Been there got the tshirt. Backing into a 172 trailer, dollied up and took off, only to see the trailer flop down like a dead fish. Well suffice it to say the landing legs on 172s are not capable of lifting the trailer, only supporting it. So it was hours with bottle jacks and cribbing to get...

PCV valve and vent line from the top of valve cover.
Steam tube on the head which has something to do with water flow at severe operating angles
Oil pan on mid 42 and later trucks have the second lower oil pan, again to...

The vacuum line is the super important venting line that sucks hot ionized air out of the distributor. Without that venting happening, the points and coil will burn up.
