Default loud ticking noise! :(

i just got the car a few weeks ago and it is my first subaru i have had. i was told they are louder then most other cars ( ticking wise) but this seems a bit excessive. it isnt really there when i am just sitting there if i rev the engine up. but under load when excelerating, it is pretty loud. i dont think its knock becauase its not low of a sound to be knock. would the timing belt tensioner make this sound? what are some ways to check the tensioner to see if its bad?

Is it constant or does it vary with engine temperature? and do you know the maintenance/ ownership history of the car? that info would be helpful

You just got the car......its 7yrs old.....it's time to do some preventitive maintenance.

It would be good to have the valve clearances checked and adjusted if necessary. Depending on milage, timing idlers, tensioners may be needing attention.

There isn't really much in the way of specific subaru traits other than the boxer sound and what some people think are loud fuel injectors.... Have it checked out by a mechanic knowledgable in subarus.

...oh, and congrats on the purchase!

forgot to mention, i have replaced the spark plugs and have done the valve clearance twice to make sure got it done correct. it has about 145k on it.

i have also replaced the exhaust manifold gaskets.

it has the normal loud kinda piston slap when first start when cold, most that goes away when warm, but the noise i am talkin about is still there when it is warmed up.

i dont know the A LOT of the maintenance records but he did show me some of the stuff he had for it and all the stuff was done at subaru. like oil changes and such. all at 3k each time. but other then that, dont know.

Your best bet is to take it to a mechanic who works on alot of subarus or make us a video and post it on youtube, if we can hear the actual sound it becomes alot easier to diagnose.

I'm not saying you have something bad, but when I had a bad bearing, it would rattle for about half a second on startup(no oil pressure yet), then come back when warm. I'd say to keep going on the tensioner path for now. I can't help you on that, but search.

my car had a wrist pin let loose at 135K on it, it was a light ticking and now sounds like a knock, but it could just be the fuel injectors.

subaru injectors are quite loud, get a long screw driver and put it to the block and the handle to your ear, move around until it gets louder or quieter, and you will find where its coming from.

it sounds like its coming from the front of the engine. could this sound even be the tensioner? or would it not make the noise when warm and excelerating.

also, i noticed it does make the noise in neutral a bit when reving it but not as much as when under load.

sounds like a spun bearing, you just described what was wrong with my subaru when my engine spun it's bearing! take it in ASAP!!!! i ended up having to replace my complete short block and complete heads! due to metal shaving getting ALL over the place.

Cold weather = ticking noise. The ticking should lessen and go away as the car warms. In very cold temps, the ticking may lessen but sometimes not completely go away. After switching to a low base synthetic (ow30, 0w40) for improved cold weather driveability, I've noticed the tick seems to be less, but I don't know why.

I can't comment about other "noises" specifically. Because it is a new car to you, you will find various sounds you are not familiar with. This sort of makes everything suspicious.

A spun bearing is a pretty specific sound. You get a lot of physical movement between the parts and start getting definite clanging between parts. It's a pretty obvious sound generally. You'll hear it quite audibly with the car just sitting and idling.

Just some little tick, tick, tick while the car's sitting there may be very little. Then again, it may grow to be something big.

Try and record some audio of it if you can.

when my car spun it's bearing, for a month prior to it fully going. it was just a "tick tick tick" at idle, when reving up between 2,5K-3K RPM you can really hear a tick tick tick. then a month went by and i was on the freeway when i gave it a little gas and the next thing i heard was "ping pong ding" and my car dies completely and wouldn't start up again.


so moral of this story! TAKE IT TO YOUR MECHANIC OR DEALER SHIP ASAP!

drain the oil and look for shiny, copper bits. you may have to shine a bright light in the oil pan to see them. That's a definite sign of bearing failure.

sure can, the crank pulley only drives the PS pump and a/c compressor. i would keep the pulley on after removing the plastic covers.

It also runs the alternator, so make sure you don't run it for too long, but you should be able to find (or not find) a problem well before the battery runs out.
