PCV valve problem

[kevinv]

I have a 91 civic HB standard, 1.5 sohc. Was smoking very badly but intermittently. Was told it was the head(valve seals). Put on a rebuilt head. During the process found the PCV line completely blocked with dried sludge. Replaced line and pcv valve. Did not however check the metal box on the side of the block to which the pcv line is connected. I assume that is a baffle to let the lower end breath while keeping oil out of the pvc line. Anyway, car started right up, ran very smooth, the idle was a little fast. Within a few minutes it puked oil out either the front main seal or pan gasket. Checked the operation of the pcv valve by squeezing the line, does not appear to be working. Also noted that when I take the oil cap off the idle changes. First question is what is the metal box on the side of the block that is connected to the pcv valve? If it is clogged up would it cause enough pressure to build up in the lower end to force oil out the main seal, or blow the pan gasket? The car does not leak oil continuously, only after the motor has been started a few minutes. Any help would be appreciated.

It's a breather box for the pcv system. Better make sure it's not clogged up. If it can't breathe at all, the pressure is going to continue to build and eventually something will blow out.

Ahh hell.

Title says it all. Did my valve clearance, all went OK, then went to put the cover on. The torque wrench was set at 6 lbs, spec is 7.2. I was on the second pass, when CRACK! one of the bolts breaks off halfway into the head. I'm assuming getting it out is just a matter of drilling the center out a bit, then using an ez-out or something similar?

Right now the gasket is on and sealed with 4 bolts, and I even put some honda-bond sparingly around the area where the busted bolt is supposed to seal. I'm just going to drive it as is, and will just expect a little leakage for a while. Anyone have any suggestions or an easier way to get the stuck portion of the bolt out?
