Wanted to give this thread an update....I needed to fix the leaking coolant from the crossover line. So I jumped into intake gaskets and whatnot also. Here it is, cold air, efans, and stock otherwise. Also removed the wide Denali engine cover. I dont like everything covered up.
This thing is filthy. Its not so much a leak as it is just weeping from all the seals just a tiny bit over a 200k mile course.
Got the intake removed in about a hour, pretty simple stuff.
A little purple power and elbow grease goes long way.
Showing my fbody roots, I decided to do a throttle body coolant bypass, I had this brass barb in the tool box so I plugged it into the line going to the throttle body. Here you can also see the valve covers which I spent about an hour cleaning.
Since these trucks are known for having rear knock sensor issues due to moisture I decided to do a new ac delco rear sensor, new Dorman harness, valve cover gaskets, intake gaskets just to kind of freshen things up. My stock sensor appeared fine.
We had some kinda crappy weather, but I caught this guy hanging out behind the shop for about half an hour.
On order from Jegs, to quiet things down some. I am gonna install it inline with the bullet muffler.
And a couple of random pics, this is a 4wd/awd transmission mount.
Front drive axles.
