991.1 GT3, ~30k mi, unknown mileage on G6 Engine.

On an onramp today, WOT in 2nd gear, uphill, manual mode.

Lost traction for a split second. Revs spiked from 7500ish -> limiter. Fuel cut like I was shifting, back to 7500ish all in the blink of an eye.

Now I have what sounds like a valve pinging. No question metal on metal sound. No CEL or anything.

> panic ensues. Merry Christmas to meeeeeeeeee.

 

Keep running it hard… when the engine goes it will be loud and very noticeable. Also it’s still under warranty !

 

Punch it Punch it

 

Not your problem…. Yet. Keep the foot down

 

Do you hear the sound at idle or only while driving? If the latter maybe something mechanical outside the engine?

your dealer should be able to give you the mileage when the g6 was installed.

 

This. Does it follow the revs? Does it follow your speed? Is it constant and consistent?

 

Follows revs. Louder with more load. Hoping that this is just a header leak or something, as this is a replacement engine already.

Dropped it off, waiting on Porsche to get back to me. We'll see.

 

Passenger exhaust baffle blown out. Looks like I'm 2 months late for a Dundon sale....

 

Whew! Glad it wasn’t major!

 

Sounds like it's time for a side muffler by-pass!

 

^^^ this, best exhaust mod for the $

 

If it was me, I would get to a friendly indy shop (no carfax reporting) and get an overrev report. If you have a good scanner you do it yourself.
