TB removal and then some!!! - Page 10 - ZR-1 Net Registry Forums

Roadster · 05-15-2017

Doing double duty today, working on the heater box on the 74 and the TB for the ZR-1. Thought I had paint stripper out at the 74 as Phil suggested, but not so....also am having a hard time removing the TB cover. It feels like it is cemented in.....lol I don't think its been apart in 23 years....lol

in the following pics, you can see the buildup after all these years, really needs a good cleaning. I know I am going against some of the info posted on TB's from members about leaving blade surfaces untouched, etc. And then some members suggest a good cleaning. I am going with a good cleaning and I have already removed most of the "dag". My reasoning is that if this was a replacement NOS unit, it might not have the "dag" on it.
So its like starting from scratch. I might be right, or I might be wrong. Will have to wait and see how everything turns out!!!
check out the throttle shaft and the dirt on it....

rear of the TB...

more dirt and you can notice the wear mark on the actuator cam follower. it's only a slight wear, so I think it can be smoothed out nicely...

Carter did and always does an outstanding job....thank you sir!!!

Now if I can only get my old cover off my TB.....

Glad you like it. Was fun trying to fit what you needed in the space provided. I like it and glad you do to👍

Just posted the following on my Poll thread. Reposting here for anyone interested....

Just received a NOS EVAP connector assembly today. As you will notice in the pics, there is a black plastic tie around the connector. And the plastic "lines" fit in the connector very tight. There is even one spot where the "tube" seems to be dented, maybe from when the installer was inserting the tube into the connector...JMO
So IMO this seems to confirm that there was a plastic tie installed from MM when the engine was assembled. Again, JMO.....FWIW...

FYI if interested, the spark plug wires on the RS of the engine,
#2 #4 #6 and #8 plugs wires have the one large 4 slot wire separator attached at the rear of the engine. Then there are supposed to be 3 more additional wire separators, one with 4 slots to hold all the wires and 2 more with 3 slots before the wires go onto the plugs. On my RS, I am missing 2 of the 3 slot wire separators. I don't know if these are even available anymore...
Also the large separator on the rear of the engine should have the wires in the following order. Top #2, then #4, then #6 and then #8 on the bottom. There is also conduit on #6 and #8 plug wires in that area. Then the 4 slot separator that is next in line should have #2 on the right top, #4 on the left top, #6 on the right bottom and #8 on the left bottom.
I know I have a lot of time on my hands.....lol

Also #8 plug wire is now replaced...

the rear wire separator...

the next 4 slot wire connector...

LS plug wires #1 #3 #5 and #7 are routed the same as the RS with the same separators. I am also missing 2 of the 3 wire slot separators on this side...
Large rear 4 slot separator....Top #1, then #3, then #5, and #7. #5 & #7 should both have the conduit on them, but my #5 is missing that conduit. Easily replaced.
The next 4 slot separated again is similar to the RS, with #1 top left, #3 top right, #5 lower left and #7 lower right.
For someone replacing or wanting to get their wires in the correct orientation, this is the result of my research....FWIW....

This is what happens when your retired....lol you start thinking!!!!
Prepped and painted one of the water outlet pipes with the paint that has been suggested by Cliff. Not sure if that is the shade I would like to have, although it is growing on me.
Compared it with the air horn that I repainted recently with the "correct" shade of paint from Jerrys. And yes you can see a difference. Since we'll be away for a few days, it will give me time to think about which way to go!!!
Overall I am very happy with how the one pipe turned out. I may even experiment and put a coat of Jerrys paint over Cliffs and see what I come out with. Decisions, decisions, decisions.....lol

my open unscientific paint booth...

very light coats...good results...

the difference between the two pipes....painted and untouched factory...

difference between the painted pipe and the recently painted air horn...

Roadster · 05-19-2017

Back into the booth again, this time with the RS outlet pipe. The more I look at this shade, the more I like it...the plenum may get this shade after all and then change the color of the air horn.......

in the booth...

topside...

finished part...

The lighter color looks quite nice. It'd probably make the LT5 "pop" a bit more than the oem color.
