Work on the world's most labor intensive tune-up continues. Saturday, after breakfast, Sean and I went to the storage to move the project forward. Not too long later, Dad showed up to hang out which was cool. Sean mostly cleaned parts for me as I pulled it apart. I pulled the air pump and then the air pump bracket. Then I could finally pull the water pump (one of the bolts is a stud and it is shrouded by the air pump bracket). I had a ticking time bomb on my hands. The water pump was obviously leaking and the bearing was obviously out....

I didn't lift the bearing seal. The pump came off exactly like that. I can't believe it wasn't making a puddle of coolant on the ground. I also can't believe it wasn't noisy. I was catching a faint smell of coolant but that was the only indication I had. Man am I glad I didn't mush this thing to San Angelo. I wanted to bad but with only having an expired Florida plate and not knowing the car that well, I decided to take the truck instead.
Next, we pulled the belt, the tensioner and the balancer. Finally, we could get to the Opti-Spark! Next I scraped a lot of crud off the front of the engine, mostly above the Opti-Spark in the interest of keeping it out of the Opti-Spark. Here's what it was looking like by then....

Note the obvious evidence of the water pump leaking directly onto the Opti-Spark. No bueno. Next, I got the distributor cap off, thanks to MSD including a tool in their cap and rotor kit for the E4 torx screws. I didn't have a deep E4 socket at the storage and was ignorant of the need for one on this job. I have one now! Here's a look with the cap off.....

That's where I ended up stopping. I didn't have a T9 torx screwdriver at the storage to remove the distributor rotor and was ignorant of the need for one on this job. I have one now! I believe the cap and rotor to be the original units. They have a lot of wear on them. Here is a close up of the rotor....

And here is a close-up of one of the terminals inside the cap....

I was surprised to see how dry the inside of the cap looked. I'm looking forward to seeing what the Opti-Spark looks like behind the shield that's under the rotor. I'm not looking forward to the plug wire replacement since I'm going to be a stickler for putting them back exactly as original. I'm not crazy about this LT1 architecture at this point but this project should put a ton of life back in this car. I'm surprised how well it ran, considering. I'm excited to see how well it runs when the work is done.
That's it for now friends. Hopefully I'll have a good update after next weekend. Thanks for following along. Until then....
Best,
