I have a oil leak at front of engine.
I cannot pinpoint it but i see a oil mist because by spinning of drive belt and pulleys. I see mist mostly from idler pulley area.
Whole front area of engine is wet from oil. Crankshaft Seal failure?

Good morning,

Yes, it is possible.

I would start by going to a self serve car wash and clean the front of the motor. then run the motor and see if you can pin point the exact are that is leaking.

Hey Roy,

I have already cleaned engine with degreaser and Brake Cleaner multiple times.
Cannot pinpoint leak source.
I am going to replace Crankshaft seal.
Thanks!

Okay, you are welcome.

Always glad to help.

You can always add some oil dye to the oil. It will turn yellow at the source of the leak for you to view.

Great idea! I will do that!
By the way, I am replacing timing belt as it is overdue for change.
I am wondering why my Haynes manual tells me to remove upper Intake manifold and valve covers and loosen rocker arm bolts?
None of YouTube videos, etc, mention these steps for timing belt change.
Should I create a new post for this question?

No need to remove the upper intake and the valve covers. You do it all from the front.

You need a special puller for the lower pulley. It is very tight. Without it, you need to remove the condenser and radiator to access a puller. You can rent one at a parts store.
