High Pressure Crossover - no change
I thought I had a cackle, and what sounded like an injector clicking. Installed the HPX today, and nothing changed. Maybe it wasn't cackle, and maybe it was a lifter. It quiets down after warmup. Maybe there will be some longer term benefits. I used the solid stainless line, so I don't expect leak problems.

Possibly poor oil flow through the HPX line until the oil warms up enough to freely flow through it. Are you using 15W-40 or 5W-40? and how cold is it right now where you live. If you're using the 15W-40 and it's cold, oil's probably not flowing very freely through the HPX line.

Why would the HPX have any bearing on a loud injector or cackle. There shouldn't much flow through the HPX, it's just a balance tube that allows the ICP sensor to "see" the rail pressure in both heads.

the HPX wont cure cackle and injector knock. well, maybe some injector knock, it is quieting the injector some by equalizing pressure between the oil galleys. it is designed to quiet overall engine noise and make a smoother tone. i notice faster startups too.
EDIT- server was busy, and i tried to reply at 9:29, and it was "too busy" so i came back at 10 and i forgot i still had this reply. sorry it was basically what Scott said.

In addition to what u folks have stated my impression of one of the attributes of a HPxline is a sort of shock absorber for the HPOP system. i get this from the two comparison graphs at the ITP website.

I understand.... mine smoothed out some also, you just used terms that I don't typically associate with the HPX. Cackle and idle knock are fuel issues.
