Engine has a good bit of sludge in it that I'm trying to clean up so I'm running Mobil 1 and on the last oil change added some Seafoam. Pulled the passenger side valve cover (and the valve cover, cover) and cleaned everything up. The opening for where the hose from the intake goes was plugged so I cleaned it up. I will get around to the valve cover on the drivers side over the next day or so. Anyway, since cleaning this port this weekend I'm getting alot of smoke upon acceleration after sitting at idle momentarily. Is the fact that I've only done one side so far causing it to suck oil up like it is?

When I pulled the valve cover, cover I noticed that oil is pooling in this area which explains where the oil is coming from and it is quite evident it is going to get sucked into the intake at idle when the vacuum is high. If you remove the excess oil in the area it pools in the area I have shown (circled). Is it supposed to have a level at this area? Should the area circled be letting oil drain back through it? With all the sludge breaking loose it would not surprise me if it has allowed this return port to plug.

thanks
