Ticking from engine more noticeable with top up and seems like from behind driver's

Whatever it is, if you've developed a noise I would have it checked immediately. Check your oil level as that is fast and easy.

Oil level is fine. Bringing it to a shop today to have it checked out

Looks like it is an injector, but not to the point where it needs to be addressed. one is just louder for whatever reason...maybe down the road it will need to be addressed. The mechanic definitely could've tried to sell me something, but he was very honest and straightforward...will definitely use them again

Thats great news. I added a injector cleaner to my tank yesterday and viola:ah: (not violin) the noise went away in about 10 minutes. Mine was ever so slight of a noise.

[dennis]

Mine is slight as well. And i only noticed it recently since I have been driving with the top up. What type of injector cleaner did you use? my past experience is Techron is the best

I have been using B 12 cleaner and no more tick, CEL (on and off) and the rear bumper is cleaner after a long drive.

I used the Techron

Another way to clean your injectors is to have them pressure cleaned by your favourite car repair shop. This basically means that they run your engine on pure TechRon for an hour or so. This cleans out the gunk from the injector solenoids. Make really, really sure that they change your oil after this procedure. A lot of the solvent ends up in the oil and it also eats rubber in this high concentration.

This was the product of choice in a past Porsche bulletin I had, I think it might go all the way back to the 944 days.
