voyetra8 Posted March 11, 2006 Share Posted March 11, 2006 Hey all, Did some searches on this, but have come up with multiple answers. Looking for guidance before I make an appointment with the dealer. Went for a drive up to Maine with my parents today, and noticed a ticking sound coming from the engine at low speeds, mainly when climbing small hills. (Lots of windy roads in Maine.) Anyway, I noticed it, and a few seconds later my *mother* mentioned it, so it's defintiely noticeable. It's not loud or severe, just a gentle tick tick tick tick tick that goes away when you take your foot off the gas. Valve lash? Ping? Timing belt tensioner? Standard boxer engine sound? For what it's worth:10k on the car, and just switched to Mobil1 a few days ago, and getting well below board average mileage. Any advice would be greatly appreciated.

derffred Posted March 11, 2006 Share Posted March 11, 2006 did you check your oil level? Link to comment Share on other sites More sharing options...
voyetra8 Posted March 11, 2006 Author Share Posted March 11, 2006 Yes, oil is fine. Forgot to mention that I have heard this before, mainly when leaving toll booths or drive-through windows. (Basically whenever sound is reflecting back into the car.) Link to comment Share on other sites More sharing options...
derffred Posted March 11, 2006 Share Posted March 11, 2006 if you're in neutral at a stop and rev the engine.. do you hear it? or is it only when moving.. Link to comment Share on other sites More sharing options...
-TT- Posted March 12, 2006 Share Posted March 12, 2006 i hear that all the time. especially as you mentioned "when noise is being bounced back into the car" FWIW i think its the normal subaru boxer-4 ticking sound Link to comment Share on other sites More sharing options...
voyetra8 Posted March 12, 2006 Author Share Posted March 12, 2006 Yeah, I just read something about boxers having louder than normal valve clatter because of the design. deffred- I'll check and report back! Link to comment Share on other sites More sharing options...
wukilla98 Posted March 12, 2006 Share Posted March 12, 2006 Is the noise always there, or does it come and go? I had my car serviced two weeks ago for an issue w/ the the timing belt guide...noise was gone for a week then it came back, (noise comes and goes at will) I will try and scan the service receipt at work next week....

derffred Posted March 12, 2006 Share Posted March 12, 2006 it may be something stupid like a rock stuck in the tire tread, or it could be something like a faulty wheel bearing? just because it's from the front of the car and is speed dependant, doesn't mean it's the engine.. just trying to get all the info.. let us know!

LzyKid4Life Posted March 12, 2006 Share Posted March 12, 2006 I believe I have that to...My personal opinion would be its "normal" for a subaru...I had a 95 Impreza for 10 years and always heard that sound.. same with my legacy... Link to comment Share on other sites More sharing options...
BOXRPWR Posted March 12, 2006 Share Posted March 12, 2006 might just be your fuel injectors....they make an audible ticking sound. I know that mine tick pretty damned loud. but they are PE850cc size. Link to comment Share on other sites More sharing options...
skiphast Posted March 12, 2006 Share Posted March 12, 2006 It sounds like you are hearing wastegate flutter. It usually occurs at lower RPMs, but can be heard at later RPMs on turbos with adjustable actuator arms. If it was cold outside, it would be even more pronounced. If the sound goes away off throttle, and occurs at the lower RPM's, and ESPECIALLY going uphill where the car would be boosting; you are just hearing wastegate flutter, and is totally normal.

OK, this is good to know. I just did a test with the car in neutral, and I couldn't get it to happen. It comesand goes, generally at low RPM, and my wife says she only hears it "when it's cold and I just start moving from a stop/" Yesterday I had 4 people in the car + going up a hill + low RPM, so it seems to fit the flutter description fairly well. It definitely stopped when I took my foot off the gas. Link to comment Share on other sites More sharing options...
wukilla98 Posted March 12, 2006 Share Posted March 12, 2006 ^, I would say you could hear wastegate flutter if you had an aftermarket downpipe, but w/ the stock setup, it's usually damn near silent, and most people wouldn't even know that there is a turbo lurking under hood...
