Chrysler 318 --- Water in Oil

[p12]

I have recently purchased a 1971 32' Marinette with twin Chrysler 318s (225). The port engine oil looks milky. I obviously suspect it's water. The starboard engine seems fine and shows no signs of water in the oil after being run. <br /><br />I am new to the 318 and fairly inexperienced with marine engines. Any suggestions on what to look at first? Common problems, any items/gaskets that are easy/cheap and should be done first, before pulling manifolds and heads? <br /><br />The boat is currently on the hard, I don't want to pay to have it launched and find out that the block needs to be replaced and have to pay to have it pulled. <br /><br />Thanks for your time and suggestions <br /><br />-Mike Patterson

I am not familiar with Chrysler in marine applications, but....are they closed cooling or raw water systems?<br />Were they properly winterized?<br />A cracked block or a cracked manifold/riser would be my first thoughts....<br />Either way you need to get some fresh clean oil in there......JK

Raw water cooled. I just got the boat so I have no idea if it was properly winterized. The starboard engine seems to have faired okay, whatever that means. <br /><br />I changed the oil last night and am going to wait to try and track down the problem before I run it again.<br /><br />-P
