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?
Don’t be afraid to try this if you can follow basic instructions. Cars are pretty stout and unless you do something crazy this should go fine.
I would guess you can find some good YouTube videos that will walk through he specific steps/process for your car. Or a car forum/FB group to search any specific issues changing valve covers. Generally this is a pretty straightforward job.
I have no idea what maintenance has been done previously etc. But if it has plug wires might consider changing them as well, however a lot of cars today have coils right on the plugs so no maintenance needed if yours is like that.
Realize the small bolts holding the valve cover on will not take a ton of force to tighten. They’re small bolts going into small holes. Pay attention to how tight they are when taking them off if you don’t plan to use a torque wrench to tighten them. Make them snug not crazy tight.
