I have a hard time imagining a 7M that's even missing a few valve stem seals going though this much oil. Also, the 7M's a non-interference engine, pull the keepers and the valve drops in far enough that you're not going to even compress the spring enough to get the keeper back on it. You can use the rope trick to get it done but I don't recommend that to the novice... they tend to scratch and gauge things more than enough when the head is pulled and sitting nice and easily accessible on a workbench.
TSchultz, are you actually burning oil? That mush oil would create one hell of a smoke screen. My recommendation is that you start cheap and easy; Do a compression test (once dry and once wet) and see what that shows. Read the spark plugs (look to see if any given one looks worse than the others). Check the intake plumbing for signs of excessive oil. Inspect the PCV system and make sure there are not clogs and that it's all properly routed to the intake.
Are there no external oil leaks? Has the head gasket been changed?
