I have an 88 OMC 3.0L that I have been having a VRO issue with. When I bought the boat last month, the motor had just been rebuilt and only had 8 hours on it. Since I have had the boat I have been getting random VRO alarms. I have done a lot of searching and reading and realized that every one has been very adamant about using the proper clamps on the lines. So I ordered the proper clamps and was installing them. When I got to the engine compartment, I took the line off of the oil side, and fuel started to drip out. This VRO is brand new, they replaced it when they rebuilt the engine. Could it be defective? From all the diagrams I have been looking at, it doesn't seem like fuel should even be able to get into the oil side. If any one has any advice, please it would be much appreciated.
