    hi, so here's my questions, and before i start please bare with me. im sure some of these will seem like obvious answers but its just me over here and i wanna make sure i do things right, and please dont tell me to take it to a shop because i know way to much about shop prices, plus my ex took my truck to a shop for this same problem and lets just say they did half a job literally and thats why im here today.
    so about 2 years ago i had to have my coils and spark plugs replaced, easy job right? but for some reason thats when my ex thought $300 was a good deal for a shop to do it. so dumb to me, anyways, they assumed thats what it was, they never ran a compression test or anything, a few months ago the check engine light came on and the engine started shaking, i ran the codes and got multiple misfires on cylinder 3 and 4. my ex was gonna take it back to the shop, but that didnt happen, i mean fool me once right? anyways i ended up changing the coils and plugs again because when i got in there they had only changed half the coils and they had diff gaps on the plugs, it was a mess, and the coils were fried, i tried to run a compression test at home, but my ex took the truck and decided it was fine because the check engine light was off. hes an idiot. anyways hes out of the picture now. thank god. but like i said from the beginning you have to find the root of a problem or it will re-accrue. and it did. the check engine light is back on the engine started shaking again, no codes this time though. not yet at least. i dont have the equipment to do a compression test here but i did a very thorough search and lo and behold there is a crack in the pcv valve. probably could have saved lots of time and money if people just did there jobs. or i could be wrong and it could have nothing to do with it, but i think im right because after reading more on pcv valves it makes a lot more since as to why this is the 3rd time my check engine light has came on the first 2 times do to misfires, and there was leakage in one of the spark plug holes. i just ordered new seals and a new valve, i actually have plugs and coils coming too but now i dont think i need those, my main questions are, am i even close to being on the right track? and if so when replacing a pcv valve do i need to replace the valve and the hose attached as well? or is there more then that even? and do i need to replace any specific coils or censors or anything if im replacing a valve? and lastly, i read somewhere about stuff called oil sealer or something to help seal where oil is getting into the spark plug holes? should i look into that?

    I can't speak to the rest of your question but you should not need to replace the hose unless it's damaged. You should only have to replace the PCV and possibly the grommet it sits in.

    Here is a thread on the subject.

    any CEL codes the vehicle has now, CEL codes cleared or pending?

    but yes I would replace pcv, hose and grommet, they're usually really hard and break up when removing so careful not to let bits and pieces fall in...

    Just replaced mine, had evidence of blow by the valve at the grommet onto the valve cover. Valve and grommet replaced, reused the hose, still felt fine. 254k miles on the truck.
