Wow. That was exciting....
It was so exciting... especially when I realized that GM expects me to remove the AC Compressor so I can remove the last support strut... Oh, and removing the battery so I can reach the last bolt at the way back...
I lost one 10mm deepwell socket... it was sentimental to me... it fell down into the firewall somewhere... never to be seen again. damnit
All in all, the task took about 4 hours, but I didn't kill myself. Wednesday afterwork, I jacked up the car, then removed the tires and the brakes (hoped to turn the rotors, but one is gnarly, so I ordered new from NAPA). Thursday morn, I removed the left cat (chasing the leak, I wanted to be sure the cat was ok, it was) and took the engine apart. I was able to swap out the gasket and button up the engine compartment on Thursday, that left putting the brakes back together (waiting on rotors, should be in this AM).
Not a bad project... just requires taking everything apart!
I will do some photo documenting and share it as a C4 Guru tech tip early next year!
And you are right, the PS isn't that bad... but on the later LT1s, the manifold is obscured by the AC compressor, the ASR module and all the plumbing for the AIR system. It's really tight in there.

I've learned that these things called "wobble extensions" sometimes make life a little easier. Oh, and Gearwrenches. Wish I had known about those things when I changed plugs (and everything else) the first time....

I might still find it... I will go looking tomorrow.
What they really don't want you to know is that they build the entire car around the heater core.






Here's another thought for you'all............. Reverse-engineering! I'll explain.
Engineering departments that have been in the business forever... They reached a point where (they've been at this point for many years now) can engineer past the current problem, and engineer-it for failure at some point-in-time in the future.

Ever stop and think about how much $$$ is made at the dealers parts counter??? Mind-boggling isn't it?
I know,,,,,,,


That was absolutely unpleasant to say the least.

. And I am not about to pay big $$$ to have it done at a shop..
I think the trick is to keep the coolant fresh.
I changed the heater core in a friends' moms 1981 Escort. It took all of 20 minutes.
