oil leak... from opti...? Ok so I have a oil leak which I thought was from my front seal, Well I changed the seal and still got leak. But now it looks like its coming from my opti and seem to have a misfire. Is this possible,can oil be leaking into my opti and causing the misfire.
There's 3 seals in the timing cover- water pump drive, opti, and crank. Most often the oil leak is caused by the water pump drive seal- directly above the opti. There is a seal that the opti slides into also though. If you buy the timing cover gasket set it should come with all the seals you will need. I would take the opti out and take the cap off and see if there's oil inside it. Search on here for tips on replacing the wp drive seal. If you're not careful it will leak as soon as you put it back together.

oil migrates down and may "appear" the leak is coming from the crank hub seal you replaced but that seal is not the most common "front" engine leak. If oil is gathering and driping from the opti it most likely is wp drive seal or front intake gasket.
you really need to pull wp & opti and look and since you have it off replace both those seals. they are all in the FelPro front timing cover gasket set for around $10
yes oil will get "inside" the opti so you will have to pull the cap off and possible even dissesamble opti to clean oil from it.
pics below are from a wp drive seal leaking that did not drip on ground. uually oil slings around from accessory belt and you notice power steering slip. when I pulled the opti there was a "slight" sign of oil gathering on the bottom of it but you can clearly see oil got inside the opti. this can also clog up the valves in the opti vent harness...

you can clean the oil out, I did and it works fine. been on the car for months now. My opti did not have any stumble or issues before I pulled it. just could see the oil collecting on the bottom of it
get a AC Delco/Delphi opti
also use a "tool" to put the wp drive seal on. socket, sharpie pen cap or the "tool" itself (pic)

to install the wp drive seal just use the coupler from drive to wp itself. sand the couple smooth and use light oil and slide the seal on. slide it on the drive shaft and then use a socket to fit over the coupler and tap the seal into the cover.
