Plenum or rings?

Plenum or rings?
I have a 2001 1500 with the 5.2. I'm pretty sure I need a plenum gasket, I see oil in the intake through the throttle body but here's my question. I'm fouling plugs about every 5-6000 miles but just 3 of them. They have oil on them when I pull them out, the other five look to be in good shape.
The engine has 200K on it but runs good with new plugs. Could the plenum gasket just be fouling the 3 plugs? I'm not sure it's the same 3 every time or if it is 3 every time. I just noticed the oil when I changed the plugs yesterday.
I'm going to do a compression check as soon as I can find a gauge, what should the compression be?

If you have oil in the plenum, then you definitely need to fix that first. Do you have serious oil consumption problems? (mine was going thru roughly three quarts a WEEK, and it gets driven less than 100 miles in week......)
Real possibility that the plenum is the major contributor to fouled plugs. Compression test won't tell you how good your oil control rings are though.... As for the test itself, anything over 100 pounds is considered 'acceptable'.... all cylinders should be within 25% of each other. (which seems like a LOT of variance to me......)

Yes, the plugs are at the rear of the engine. The engine also feels like it's running under a strain now too. I've started to notice some oil burning but not sure how much yet, I keep check on it though.
I'll change the plenum first. I'm ordering the hughes gasket kit, that's pretty much a permanent fix to the plenum problem isn't it?

And don't use the PCV valve from the parts store.... I made that mistake, and my oil consumption got WORSE, even after the plenum fix. The aftermarket valves seem to have WAY to high of a flow rate, so, you suck oil right out of the valve covers. Get the valve from the dealer. Ended my insect-fogger-like behavior.
