After getting the knock sensors in, I tried to make a resource for anyone who may have gone too fast and just threw everything together but didn’t pay attention to how they did it.  This video is just an overview of stuff and where it goes.  There is another video later in the series where I visit the concept of, “where stuff goes”, to finish off the engine build.

I learned a trick from someone along the way about using a (preferably new) toilet bowl brush and some carb cleaner to clean out the intake manifold while it’s still outside the truck.  I did do that and then used another smaller brush for the intake runners.  I will be installing a catch can later, so I wanted to base line the intake as clean as possible.

Later in the video, I get to the installation of the intake manifold.  It’s not hard, I chose do it when all the lines were off to the side thinking I would reduce the effort necessary to get it in.  It wasn’t hard at all.

Next on went the power steering / alternator bracket.  Take care to make sure all the hoses are where they belong so that it does not present a problem for you later.

Valley Cover Removal | Knock Sensor Analysis & Why Not to Powerwash – vid 17

Removing the valley cover is pretty straightforward.  However you need to pinch the connectors on the knock sensors pretty hard to get them out.  Then, the knock sensors come out using a 22mm socket.  Then the easy top bolts and the thing comes right off.

Things I learned:  I read somewhere to power wash your engine before taking on a task like this.  So I did (about a week prior to starting).  A few days later I got a check engine light (don’t remember the code, but it was the knock sensor).  I did some more reading and discovered that power washing the engine can get water in the knock sensor and throw a code.  So, when I pulled that knock sensor out and saw what bad shape it was in, I was not surprised.

Another learning experience:  Much earlier, when I pulled the heads, I was planning a cam swap.  I was not planning on pulling the motor at that point.  By the time I filmed this video,  I find myself wanting to pull the motor and I don’t have heads on it as a convenient attach point.  I purchased the lift plate you see in the video, and I am glad I did.  It made pulling the engine a cinch.
