Where is this oil coming from?

I noticed some oil puddles the other day on top of my timing cover. I cleaned them up and today they were back. Where is it coming from?

Does oil get up to the top near the dizzy and would that much be getting up there? I can't figure out where that much oil would be coming from.

are you 100% sure it's not coming from the timing cover? Not sure where else it would come from unless it's the valve cover some how?

I've had coolant in those spots, but not oil...

I have no idea. I'm up for any suggestions. Does oil go through the timing cover? I don't remember any oil ports, just coolant passages. To me it looks like it coming out of that suspect bolt.

Oil goes through the timing cover to keep your timing chain lubricated.

Another possibility could be the front seal where the lower intake meets the block or maybe a leak from where the O-ring goes around the distributor?

try tightening valve covers probably not the source but possible

front cover

you are right, oil does not go THROUGH the cover, but it is on the inside of the cover for the timing chain, etc - as mentioned above. The timing cover - by far - I think is most responsible for this, but you'll have to investigate to make sure. I don't know of any way to tell except to look for an oily place on the gasket or a break in the gasket where the cover/block meet.

I don't see how oil would get that far up in the distributer hole, but I suppose that is a possibility as well as the lower intake and the valve covers I mentioned earlier.

Good luck and let us know.

The heads and the front seal under lower intake are clean, and I put a new dizzy o-ring in when I did HCI about a two months ago, but I'll look closer. It could be the front cover since I replaced the water pump about a month ago. Would a leak just develop all of a sudden like that?
