No oil light came on, no check engine came on until the engine completely blew due to oil suddenly leaking from faulty crankshaft seal. I have had regular oil changes and ALL scheduled maintenance done and nothing was detected. They found the problem when I had the engine pulled. It was sudden, not slow. Strange.

I started losing old. I got under there and change the oil myself to check out the problems. I notice all running down the front of the engine after it rains couldn't really tell where it was coming from. I checked again after it had dried up and noticed that it was coming from the crankshaft seal.
