Pictures

I haven't seen any really good pictures of the telltale "caramelized goo" that Don says is indicative of elevated exhaust back pressure, so I thought I would add some for everyone's viewing enjoyment. These came off the engine I just bought as a spare. I think it might have had some back pressure issues!

Intake port on manifold side of block. The other one looked the same.


Three of the four intake valve holes.



This is the intake valve closest to the exhaust flange. It was really stuck in there. This stuff is hard to describe. It won't wipe off (without a solvent of some kind), and it's sticky like tree sap, but way thicker.
