I have a '84 240 wagon with 350k-ish. I did the 'Robert DIY' test for my PCV system and it failed. It involves holding a glove on the open oil filler while the engine is running. If the PCV system is working the glove gets sucked flat; if the system is clogged the glove inflates. My glove inflated. I pulled off all the PCV components and made sure they were clean and free and I cleaned the throttle body making sure all the little ports were clear as well. It didn't fix it. I haven't had a problem with oil seeping out past the seals and the dipstick hasn't popped out either. I put this all before the congregation; do I have a problem or not and if I do what should I do about it? PS I changed the oil and filter while I was fiddling with the car.
