"I reciently purchased a 1984
"I reciently purchased a 1984 Sailboat with a Volvo 2001. I hired a delivery Skipper to sail the boat to me about 500 miles. He made it 18 miles and had to turn back, stating that the engine had stalled after all of the oil had blown out of the engine through the breather and was now in the bildge. When the boat finally made it to me on a truck, I thought I duplicated the problem. The engine would idle fine but at mid throttle settings oil/fuel would begin to spew from the breather. We troubleshot and repaired a defective fuel feed pump diaphragm and a coolant bypass tube which was completely plugged with carbon at the top (exhaust manifold end), I also installed a thermostat (it had none). I emptied aproximately 7 pints of diluted oil from the crankcase and serviced with fresh oil. I figured that since the oil had become so dilluted with fuel the delivery skipper simply could not see the fluid on the dipstick and assumed that the crankcase was empty. The engine now performed nicely on land (no load) so we dropped it in the water and got one days good use but we only used the engine intermittantly. Yesterday we took it out again this time using only the engine for power and after 15-20 minutes of 3/4 throttle operation the engine died, it would still crank but would not start. After opening the engine compartment I saw that the bildge was full of oil and there was no oil on the dipstick and the breather was still dripping of oil, just as the delivery skipper had described. Once the engine cooled I reserviced the oil and it ran long enough to get back to my slip (about 5 minutes) although at the end it was idleing rough. Any Ideas?
Thanks in advance,
Ron"
