LS 2 is common for the SD cars in 73 on the rad support. I think the valve under the engine may be some Calif. emissions type thing, Nice car.

Interesting valve that I have never seen, is there a GM type casting on it?

I will go take it off and get a better look.. Since the Pontiac guys don't know, I wonder if it is the remains of one of those quick oil drain things....

That looked fuel line related, and for it to mount on the timing cover like that with the angle it makes me wonder. Not too many aftermarket companies would engineer that funny angle.

I took it off and cleaned it. It is not a oil change thingy. The large cup section has a freeze type plug in it Here are better pics.

Charley, that is a reverse modulator for the vacuum assisted muffler bearing, only installed on Washington cars due to some new law about keeping the state green, want to sell the pos???
