Default 105k service, taker her in for valve clearence check or diy valve job

I have all the proper tools for the job including an engine hoist to pull the engine, but I've never put new valves in a head before, other than an old chevy 350 engine. At the moment my valves make a lot of the standard subaru clicking noise and im wondering what you guys think I should do in this situation. Car has 106k miles and Im wondering if I should take her to a dealership to get the valve clearence check (if anyone knows the price of this, that would be awesome!) Or should I just get new valves, springs and retainers and do the job myself with a buddy ?

I also lack the measuring tool to do the valve clearence check.

Ok so with 106k miles on my engine and lots of valve noise do you guys think it would be a better investment to just do a diy valve replacement job ? I did a little research and found bc valves, retainers and springs for a total of around $650. I know I would need new seals but those are cheap, anything im missing ?

you are missing the fact that the valves almost certainly dont need to be replaced

why do you insist that the valves be replaced????

many of these motors are(well) past 200k miles with the heads never been off the engine

adjust them and see what happens

if you do a leak down and they are out of spec after you adjust them...THEN start thinking about pulling the heads

Just out of curiosity, when I took my 2005 WRX in for it's 105k maintanence "package," I don't recall seeing the valve adjustment anywhere in the "to do" list. Uncle Scotty, am I missing something?

well...there are issues with these cars having the valves 'get tight' over time

sometimes this causes valves to burn because they dont seal up when they get older

these engines just make a lot of noise...lots more than many are used to and they think there is something wrong when there isnt anything wrong

Ya I know the clicking is normal on Subaru's. I guess im just being a little to cautious, I tend to do that a lot. Car still runs like it did the day I flashed stage 2 so I'm not worried that the valves are causing any real problems. A leak down tester and air compressor are two tools im missing from my aresenal, but my buddy has a compressor I can use and, since I have a compression tester, might as well pick up a leak down tester.

Is it possible to adjust the valves with the engine in the car or does it need to be removed ?

what oil are you using????

these cars seem to shear 5w30 to 0wPiss in about 1500 miles....and using a better NON 5w30 oil helps the noise issue for many of us

I have over 100K on my WRX and don't hear any valve ticking. Using thick oil can lead to cold start wear and engine noise imo. I'd rather use "0wpiss" in cold weather and prevent start up wear.

Im using rotella T6 atm, I was using thicker oil when I first got this car but did a lot of research and T6 seems to be the oil that most swear by on this fourm, and I have had good experience with it so far. I was thinking about sending my oil in for an oil diagnoses, I have the kit at my house just need to fill it up and send it in.

I use rotella t6, car still ticks as usual and my uoa is perfect at 84k. So no real worries.
