laker

I recently posted a tread "looking at buy a 2003 2500". Thanks a million for all the feedback. The truck is a HO with the 48RE tranny 160000km. I had a more thorough look at it today and noticed some oily residue around the back of the motor under the valve cover gasket as well as a bit around the injectors. My 93 leaves an oil slick behind it but I seldom have to top it up and it runs great. Should I be concerned with this on a 2003 truck? or is it fairly common. cheers jw

I had a slight leak on my truck around the valve cover, took it in and they would not warranty it, so I pulled the plastic cover off and torqued the bolts a little more. Seems to have helped...

Lots of ozzing from the rocker box gasket the one under the valve cover.A fair amount of them replaced under warranty in the past accoriding the the posts I've read.Had mine replaced (under warranty) about 5k ago.It pays less then 1 hour to replace and retorque.

Mine leaks very small amount of seepage, no biggie, I just wash it off yearly w/ simple green.
