Doesnt this look pretty clean to yall? The truck has 160,000 on it and I've ran mobil 1 since 60K when I got it.....I usually change it every 5K.

I'm used to the older 350's, which is what I grew up around, and pullin the valve cover off my old 350 in high school, that thing had so much carbon buildup it was crazy! Full of it! Heres some pics...are they always this clean?

 

Wow that looks good. Clean runnin motor

 

wow looks good nick! seems clean to me. sell me ur 5.3 for my s10 blazer . might make it a iron block 5.7 or somethin .

 

Looks real clean! wonder if all LS engine run that clean

 

Looks very good!

If they're taken care of and you keep the oil changed then yes they should.

 

Looks great, someone's been keeping up with their maintenance

 

Nice, I'm glad to know that spending the extra money on Mobil 1 is payin off. I'd love to see the bearings on this thing.

My buddy is comin over tonight so I can install some HID's on his truck, hes got a 2000 silvy w/ 5.3 and I think around 130,000K. He runs conventional oil....and doesnt change it at specified intervals.....hell I made him change his fuel filter the other day and it was the original one on the truck, shouldve seen all the **** that came out of that thing, wonder it ran at all. I migh pull his valve cover for comparison. Pics later.

 

Maintenance is my pet peev.....cant wait to build up this LS1 and soak it with all the best oils lol

 

pull the drivers side for the real results !

 

LOL
