Tick sound engine off

[YoYo_4G63]

So after i turn off the engine or simply turn it at the damper with a wrench, i have a weird tick noise coming from the head Engine is new, gsc s2 cams, gsc springs and revised lifters. The engine doesn't makes the typical tick noise while running.

My 1g 6bolt also makes a loud click noise from the upper head area, for a few minutes after I shut it down. I am also interested in what the noise is.

How long has this been happening?

How long has this been happening?

since i did the engine, it have like 30hrs of use. The other engine/setup had almost the same parts except for the 3g lifters and cams and didn't make that anoying sound.

Are you sure that it's not lifter tick? Did you check the oil level? What kind of oil are you running? A quick vid could probably bring more answers.

I bet it is the sound of metal contracting since it is now cooling off. A lot of cars do this, it's normal for it to happen.

Sounds like a case of tappet noise, which is common on hydraulic lifter motors when they lose their lift due to lack of oil pressure - a bit of clatter until pressure is built back up when starting.

Course, you've got a modified head with larger cams and larger opening 3G lifters that demands more oil to function, thus I would begin to get used to it.

My car has been doing this for as long as i remember. A few minutes after it shuts down at temp it makes a few audible clucking noises. I assumed it was something with the hydraulic lash adjusters cooling.
