing the exhaust cover bolts. They're easy to snap off. Depending on how much corrosion is on the threads. Sometimes they come right out, other times they're a major pain. If you find one that is stubborn, tap it lightly with a hammer.
