Yeah so I finally got the freaking thing unbolted, and me not sleeping I didn't think for the longest time that I don't have to get the serpentine belt off over the lip on the ac pump, i just need to slip it off the self tensioner I'm dumb

Anyhow, I got 2 questions, first off how do I know when I have completely drained the a/c of the R-12? Secondly, I had to make a slight dimple in the valve cover for a bolt to clear (and frustration too) anyhow, this engine is the fuel inject TBI with the ribbed valve covers and the dimple simply removed 2 of the ribbes and pushed it down half of one. It is right on the end so I don't think the rocker will hit, I even unplugged the primary and turned it over to see, but there was no loud sound. Instead a slight ticking, and since this is not my vehical I'm not sure if this sound is common or not? So I guess my second question is how much clearence is there from the stock rockers to the stock vavle cover and is my dimple safe?

To sum it up:
1. How do I know when I have drained the a/c's R-12 completely, and also how would you recommend doing it (I simply used something long and with my sleeve over my hand held the filler valve open, some crap squrited out so I left it a while then now I can get the ocassional hiss to come out, but I don't wanna pull that hose off until I am sure)
2. how much clearence is there from the stock rockers to the stock vavle cover and is my dimple safe?

Thanks alot guys

 

if the dent is too big, it will hit the rocker arm.


simple, and loud, so you will know.
