jmcgaha Posted June 2, 2017 Share Posted June 2, 2017 Need help identifying this tick sound coming from the engine, it is a 2005 legacy 2.5 N/A with 193,500 miles on it. It is usually intermittent, sometimes not even noticeable, it's the loudest on startup and when I let off the gas/ first push the clutch in to shift. Not sure if it's just piston slap or rod knock or what. Any advice would help as I am new to the forum, thanks. Link to comment Share on other sites More sharing options...
RumbleRumble Posted June 2, 2017 Share Posted June 2, 2017 does it go away with the clutch pedal down in neutral? Link to comment Share on other sites More sharing options...
jmcgaha Posted June 4, 2017 Author Share Posted June 4, 2017 I can hear it when I first press the clutch in when the revs come down and the exhaust isn't loud, but if I hold the clutch in longer no it isn't audible past that first point Link to comment Share on other sites More sharing options...
DonnyJagaru Posted June 5, 2017 Share Posted June 5, 2017 How's the oil level? This is a high-miler and may be burning off more oil than in the past. FWIW I use 10W30 in mine in the spring, summer and autumn. Link to comment Share on other sites More sharing options...

Sounds like slap on cold start up. @ 194K miles no EJ is quiet you could swap to a high mileage variant oil or to a heavier weight if its that bad (Xw-40) Link to comment Share on other sites More sharing options...
RumbleRumble Posted June 11, 2017 Share Posted June 11, 2017 10w30 does nothing. 10 is the weight of the oil when it starts out cold. if you want a thicker oil you use 5w-40 unless you live in the deserts. Link to comment Share on other sites More sharing options...
jmcgaha Posted June 11, 2017 Author Share Posted June 11, 2017 Currently has 5w40 in it. I've realized the slap is much more noticeable once the engine has reached full operating temperature (when the oil would be the thinnest). When it is cold you can't hear it much at all Link to comment Share on other sites More sharing options...
RumbleRumble Posted June 11, 2017 Share Posted June 11, 2017 oil is thicker when its warm..... Link to comment Share on other sites More sharing options...
DonnyJagaru Posted June 12, 2017 Share Posted June 12, 2017 I don't think this is true. Yes, 5W40 behaves like a 40 weight oil when hot, but I don't believe it'll be thicker than 5 weight at room temperature. I've always understood it is the polymers put into the oil that stop it thinning out so much as it gets hot. These polymers have no lubricating ability so if you have the option of running a heavier base oil (like 10W or 20W) then technically it will lubricate better. But, I could be wrong.

Get a video it could be the sound of early rod knock or a false flag caused by a bad pulley or other rotating part. Link to comment Share on other sites More sharing options...
