ABSOLUTELY REPLACE THE CRANKSHAFT SEAL AND MAKE SURE WHOEVER DOES THE TIMING JOB REPLACES IT. Even ask for the old seal back.
I learned the hard way. Paid premium prices for a timing belt and water pump. They didn't replace the crankshaft seal, but said they did. Oil was leaking out. Found a mazda tech. They knew the problem on the spot, replaced seal, and gave me the old one which still had the original mazda part numbers.
Pros: original mazda part numbers
Cons: oil was leaking out
Vehicle:
Mazda
