I started work on it to fix the intake manifold leak and replace the valve cover gaskets. If you look up the billable hours to remove the intake manifold it is right around 2 hours. As I'm finding out, that's 10 minutes to remove the the intake snorkel, unplug the IAC, MAP, and TPS, disconnect fuel lines and unbolt the EGR plumbing. 30 minutes to wrestle with the spring clip for the PCV elbow that Ford decided to install facing downward so the tabs on the spring clip almost inaccessible. And the rest two hours, and then some, is spent trying to remove the five xmas tree clips Ford uses to secure the wiring harness to the intake manifold when they could have attached it to the firewall. I broke one, pulled another one out from under the tape, and I still have one to remove before I can remove the intake manifold. There really are better clips for securing harnesses. I don't know why Ford has continued to use these for decades.
Also, rubber elbow it was holding on crumbled due to age. And now I can't find that elbow online that the heat deteriorated. I swear I saw a post wherein someone replaced it, but I can't find the post.
