Well my engine has been burning massive amounts of oil...about a quart every 200 miles. There is a lot of blue smoke when I start it and when it's running you can see some all the time.

I checked all my plugs a few weeks ago and the #4 plug was pretty oil soaked so I pinned this as the trouble cylinder.

I did a leakdown test on that cylinder and an opposite cylinder that is good and the readings were the same so I think that ruled out bad ring or valve seal.

So I spoke with my engine builder and he thought it was the intake gasket maybe. So I spent 4 HOURS today removing my Super Ram and intake and the gasket was perfect....now the car is apart until my new runner gaskets come.
The intake ports all looked perfectly clean including the #4 problem cylinder. Only theory my buddy and I can come up with is maybe the valve seal is bad and it's drawing oil right down into the combustion chamber when it's open and the gasoline is washing the intake port down so there is no trace of it. Since I have the valve cover off (which is a PITA) I think I'm going to change both valve seals on that cylinder. Hopefully when it's back together I won't have any more smoke.

Anyone else have any ideas on where it could be burning from?
