New guy, owner of the best 1987 Pickup ever. Small problem though, I believe it's to do with the blow by system causing an oily air filter (and consistently dark oil). Can anyone direct me to some info or perhaps a website with fiches so I can identify the other parts that are oily (and shouldn't be). Thanks all, and looking forward to contributing where I can. Al
Best 87 ever, has probably paid for itself 10 times over and still wants to go. I'm on the north left coast, Vancouver Island. I was just going through my shop manual (which gives bogus information about the location of the signal flasher) and see that my issue is most likely the PCV valve needing replacement. I'll be doing a check on the vacuum systems too though. Cheers
