Now, the question - there is supposed to be a 7 (?) digit engine ID stamped on the engine (somewhere near the cylinder head) - can anyone give me some clues as to where this last ID is located?? Right now I believe it is on the driver's side (firewall side, of course) near the cylinder head - worst place in the world as far as access......I'm sure some of y'all have been down this road before. The real kicker (and reason) for this egg hunt is that the oil dipstick that came w/ the truck is the wrong one, so I need to rectify this situation if I'm ever going to be able to determine the true level of oil in the beast!!! Thanks in advance for your time!!!! Magruber

I still think it is holding pretty well with none of the classic symptums but I got the check engine for the O2 and don't see the point in changing that or the CAT until I get the plenum done.

I have been reading up but may be looking for some crunch time crisis advice this weekend since it is my DD.
