Exhausted

Anyone check on this? I was going to check the front left O2 sensor

My 5.3 has this same sound

"Oil Pump The oil pump design on these engines is a two-speed vane-type pump. Its dual-pressure control enables operation at a very efficient oil pressure at lower rpm, and then delivers higher pressure at higher engine speeds. At temperatures of 32°F (0°C) or colder, when the engine has been sitting for a few hours, it is possible to have air enter the pump through normal oil drainback. Upon start-up, a short rasp sound may be heard from the front of the engine. It is most often heard during a remote start. This is a normal condition." Below 32* is BS It was 72 when I left work and the truck sat for about 9 hours and still made the rattle noise upon startup

So I listed to the video and thought I heard it but is yours making the "rattle"/"grind" noise on cold start after the truck has sat for awhile? It only lasts for a second or so but does not sound good.They're saying it's the oil pump?

I would like to see more pics of this one!!

Yeah I'm running 55w ballast, I'll be switching to Morimoto's 35w kit
