Beckett ROCB-072 oil leak
Hello everyone, I had a new system installed 18 months ago. No issues last winter at all. This winter, I am seeing a slow leak at the burner casing. There also appears to be a slight backflow of oil where the burner meets the air inlet. Once the cycle shuts off, a very small amount of oil rests at that connection point. Once the next cylce starts, it will be sucked back into the system.
It takes a couple days for the oil leak at the casing seam to get enough to drip onto the floor. So this appears to be a very slow leak.
Any thoughts on what may be causing the issue? The annual heating service was completed about 3 months ago, with no issues. If any other photos would be helpful, please let me know.
