JG, I don't have a membership to post.
Cable comes from tower to a 90degree pulley and attaches to ( a horizontal assembly) a spring anchor, spring, spring anchor through a skeleton spring housing with a tightening nut on the anchor. 

I ordered some gas struts to see if I can get them to assist the spring. Not sure exactly how I will try it, but I will. I am still attempting to contact a spring manufacturer.

Yeah, seeing lots of this and people that had no clue this was happening.

I chase the threads about every 5 years and use a round 3/8" brass brush annually. I got my replacement knock sensor from Summit Racing. I do not tighten the plug or sensor much at all, perhaps hand tight, plus a 1/4 turn, then check for leaks. The water pressure down there never exceeds 7 PSI. I threaded a 0-15 PSI gauge (with max hold) into the drain plug to verify this. It's some of the silly things retired instrument techs do.

I also vacuum out the drain holes at seasons end to get any residual crud and water out of the block. Easily get an additional quart of water out and a bit of crud.

The coolant tank has a High and low mark on the side. At a cold engine, should it be between the marks or is that at hot temp?
