1984 Valve Covers
Just a quick question for those that have experience with 84 valve covers.
I am doing a water pump, I had to loosen the AC compressor, In order to get one bolt out from the back of the AC compressor I had to remove the valve cover.
My question is, Do I need to put the valve cover back on prior to reinstalling the AC compressor?
right now, I have that long rear bolt back in...but as it got late I decided to stop. Now, I am wondering should I wait for the new Valve cover gaskets or go ahead and button up a few things while Kragen gets the Gaskets.

So......does this mean you can put the Valve Cover on after you get the AC compressor installed?!?!?!?!

I glue the gaskets to the valve covers so they don't slip out of place while I get the covers situated. I put a bead of the "Right Stuff" on the thoroughly degreased valve cover gasket surface and then, time permitting, put a weight on the valve covers for overnight. Then, just before I am ready to put the vc in place, I use lacquer thinner or acetone to remove all traces of oil from the gasket surface of the head.
Now that it's too late. I should mention that I don't think you had to mess with that rear facing bolt or remove the valve cover to replace the water pump. If memory serves me, once you get the brace from the top of the compressor removed from the intake manifold and the the other brace removed from the exhaust manifold stud, the only thing holding the compressor, with bracket, to the engine is the two water pump studs. Once you get the nuts off of the two right side water pump studs, the bracket, with compressor slides forward and out of the way. If I remember correctly.
RACE ON!!!

well........a bit late but thanks.
you said two things
A) Yes I used a small amount of Blue RTV between the VCG and VC. I let it sit until it got tacky, but fearing that it would dry with a Void, I put it on. The VCG held tight like you suggested.
B) That Bolt wouldn't wriggle free. and Yes I had both of those bolts down on the water pump loose. I couldn't get the whole assembly to move up high enough for the bolt to fit in that channel between the VC and intake. Plus I was scratching the crap out of the VC trying to do this. The Two fuel lines that run up through that mounting bracket were thwarting my every move as well.
Took off the VC and got the bolt out, then the Mounting bracket nearly fell out on its own......isn't that the way it always happens??
CFI, sincere thank you for your hand in this.
I got it all buttoned up and took it for a test run already. No leaks and it stayed between 185-193 for the short run around the block.
I changed out the thermostat to a 180°F because on cool days the OD would drop out due the temps dropping below 160°F while on the freeway.
New Water Pump, new Smog Pump, new thermostat, new Valve Cover gaskets, flushed radiator, New Hoses,
They bury that damn Water Pump....it is not easy swapping that one.
