FAQ for Oil Filler Cap Repair

Q: What is the service procedure for diagnosing oil leaks in extremely cold temperatures?
A:
You need to inspect for the oil fill dipstick being pushed out of the dipstick tube and that there is engine oil seeping out when the engine is under operation, replace the oil fill cap with a vented oil fill cap if icing or freezing condition is found with a PCV valve inspection, use a new vented oil fill cap, and inspect the engine oil level.
