Hi all,

I am trying to fix engine oil leak on my CRV 97. I replaced the oil and put a new oil pan gasket. However it is still leaking oil somewhere. I took to repair shop and they said it might be damaged the crankshaft oil seal as it leaks around the crankshaft pulley.
I removed the pulley and took a few photos. I would expect if the leak is from cranksahft seal, there should be more oil inside the cambelt area, but there is not that much.
What do you think?

I also checked the PCV vavle as somebody mentioned it might be the air pressure inside the block. The PCV vavle is rattling.
Where else the leak can be?
I appreciate any idea.

Thanks
Martin

Actually a good chance of it otherwise it's higher up the motor.

When you see and oil leak you always go up the motor till there is no more wet oil. Don't start repairs at the bottom, follow the mess upwards.

Remove the top timing cover and look down, only thing on that side under the cover that leaks is the cam seals. (have to remove the valve cover)

And the PCV is supposed to rattle.

That looks about as much as my crank seal was weeping and it's only going to get worse, I replaced mine, relatively easy job. Though you have left the washer on the crank, pull that off and then post another pic that shows the full oil seal, it should be bone dry.

If you replace the seal only use an original Honda part or find a bearing shop that sells Japanese NOK high temp oil seals, that's the Honda OE seal supplier.
