Back from the dead.

Removed the LIM and the biggest affected cyl (#2) is dry at least on the intake side. I'd expect a bad head or bad valve seal when I get it off and to the machine shop. Per the last diag I hope rings can ruled out. But too much oil could have killed them. But I don't know. Besides that the entire LIM is slightly damp with oil. Is there anyway to prevent this? I have a hose from the oil cap to the air intake tube after the maf.
