Hi,

There is a leak around what is called "Oil Deflector" located just behind the crankshaft pulley.
Would you please tell me how to remove this oil deflector?
What is its function?
Thank you.

Welcome to 2CarPros.

I have to be honest. I'm not sure what you are referring to. Behind the crank pulley / harmonic balancer, there is an front seal. Take a look at the attached pic and tell me if you see what you are referring to.

Hi Joe,
Thanks for your response. I've drawn a blue line around the part I'm inquiring about. The oily messy part behind the pulley. I think it's what BMW calls Oil Deflector.
Thanks

On second thought, it may be the oil pan. Do think the leak comes from the gasket. It's heck of a job to replace. If so, can I just use some leak stop to get rid of the leak temporarily? This is an old car, not worth the effort to change the gasket.

Welcome back:

As far as an old car, it's older, but one of the good ones. I honestly never trust an oil stop leak product. Not that it will hurt the engine, but they rarely seem to work. There are some which are better than others, but regardless of product, it is totally based on what is leaking and how bad the leak is.

If you want, I can provide the directions for pan gasket removal and replacement. Also, there is a crankshaft seal that could also be leaking behind the pulley / harmonic balancer. I can give you that info too if you want.

Please let me know if I can help.

Take care,
Joe
