This car has the IPD updated front and rear seals. It also has IPD swaybars, magnetic oilplug, a IPD valve cover, and a few other "goodies."
I've degreased the engine several times over the summer. The gunk seems to build up pretty fast with highway driving, but I'm not getting any "blow-back" such as when the mainseal went in my regina 745, or when the front seals and oilpan seal were leaking in my 945. Both of those events left an oily film on the underside of the car and on the rear window. There is some oily gunk on the underside of the body, but no film on the glass. Unless the mainseal went out since I got the car back from Texas, it's fine. I replaced the gearbox in May, and there was no leakage. The Oil loss pre-dated that repair, so I think I can rule it out.
I think I'm losing it from a number of places. I can see a small dripspot under the oil drainplug (I fear it is nearly striped, so I hesitate to tighten it anymore). However, that drip is kinda intermittent. There's some general oily gunk around the oilpan gasket, around the mechanical fuel pump seal, and around the PCV oil-trap. There is usually a tablespoon or so caught in the valve cover fin right behind the filler cap.
One thing, is that with oil burning I expected to see fouled plugs when I was pulling them for the compression test. They had a little carbonization on them, but they looked pretty good - a nice light brown glazed appearance, a little bit of soot, but nothing too serious. What should I have seen if I was burning oil at that rate??
