I am very good at troubleshooting and finding root causes of issues, which is a hard learned skill that can be applied to cars even without initially knowing the details. Just gotta know what questions to ask and be able to correlate issues to figure out which ones are related and which are unrelated.

    Thanks for the answer on what a PCV valve does. I'll remember this one.
    In other words, you really do not need to know how the things work, just be able to other think every situation?

    It helps to have a good memory to learn as many details as possible.

    My 1990 Pontiac Transport had a PCV valve and I think my 1986 Fiero GT did as well.

    yep, introduced in the early 60's as a required emissions system.

    Its been a weak link in repairs for a long time as its normally a neglected item to be changed. For those with poor upkeep on your basic oil changes normally lead to oil leaks prematurely due to the change in crankcase pressure. I would normally replace them every 30k or so even though they were still clear, at 6 bucks a pop and 5 minutes it was always worth it.

    Thats another thing, years ago engine seals were a rope style seal, then it went to a fitted neoprene style seal. now most rear main/cam/crank/oil pump o-ring seals are combined elements with rubber/silicone/spring inlayed.

    I'm sure most of those older vehicles have leaky rear mains. lol
