Cam/Head Swap Disaster.......

Almost what I said.......I said water does not have any compressability.....remember? I made the word up? I'm no scientist, so yeah I may be wrong. In other words what I mean was oil is slightly compressable compared to water.......but that may be bad info too so ?
Hey Rusty, I'm pretty sure the reason folks were disagreeing with your post was due to the "compressibility of water and oil" statement. I am a scientist (oddly enough), and yes you were wrong about that on the level that matters in this discussion...but hey, no biggie, live and learn, all is well. I won't get into all the mumbo jumbo behind it, but as a general statement, they are correct.

Now if you dive deep, it gets a bit more complicated than that (dissolved gasses and what not)....
