Default cold engine start clicking noise, what is it?

I replaced my fuel filter on my 2003 2.4L toyota tacoma 2wd. 65k miles. At the same time I checked the valves. No valve adjustment needed. Then i started hearing 4 to 6 rapid metallic clicks from the engine compartment when I start the engine cold. Clicking lasts 1 to 2 seconds. Sometimes happens when engine warm. This fuel filter is not original equipment.

ideas?

tks,
pa

Surely it isnt the injectors making the noise?

Can you try to isolate the noise one morning? Have someone else start the truck with the hood popped so you can look and listen.

Relays can fail!

I would pop the hood and take the cover off the relay compartment and have another person listen closely. If you think you have it narrowed down, swap that relay for the horn relay (or any other non-critical relay that is off in resting position). If you don't hear the noise anymore after a couple days, you can be pretty confident that was the issue, and replace the relay with a new one.

This trick is also how I've always tested fuel pump relays - swap them for the horn relay, check if the horn works. If the horn no longer works, you've found your issue. Super easy.

This could just be oil not to the lifters yet. The Toyota 1.8 engines do a lot more than just tick on start up after an oil change.

Once the oil is warm it moves through the block quicker so no ticking.

Yeah but it would do it for more than a second or two if it were lifters.

Not saying it's a bad lifter, just that the oil is not getting to the lifters soon enough.
