Moisture around fuel injectors

[Miguel Yoel Olivares-Garcia]

Hello everyone new to the website. I have a 06 Silverado 1500 Lt 5.3 vortec , I recently noticed some wet spots/moisture around two of my fuel injectors driver side no puddling. No CEL. I’ve replace valve cover gaskets and grommets a couple months ago. Fires up with no issues, cold start or already warm. I did notice my fuel economy started dropping. Seems like I have to fill up more often. Could it be the o rings on the injectors are bad and causing seeping of fuel? It does seem like the spots are getting bigger last time I checked (a little bit) Any suggestions will be appreciated. Thank you.

Do you smell gas?

I just had time to check. I wiped it with a napkin and no gas smell , just black looking soot/debris that has no smell. I don’t smell gas when I’m driving or in the cab.

Could just be oil residue from the repairs, Spray clean it with brake cleaner and see if it reoccurs
