Well, got my compression tester down and since this morning was fairly cool and breezy I decided to get that intake off and get at it. I did some errand running to get the engine nice and hot (FSM says 60-80*C for test). Parked it and 15-20 minutes later I've got the intake off and ready to do the test.

Welllll, it's not as hot as I though it was going to be and I don't feel like digging into this any further, so it's being relegated to parts car again. Oh well. it's got 3/4 tank of diesel so I'll drive it out and start stripping her and add another data plate to the collection.
