Ticking motor please help

[Kreep306]

So I came across a 99 Cobra with a tick I thought it was a lifter issue, but I have replace all the passenger side (16) the tick is still there. If I disconnect the injector the noise goes away someone suggested that it might be the wrist pin that is causing the noise that you can hear from 800 to about 2500 rpms. Any other options or recommendations?

Which cylinder is ticking? Have you cut open the oil filter and inspected the filter media for metal filings/bearing material? Can you post a video so that we can hear the sound?

The cylinder making the noise is the one under the throttle body

Since unplugging the injector silences the noise, I'd lean toward a wrist pin in that cylinder as well. I'd still suggest opening the oil filter to see what you find. You've done the usual tests like remove the belt and start the engine to verify it isn't anything in the FEAD, check for exhaust leaks, etc. correct?

Yea done all that already I've changed the oil 3x in 2 weeks since I got the car should I still search for metal shavings?

It's worth having a look in the filter media before you start disassembling the engine.
