Hello! I own a 08 Acura TL that has an oil leak from a bad valve cover gasket. I took it to my mechanic for some other things, but also wanted a quote for a replacement. The number they gave me was too high for my liking, and I did some research and decided to attempt the replacement myself. The shop would’ve done a spark plug replacement as well, so I also plan to do that. My issue is I have never done work on a car, not even an oil change. In total so far, I need 2 sets of valve cover gaskets, spark plugs, an intake plenum gasket, and maybe an air filter boot (since I’ve heard they have a tendency to crack, if anyone has a good source please let me know). What other parts should I preventatively replace, and what are the normal steps to working on the top of the engine?

    I would say Honda coils are darn reliable and if you aren’t experiencing a problem, don’t sweat it. They are easy to replace if that time ever comes. I’ve had a couple DOA aftermarket coils and certified parts were stupid expensive.

    The plug boot mostly just keeps dirt out of the plug hole. It can degrade if the spark plug is failing allowing some blowby to heat things up.
