Need expert help. ENGINE NOISE. (Audio clip attached)
Hello, I hear a stranger noise in the engine of my 986 when accelerate, and when slow down, too. Here the direct link to the audio clip:

The link says that you can only listen to it ten times then it's deleted. I'd love to hear it if there's some other link to use like YouTube.

Have you noticed any change in power? Have you replaced your air filter lately? if it's clogged really bad then it could be trying to suck in air throught the intake somewhere else(where it shouldn't) If not it could be too much crankcase pressure blowing it out the vent tube Could be the dreaded IMS bearing has gone bad Keep looking |
I haven't notices any power loss and the air filter is in good condition.
The IMS works perfectly, because I've changed it. I hear the noise before and after I changed the IMS bearing. Where is located the air ventil? Do you think it may be the chain tensioner? |

Anyone has the same noise?
I'll check the breathertubes, but if they're ok, probalbly I'll replace the chain tensioner, but they 3 are so expensive to replace if are ok. |
