I think I have a major problem. My l988 3.0 started getting water in the number one cylinder and oil. Had the head tested, as well as the manifold and elbow. All were done by a professional shop. Head gasket showed no water tracks. Replaced all gaskets as put back together. Still water in number one. <br /><br />Question--any way to test for a cracked block?<br /><br />Just how big of a job is it to replace one of these motors. I can borrow the tools (hoist/stand) etc. The clymer book makes it sound simple (perhaps too simple) Would appreciate any advice.<br /><br />Ps the boat is a l988 bayline capri with about 600 hours on it used in salt water. Is this beast worth the effort or am I putting more money in the hole.<br /><br />Thanks, Tom
