If it isn't one thing, it's another.
The one thing is I was going to check the wiring from the dimmer switch for my gauge lights so I can run a wire from there to where my new gauges will be.
The panel that holds my headlights and the dimmer only takes two screws to get loose but the bundle of wires is short which makes it hard getting the plugs unplugged.
Once I got the panel removed I noticed one of the wires had a bare spot in it. I grabbed a light to get a better look at the situation and realize that same wire has a bubbled appearance indicating it's been rather warm. It appears to be a ground wire but I can't find a description with the color codes.
It gets even more fun. To hold the dimmer knob and the headlight switches in place is a metal bracket with two screws at the top and two screws at the bottom. They of course screw into plastic. In the '80s and into the '90s GM used the crappiest plastic ever created. To add insult to injury they made it thin.
One of the bosses that holds the screws was still intact. The bottom runs were actually gone and one of the top ones was cracked.
I probably spent 2 hours getting a piece of plastic to replace the lower bosses and then cut reinforcements for the upper bosses to reinforce them. JB weld quick is your friend. Love that stuff.
While I had a torn apart I opened up the rheostat and polished up all the copper contacts and contact surfaces. I won't know if the dimmer works better than it used to or not at least not until tonight.
Basically all I got done today was worry about a ground wire that's gotten hot. I have no idea how to get in there and replace it because the wires are tucked too far into the dash to do a repair and the cavity is only about 2 in by 5 in. Not much room for wire strippers and fat hands.
Oh wait it gets better.
I replaced the gasket in the bottom of the throttle body a month and a half or two ago and while I had it off like I gave it a spit shine inside and out.
The engine has had a slight stumble for a couple of seconds whenever I start the truck. I decided to look into the throttle body again and see if there was any build up, which there shouldn't be because I just, ....I just cleaned the damn thing.
There is a vent from the rocker arm cover directly into an air cleaner spacer in the back of the throttle body. That hose was plugged up totally when I had the throttle body off and was cleaning it so I cleaned out the hose too and for the first time in a long time, my PVC system was functioning.
Okay, back to the stumble I was trying to get rid of. This is what the back side of the throttle body looks like. It was shiny metal a month and a half or so ago.
Okay, that's obviously from moisture. I searched around and discovered where it's coming from. The intake manifold gasket is apparently not in the best of shape. There's a water crossover passage on the back side of the intake manifold that feeds both heads. This is one time where moist is not good. I'm thinking it may be a slow drip into the lifter valley that's just enough to evaporate continuously and get sucked up through that vent tube. The oil is not milky at all it looks great.
I pulled the spark plugs on this side of the engine and if water was seeping into the intake then the plug should be white and clean because water in the heat pretty much steam clean the porcelain. The one closest to the leak had a reddish tinge to it. That's not from water so I don't think any water is getting sucked into the cylinder. I don't think a leak into the head could cause the moisture getting into the oil. And since I can now see some bubbling on the backside of the intake manifold I think it's just that gasket.
This is not going to be fun to fix. I'm hoping some stop leak, some of that Silver Seal aluminum stuff we'll make a temporary fix.
