While changing oil this yesterday, noticed that there appears to be a "crack" in the front of the valve cover. Did not see any evidence of oil coming out but this may be just a matter of time. Murphy's law comes to mind right now. It will leak at the most inconvenient time and place! Has anyone come across this? This may be a good time to buy that new red (black?) Cummins valve cover also. Where is a good place to get this new cover? Any one know of the stock numbers for these two? How difficult is this changeout? Just to be sure, will also get a new gasket when I change this one out. Have a 98. 5 with the 24V and the back side nearest the firewall will be a pain for access. Will also look in the service manual but with all of the experience on this site someone hopefully has some goood hints on making this job go smooth!
