    Pull your back 2 spark plugs and have a look too. Dead giveaway if you're pulling oil through the pcv. I'd bet on valve seals personally but yeah, who knows.

      My '88 has mysteriously stopped burning oil. I haven't had to add any in 1,200 miles. Straaaange.

          How about leaks? Seems like those would dry up with nothing left too...

            My valve covers leak but I don't give a shit. Not enough to make a big difference and that motor's going bye-bye anyway, someday.

                Make sure the bolts on the valve covers are tight, I've had a couple of engines with loose vc bolts (loose enough to turn by hand). Weather someone had been in there before (very likely) or they just loosened due to engine vibration (less likely?), I'm not sure.

                  My '85 LTD's were so bad it dripped oil all over the exhaust manifolds. Stinky.

                    I cleared up the leaking valve cover gaskets when I changed the covers earlier this year.

                      If the valve cover bolts are loose, its usually because the cork gaskets have shrunk. Cranking them down usually splits the gasket and makes it puke even more. Change the gaskets, don't mess with the bolts unless you know its a rubber gasket.

                        I recall when 347's first started becoming mainstream and something about how the oil ring on the piston was intruded by the wrist pin. Some stroker kits didn't have this "feature", while others did. The wrist pin intruder ones used a special support for the hole left by the wrist pin. No problem if you don't have those style pistons, and no problem if you do but have the support. But if it got reringed at some point and someone bought standard rings, that could be a problem...

                          basically the wrist pin sits up into the oil scraper ring and oil just goes behind it?

                            This motor has always had non-cork gaskets for the covers.

                              That wasn't necessarily directed at you, just a general mention. I have a pair of cork gaskets here, they've been hanging on the pegboard in the workshop for years. I have no idea where they came from but they're not going on anything. I have a spare set of Permadry hanging around just in case I need them. On clearance at Rockauto at some point, so I snagged them.
