It’s a different car, but similar ticking once warm. My 996 Turbo has a tick like this. Oil cold (not water related in this car) there is no tick. once the oil is warm you hear a ticking. Changes with RPM, and at a certain point it seems to go away (hard to tell as above 3,000 RPOM there’s a lot of other noise coming up that may mask it). Back in the day Porsche replaced come 996 Turbo and GT3 engine over it (same basic engine). Some people did complete engine rebuilds and had the same noise after. NO one came to a good and well known conclusion. My mechanic, who worked at Porsche’s factory and as dealers here, believe it’s just the wrist pins on the pistons. Occasionally some of them made noise. No real fix, and even when rebuilding a non-ticking engine back in the day, he said you occasionally got a noisy one and the engine ticked after the rebuild when it did not before. Mine has ticked for the 10 years I have owned it. oil analysis shows nothing but a very healthy engine. I even tried thicker oil once. Maxed it stay quiet a little longer on warm up….but once the oil was warm it made noise.

YMMV, just. Just a thought. My 3.2 and 3.6 don't tick. The 3.6 had a similar but different tick, and reapplying my injectors fixed it (I replaced them because one was leaky, not the noise).
