Coolant Pipe by-pass connections
I never did connect the coolant by-pass line from the throttle body or directly
from the intake manifold to the radiator. It never created any problems
for me but it should be connected to prevent potential air pocket build-up and
cooling problems so I took a few minutes to devise a proper connection to the
- There was an existing plastic fitting on my IROC aluminum radiator that
was threaded with a 12MM x 2.0 plastic O-ringed plug near the top of the
radiator on the passenger side. I found a 12MM x 2.0 x 10MM long
stubby bolt (used the O-ring for a good seal) and used this to fabricate a
fitting that enable me to connect a 5/16" hose.
- On the first design that I tried, I drilled a hole through the center of
the bolt using a 9/32" drill bit and then tapped it with a 1/8"
NPT pipe thread tap. I then screwed in a straight
brass nipple with a 1/4" barbed end into the bolt. I didn't
like the fitment of the hose once installed because it aimed it too far
- My 2nd attempt involved finding a brass
nipple with a 90° bend to it and screwing this into the bolt.
Whola! Correct angle that I was looking for and more importantly looks
better since it aims the hose in the direction that it needs to go.
- This final view shows the
completed installed hose at the radiator with the OEM protective sleeve
installed over it and an OEM hanger that I found and used to secure the hose
to the radiator.
With Phase I now basically complete I started the installation of the
following components: MTI
"B1" camshaft & kit - 222°/222°, 0.559"/0.559" @
114° C/L; LS6 intake manifold and ASP crank pulley.
- The installation was pretty straight forward. I replaced all of the
valve springs with new ones contained in the cam kit along with new hardened
pushrods. The only real pain here was breaking an 8MM socket while
attempting to loosen and tighten the rocker arm bolts. I finally
settled on using a thickened impact quality 3/8" drive socket since I
broke a high quality S&K chromed one.
- Final buttoning up was going along just fine until I tried to replace the
crankshaft seal on the timing chain cover. To make a long story short,
after trying to carefully install the seal I
managed to break the aluminum seal retainer (the LS1 timing chain cover
is a cast aluminum unit!). I had to order another cover and it will be
here by mid week next week so no more updates until them!
