While troubleshooting wires for my landing light yesterday I found this issue. Number 4 cylinder primer line was binding with the oil return line. They were eating each other, and I don’t know how long the have been like that. I can see that they were wearing each other out and eventually a leak would have developed. Double check your primer lines. Now I’m looking for new lines if I can find them.
