jackal8788 Posted April 26, 2016 Share Posted April 26, 2016 Has anyone else experienced a mild 'burbling' sound in this area? I seem to notice it most at idle, probably because normal exhaust and road noise drown it out at any other speeds. It doesn't seem to be affecting performance but it is a little weird as though something were loose or rattling slightly.

BBPeik Posted April 26, 2016 Share Posted April 26, 2016 I have not heard anything like this. Any chance you are just hearing something from the exhaust now that you have the metal skid plate? My someday I will be done with it thread. Link to comment Share on other sites More sharing options...

Any chance you are just hearing something from the exhaust now that you have the metal skid plate? I'm not sure. I need to do a little more investigation to see if either the skid plate or the new header might somehow be causing it since I don't recall the noise before and those are the only things that have changed recently. I might try to get a recording of it too if the sound can be clearly heard. It's probably nothing but given my recent issues in the timing belt area, I'm probably hyper-sensitive.

ChrisCrash Posted April 26, 2016 Share Posted April 26, 2016 On the left side of the engine towards the front? Ive heard this myself and pretty perplexed by it. I really have to put my head into the engine bay and it sort of sounds like false detonation to me but no knocks monitored. I also have the jug out of the intake so I thought maybe its the air just bouncing around in the box. Link to comment Share on other sites More sharing options...
BBPeik Posted April 26, 2016 Share Posted April 26, 2016 Understandable. On interference motors anything up with the timing belt is scary. My someday I will be done with it thread. Link to comment Share on other sites More sharing options...

Might pull the belt cover off and see if everything looks to be doing what it should. VF54 to 20G to VF54 to 18G build thread Link to comment Share on other sites More sharing options...
NVAKeith Posted April 26, 2016 Share Posted April 26, 2016 Haven't hear it on my Subarus but other cars make some funky sounds when the water pump is on its way out. Link to comment Share on other sites More sharing options...

That's interesting...it could make sense though because the new timing belt and tensioner are going to be putting more load on the bearings. Crap.....
