well after an afternoon of pulling valves and changing seals, the valve stem seals were the problem. from what i could see they were original and never had been changed. they were all old wallowed out seals with little sealing ability at all, could see the oil where it was getting sucked into the intake past the valve stems. i recomend to any one changing them, bc not that hard to do and heard most go bad after 80k. rent spring compressor and follow directions in manual. i used the rope in the cylinder chamber verses the compresed air. worked great, just make very sure the rope is actually under the valves or you can still drop one in the chamber if not carful. i know, lost a exhaust valve luckly got it back up. and make sure you get a good valve compressor makes it alot easier. now in the process of changing clutch out, the last dummy who put a new one in changed out the transmission seals and put them in backward, dont really work that way. oil all over clutch. thanks again for the info everyone.
