not my car or video but i have a friends evo that sounds identical to this tapping and not quite sure what it may be, he does have upgraded lifters in the car. any educated opinions are greatly appreciated

 

Could be injectors,mine click like that.

 

^ Those would be some loud injectors...

Could also be a sticky lifter or a stubborn rocker arm smacking something it shouldnt..

 

Lash adjusters

 

How do you go about "lashing" hydraulic lifters?

You misinterpreted what he said.
A lash adjuster is the same thing as a hydraulic lifter,
A hydraulic valve lifter, also known as a hydraulic tappet or a hydraulic lash adjuster.
Sounds to me to be a Lifter.

 

I see. Thats for the clarification guys

 

I sometimes forget different meanings across the pond

 

even with having upgraded lifters you guys still think it could still be that?

 

bump

 

I had the exact same noise on my 2.4....turned my timing belt was off. I adjusted it to tdc and noise was gone...sounds like piston slap which had me worried

 

I gonna say injectors- injectors sound exactly like that but less pronounced as in this video, get the injectors flow tested. Get a long flat head screw driver, while car is running, gently place the flat head on the injector you should hear a rapid and faint close open sequence of the injectors. There is a how to on this forum. I'm thinking your buddies injectors need cleaning. GL

 

The injectors are basically new, I can hear the injectors making the normal clicking but this click is different sounds more metallic tapping

 

What aftermarket or upgraded lifters are they? GSC ? Some are required to be "bled", while some do not. If that turns out to be your injectors, those are some loud injectors
