1/2 ton air filter leaking oil into carb

Post by treefarmer104 » Thu May 03, 2018 4:50 pm

Just put the air filter unit on the carb yesterday, filled with oil to the oil fill line and started her up - ran smooth.
Shut the engine off and the next day there was a small of puddle of oil under the truck. I could see the carb was covered with dripping oil. I felt the outside and the inside of the filter where it connects to the carb and it was dry. What am I missing? Thanks

You called that right,
I closely examined the lower oil bath unit and found three pin holes just below the oil fill level.
Will plug them with some JB weld.
Thanks USAFpj, I couldn't figure out what was going on.

Treefarmer, I was recently working on my Uncle's 50's Cletrac crawler, and was wire brushing his dent free oil bath air cleaner cup. I had it filled with kerosene and was scraping away some bits of clear silicone goop at the bottom. Once I removed the goop, out went the kerosene :lol: :lol: . I normally advise to spot weld your pinholes up, but where there is one hole, you'd find another!

Glad you got it figured out!
