Fixed the annoying "tick" sound today that plagues these cars and the 996's.
There was a hairline crack in the weld of the header where it is joined to the manifold, both sides at the first tube. You could see a slight black sooty line where it was leaking.
Removed headers, grinded out and welded it back up. Flat and square, good for another 20 years.
Nice and quiet like it should be.
It's the little things, really. lol
