I have a 1983 Bayliner Capri 19' with an AQ125a/270. I bought it in about 1999. At that time I pulled the engine and outdrive, put in a new sole and transom, had the cylinder head rebuilt (he knurled the valve stems instead of putting in new guides which I was not too happy about at the time). This boat has only been in fresh water. I fog the engine every winter, open the drain plugs and the raw water pump. I cover the intake to keep mud daubers (wasps) out. Then, each spring, I fake a lake by attaching a clear vinyl hose to the intake, sticking the other end in a constantly overflowing bucket (I keep the hose running), and I replace the plugs, set the timing, change oil etc. It has been a great boat.
Well this year, when I de-winterized it, I did two bad things. I got distracted and forgot to take the tape off the intake and I did not put the intake hose back on the pipe that leads to the transom. In short, no raw water was coming in. It ran great until the coolant got too hot and the cap on the expansion tank let off a cloud of vapor. I looked at the temp gauge and it read 215. I realized one of the things that I had done, raised the outdrive and removes the tape.
Then I did another stupid thing. I restarted the engine thinking I could cool it now that the tape was off (without hooking up the hose--didn't notice it; didn't even think that I probably had trashed the raw water impeller by this point-duh). Then I goosed it a little to rev it up But I forgot to lower the outdrive. This process bent the shaft in the tilt and cracked socket where the tilt fits in the transom shield. [Stop laughing.] After restarting, it could not have run more than a minute. Thanks whoever you are that towed me in right away without me even asking.
Back in dry dock (my driveway) I replaced the raw water pump impeller, and warmed up the engine (it ran fine). Then I did a leakdown test using a two gauge OTC leakdown tester and compressed air and all 4 cylinders in the warm engine were within one or two PSI. I got a new transom shield on Ebay, and pulled the engine and outdrive. I thought I could just put it all back together, but read on.
When I pulled the engine, there was greasy soot on the outside of the exhaust pipe and sooty oil in the engine compartment on the exhaust side--not a lot but it took 10 big hunks of paper towel and zep degreaser to get it up. I have never had this in the bilge. It has always been clean. I also notice that the bucket that I used to catch the exhaust water from when I ran the engine had a thin film of oil in it. Never had this before.
One more thing. Two years ago, I forgot to open a drain **** and two freeze plugs were pushed out. I replaced them and ran it for two seasons with no trouble.
So, what do you all think? Where is the oil in the exhaust and in the engine compartment coming from? Remember the engine is still out of the boat, so, at this point, it is pretty easy to do about anything. Although the #%$^ gaskets and parts for putting this back together are making me think. Should I pull the head and send it to the machine shop? This is my first post. Thanks.
