All right I've learned alot and fixed a lot by reading on this forum. So thanks everyone for the insight and help along the way. Currently, i'm about to attempt the cam cover replacement on my 175,000 mile rig. She is leaking oil pretty good in the back (Only when running). Dealer wanted $3k for labor alone on this. I already purchased the part. Was wondering if anyone had any insight on doing this replacement. There isn't much online about doing it that I've found. Please share link if you see a good video out there. Wish me luck.
