I'm doing plugs, wires, and cap on my '88. The distributor cap had a hose attached to the top of it. When I went to take it off, the whole hose came off in my hand with a bit of whatever it was attached to stuck in the other end. Where did the other end go, and is it important?

Where does this hose go?

 

I think thats the vent hose you should have a lawnmower fuel filter on the end somewhere.

 

This shows the vent system

Thanks, I've never seen that before. What's the idea of venting the distributor?

 

Basically it was a recall we did 'back-in-the-day' to keep the V12 from burning to the ground!!


ETA
It was ONE OF THE RECALLS.

 

Fumes and ozone (caused by the HT spark's action on oxygen in the air) could build up inside the dizzy, and perhaps/occasionally/may etc etc explode and wreck the dizzy. So air is drawn into the dizzy through the bottom side spigot (as shown in Doug's link) and out through the top spigot which is connected to a hose in he B bank induction system. This special hose is NLA, and so are the little plastic connectors. For a friend I made a working system using one of these little jobs on an ordinary 90 degree hose:

Okay, new issue: 3A and 6B spark plugs are stuck. I've had them soaking in WD-40 for about 24 hours and they won't budge with moderately hard pressure on a 3/8 ratchet. I know PB Blaster is supposed to work better, but O'Reilly didn't have any when I went shopping. How hard can I crank on this before I risk damaging the threads in the cylinder head?

 

I use a long extension so I can stand pretty upright, with a 2 foot lever (a piece of tube) on the ratchet handle, with steady pressure gradually increasing, and the plug will suddenly start with a loud "CLICK" that will scare the life out of you!

 

Agreed with that.

I use a "brew" of ATF and Diesel Fuel, 50/50, let it soak. WD40 evaporates, not what you want.

Sometimes a day or 2, depends on the beer supply.

When replacing, Anti-seize on the plug threads, and just over finger tight is all that is needed. By that, screw in until the tapper seat JUST contacts the head, then a very short NIP of the wrench, job done. Too much NIP, and you will have this again next time, trust us all on that one.

 

Acetone and brake fluid 50/50. Acetone really creeps through the threads well.
