Thread: Recent FE390 engine rebuild engine smoking problems solved I believe.

Hello folks. I think that I finally figured out why my engine was burning oil and smoking so much after my recent rebuild. There appears to be 1 small thin port next to the #7 and #2 intake ports on the heads that when you look in them you can see the exhaust valves for those cylinders. There is also a port on either side of the intake that match up with these ports that seems to be some kind of possible air cooling passage for the intake. Not sure though. I also found a small hole in the intake that was letting oil into the passage via the lifter push rod hole. The passage was filling with oil and I think that oil was also seeping behind and getting sucked in behind the intake gasket at the port openings which in turn were being dumped into the exhaust port of #7 which was then getting blown out my exhaust. You could see the oil in the ports when I took the intake off. I'm not sure why there are no holes in the gaskets for these ports though. I do remember when I got this car most of the top end was in the trunk. When I went to clean up the parts, I'm pretty sure there were 2 thin pieces of metal stuck to the intake on the ports in question to cut them off. I'm ordering an Edelbrock Performer intake to replace this old Weiand but it also has those ports. Anyone know the best way to go about plugging these puppies? I'm not sure why these ports are even there if they are not to be used. As always, thanks for reading my post and offering your knowledge. Appreciate it very much.
