Hello,<br />I am new to this site. Appears to be very complete and helpful.<br />I have a 92 Four Winns Freedom with the Volvo/Penta 3.0.<br />Ran it about ten minutes last summer and discovered water/oil mixture coming from carb.<br />Marina said it is most likely a cracked block. There was not any water in the bilge. Assuming it is internal.<br />I have read a few different things on the internet relative this problem. Some say head gasket; some say block and on this site exhaust bellows. Marina sounded pretty confident that head gasket problems are rare with this motor?<br />I've learned that you just don't call Jasper and get a replacement.<br />A new GM longblock is $1900 plus!<br />I am looking for anybody with experience dealing with these motors and if the marina is correct in their opinion that it is the block.<br />Thank You...
