Just rebuilt my throttlebody(89 fbird, 305) due to burning oil. Of course it was clogged once again, and things went fine for about a month. Then I started burning oil again. argh. Plus my oil pressure is all over the place, this never happened before and seems to be worse when the pressure drops. Doubting it's my valve seals, any ideas, pros?

 

You built your TBI unit or the whole engine? What was clogged? A clogged TBI won't cause you to burn oil. Bad valve seals usual will result in a lot of smoke during cold start-up and initial run.

 

Exactly!
