Good! Might be water pump, belt idler pulley, or something driven by the belt or even other stuff in the area that can be pretty benign. The recording might help the experts who reside here.

 

I'll look again, but I think I've seen all of them. Was not able to get his technique to work for me. I'll certainly try again, the next time I drop the sump plate.

Seeing a more detailed explanation would also be helpful, for me.

 

Good points. Removing the belt for a short trial might not be a bad option. If the sound persists it will likely be an internal issue. The stethoscope should be helpful, before messing with the belt.

 

It's there and he does state that it's tricky getting up into (5 or 6) one of the two if I recall. Also, the plugs will tell you a lot.

 

Here is the audio

 

Yes - he says you need to go in through #5 to access #6. What about 1 - 4? Not even sure you can access bank #1 at all.

My plugs looked good when I had them out 2000 miles ago. The bores seemed OK, as well, as seen from the top of the pistons. I'm not losing sleep over this, but I would feel better if I had seen more of the bottom of the bores...

 

Sounds like injectors, to me. I'd double check with your stethoscope.

 

Yeah not too worrying to me. I can't get my sound bite to load but trust me...yours does not sound like mine did!

 

Sounds like normal injectors or an injector problem?

 

Hard to tell from that - unsighted - sound bite.

You (OP - sorry Strath.. ) have, or were going to get a stethoscope, correct? Let the car idle and try to get a good listen to each injector, as best you can (understanding space is limited). Do the best (subjective) comparison you can from one to the next. Also - verify first, that the noise you were concerned about truly is injector sound (i.e. don't trust everything you read on the internet).

Finally, if you have, or can gain access to the Durametric tool, you can look at data to help you determine if there might be an injector (or other possible) concern.

I'd have to go back and check my thread. There are individual cylinder 'balance' parameters that you can monitor with the Durametric. Balance in quotes because it may be under a different name (efficiency, for example). This is a more advanced step to take. Try the stethoscope check first. Personally, I think there is nothing wrong. (Again, see above - about trust).

 

I got the stethoscope, but not time to look at the car yet.
I will look at injectors and see if any sound different.

The video portion was useless, just the rear quarter panel shown.

As far as a durametric, without going to an Indy or dealer, no access. Are there other readings that can be pulled from the OBD2 port that would show a potential issue?

There is definitely a tick that was never heard before this weekend.

 

And this was right after seeing the latest F6I video on bore scoring, right?

Relax. You should be able to tell if one injector sounds different from others. Or otherwise locate the source of the new sound.

And no. There are no parameters of any value from the OBD port without a proper tool. If you don't have a check engine light, there will be no engine (emissions) related codes to collect.

 

Ha, the only one I watched was part 4 and it was after I started hearing it. I'll see what I can find out.

Wasnt sure if anything that say OBD Fusion is capable of showing would give any indications. There are many things you can monitor, but I wouldnt really know what specifically to look at or what ranges.

 

Had to look that up. If it is compatible with the communications protocol that Porsche uses, you may get useful data. Someone with more knowledge would be able to help. I would be quite surprised if that would be compatible.

 

Worry when you hear this...
