My engine refused to start after a sail. While try anything to get the engine started again I removed the sparkplugs and discovered that there was water between the contacts. I dried the contacts several times, shut off the water supply but no luck. I ended up having to call for a tow.
I deducted that it had to be a crack in the head since I had replaced the gaskets a couple of years ago.
I removed the cylinder head and noticed that there was water on top of the valves for the fourth piston. The piston housing also had rust stains I sent the head to a machine shop for magnafluxing. They found a hairline crack on the top running from the left side around the alternator block but the block inside showed no sign of a crack or leak. I have include a couple of image showing the crack and also the condition of the exposed block.
Regarding the crack, I was wondering if anyone had any welding done to a cylinder head?
Also, what other areas of the engine could cause the water to enter the pistons?
