Well, I wanted to change the temp sending unit in the lower intake today. Put one layer of teflon tape on the sensonr with a tiny amount of RTV up top. Just snugged it up and the damn thing cracked my lower intake and when the car is running it pisses coolant everywhere! Now I had to overnight a used manifold so I can get her running by Friday to drive it to the shop to start all my suspension installs and get her scheduled for paint. What a PITA it is to get all the shit off on a 5.0 to get that lower manifold off. SOOOOOOOOOOOO Much easier on a 4.6 lol
