My car is due for a valve adjustment.

I have the Haynes Manual and factory workshop manual PDFs. I've read through several threads here and watched some YouTube videos so I'm ready to give it a shot.

I know that I'll need a gasket set. With my car I'll need to drain the intercooler...not a big deal...but I'm also thinking about what I should do while that is removed.

I've read about the plastic elbow at the cam oil tube, part number PCG115708. Seems like that is something to change while I'm there.

I'm thinking about replacing the spark plugs, last set was installed January 2019...7 years ago already. I'm running NGK B8EGV but it looks like those are NLA.

Anything else?

Any particular tips in terms of the valve adjustment itself? Also probably time for a new feeler gauge...any recommendations? Offset, straight or doesn't matter?

I also run those B8EGV, check them out and clean them, might not be worn if you havent driven it much. I think the BR8EIX and BR8EG are the replacements nowdays, but im not fully deep into the current plugs, the regular non racing ones are the B8ES, probably would also work.

Regarding the valve adjustment, i use a tiny little 1/4 ratchet handle, makes adjustment very easy. Be careful that you dont bottom out the adjuster to deep into the lifter bucket. I just use the normal feeler gauge set.

Plastic elbow is worth a swap if it hasnt been done, can save the cam. They used to be dirt cheap, but not anymore, so the brass one could be worth a shot.

check all the hoses above the intakeif anything is dry, throtle body oring etc while your there. Valve cover gaskets can possibly be reused, depending on when they were swapped
