It will be louder if your timing belt tensioner is shot or loose, but I doubt that's your problem.

I know it gets louder as you put more miles on our oil. After a fresh change it's quite quiet. After warm up it's obviously more quiet than when cold. Or one straight friggin' cold days it's sometimes a hideous sound.

Default tensioner

It's probably the tensioner. Some clicking is normal, though.

ok ive got a little over four grand on my mileage, you guys really think its a tensioner?? and yes this ones to (((ciper))) i tried mobil 1 10w30 because i did research and alot of peopler where using it and it worked great, esp for hotter climates because im moving to Arizona soon, but then i switched back to 5w because... well ... my friends running 280 to the wheels on he's wrx and hes been using 5w30 and its fine, and i dont think it would screw anything up with that transfer because..... Full synthetics viscosity are diff to regular oil, its basically insense thinner so there for even if ur using a 10w30 full synth in ur 5w30motor it shouldnt mess it up because the oil is still able to flow through its passages. AMEN!

P.s i know on higher horsepower / modified vehicles, its good to use a thicker oil because of the build up of friction and impact do to the heavy modifications ( and yes i wrote this high so most likely.. i must be pulling things outa my head )

Did you buy the car new? I see your running fully synthetic and only have 4,000 miles on your car. When did you switch to full synthetic? I know this is arguable, but I wouldn't switch to full synthetic until between 5-10,000 miles. Maybe your valve chatter has something to do with the engine being broken in improperly. But, like everyone else said, it's probably the tensioner.

His using synthetic oil has absolutely nothing to do with valve noise. Nor can anyone produce more than heresay evidence that switching to synthetic prior to XXXX miles is a bad thing. The reason being, there's no reason to wait.
Take a good look at your manual... it says quite clearly that you can use synthetic, provided it meets all the requirements set out (i.e. service specs and weight).

For every "my buddy told me that synthetic is bad if you blah blah blah", I can produce actual chemical analysis reports that make it rather obvious that the only difference between synthetic and conventional oils is that synthetic is more resistant to breakdown. Ergo, there's nothing about synthetic that will not allow your engine to break in just like it would on conventional oil.

I've run synthetic since 1700 miles. I've got over 8000 on the car now. It runs the same as always.

before this turns into a "battle of oil thread"......just wanted to say.....i've began to notice my valves are making a little more noise then usual...i'm at 43k mi.....all my maintance has been kept up perfectly....oil changed at the same interval, all filters swap, u name it, i've probably done it already(in terms of maintance)s

i've actually just noticed it the other day...didn't think too much of it though

You guys suck. No more talk of synthetic or conventional please.

MidNiteImpreza: Try the 10w-30 and wait 100 miles or so after filling, see if the noise changes.
You dont need to explain oil to me. It also doesnt matter what horsepower your friend is running. I know plenty of people running huge power dont filter the air, why dont you do the same?

Everyone has to learn somewhere and not everyone has time to read and search every post on NASIOC. Ciper is a good guy, he has helped me out with my questions a couple of times. But yes, that did seem kind of rude. Not everyone is equally knowledgeable.

Correct me if Im wrong but......I dont think we have hydraulic lifters, and, if we do they are meant to be "shimmed" which would lead me to believe it is a mainteance sort of thing.

Im making this assumption after quickly referencing the service manual, there appears to be a procedure for checking valve clearances, and replacing the stock shim with a thicker one.

I remember drastically improving the sound of my 84 bmw 318 after using a feeler gauge to tighten up the valve to rocker arm clearance. Its not quite as easy on a boxer motor.

Is this something that will probably need to be serviced but subaru conveniently leaves out of the maintenance schedule?

Is this the sound that the old Subarus I see/hear are making? Or is that a timing belt tensioner thing?

You guys are too sensitive. I wasnt being rude in my post, just blunt.

Whatever, no help for you then.
