96 850 non turbo/ oil under the top cover
I take the top cover off to expose the plugs and there is a lot of oil there. Where could that be coming from?

You need to replace O-rings in the spark plug wells. It needs to remove the camshafts cover. If you have no experience, you better to entrust this work to mechanic.
If my English is bad, please correct me

is the oil in the spark plug wells, or is it in the recesses along the cover? If it is primarily in the plug wells, see the above response, but if it is in all the recesses of the cam cover, especially between #2 and #3 cylinders, it is most likely from a bad oil cap seal, or the PCV hose. Either one indicates the need for PCV servicing that you will find in other threads here. When the PCV blocks up, pressure builds inside the engine, forcing oil/vapor through the weakest seals, how is the inside of the distributor behind the oil guard?

I think FLXC90 pretty much hit the nail on the head with oil cap seal and PCV needing service. If you search PCV system you will come across posts on how to evaluate your PCV system and also how to do the service. Member RSPI has several excellent videos on this issue.

go to the repair database and search the pcv maint. It will run you through all of it. You'll save the $15 by disposing of the flame-trap, but there is a little more to it than just that. Did mine recently, big difference.

Nothing. Remove it and put the hose back in to the throttle body hose - the "flame trap" is just a plastic disc that fits inside the hose that serves only to clog.rogreact wrote:If you throw the flame trap away what do you replace it with? A piece of hose? I am a novice
