220,000 miles, engine light is on and I've been told by few friends that it's likley the Oxygen Sensor, I've read several posts and notices that there may be more then one sensor. #1 Where can I find detailed instructions with diagrams hopefully, how to place one or more of these sensors, if I'm able to determine through the local parts store which on it is? #2 Is this a job that a basic do it yourself person can do? Thank you

I was given a 2001 chevy silverado 2500 6.0l vortec. Its has 297,500 miles on it and runs very good, but however i have this tapping noise like everyone else have. But in my case, its at the start, during, and finish of my trip driving. My question is, "Will a 20/50 oil help or what would someone with experience suggest?" Thank-you in advance for any help. Kevin

| On the Chevy Silv., 2001 - 6.0l vortec, w/ 298k miles...the oil pressure gauge is bouncing back and forth between 30 and 60 while i drive and it will literally go to zero (0) if i stay in idle/park and the message light will say check oil pressure and the truck will cut off. Think the oil pump is bad; going bad; the lifter/s or valve/s is tapping sorta loud? Thanks in advance for any advice. Kevin | |

I have a 6.2 Flex fuel 09 403HP. My question is does anyone know how the roller lifters are oiled in my engine? In the old days of hydraulic and solid lifters splash seemed to work in non Hi-Perf. motors. I have read on some forums that roller lifters and roller rockers need lube. It is said,in low rpm range, MODERN ENGINES do not splash as much oil as older motors and the needle bearings of modern motors need oiling at low RPM's (2000 to 3000RPMs) or might have wear and breakage issues. Does any one in this community know of or heard any or some or just a few 6.2 L 403 HP V8's having roller issues? Does anyone know specificly,does the 6.2 have mist,pressure or non needle bearing rollers? I run syn. oil and will be running Oil analysis so I assume I would know if the needle bearing are wearing it would show even though I am running a bypass system that has a 2 micron absolute filtering. Ideas and opinions would be appreciated. |
