Took the intake manifold off tonight. The backs of the intake valves on cylinder #1 are soaking wet with fresh Oil. The other cylinders are bone dry. all valves were taken out checked and new Viton seals were installed a couple of weeks ago. Me thinks the machine shop that did the work messed up or missed something.

Yeah, the point I was getting at is that (assuming his cylinders can hold pressure) if he really wants to check the seals and guides without having to pull the head he can pressurize the cylinder to hold the valves up and pull the valve seals that way.

I already did that with a Leakdown tester and was very good and both leakdown and compression was even on all cylinders.

I've been toying with the thought of doing mine by pressurizing the cylinders with the head on the block. Problem I have is that I don't think my rings will hold enough pressure to make this feasable.
