They knew all about it leaking where it did before I sent it up. I thought seal was gone inside and filling up cavity and leaking out bolt hole. But I kinda knew if it leaks when running it probably leaks back air causing hard start. So I sent it to Wilkinson diesel in Regina, so only needed a housing not a whole overhaul, they said it didn’t leak on bench testing. Maybe it didn’t but it leaked there before it went up and back. But they are like everybody else stick it all on the farmer if they can. Don’t appreciate the business.
