Re: Getting my 84 silverado C-10 back on the road
Well is been a little while sense I posted an update. So far I have primed the oil pump, replaced the missing battery support bracket and overflow tank. I removed and replaced the gas in the tank. bought a battery and poured some Sea Foam in the carburetor and let it set for a week. So last night I got enough nerve to try to start it up. I sprayed a little starting fluid in the carb and gave it a go. Fired right up! Unbelievable. Oil pressure went to normal and the idle was high but then backed of slightly once i taped the gas peddle. I let it get up to temp and some smoke developed down by the valve covers so I shut it down. Let it cool down some then tried it again. Fired right up again... awesome. Do you guys think the smoke is just some seepage over time and will burn off? Or should I replace the valve cover gaskets? Also the high idle I don't know what to make of that. Next thing for sure is the trans fluid and filter. I've never replace this gasket before, is it tough to do on the ground?
Thanks, for your help guys!! |

She would idle at higher RPM for a minute or two till the choke warmed up. When I tapped the gas she idled down. If the throttle butterflys are a little sticky she might stay up at 900 or 1,000 till you drive her a bit.

Re: Getting my 84 silverado C-10 back on the road
Thanks guys,
That's exactly whats going on. I been looking at valve gaskets for replacement and there are a lot of choices. What type and brand would you guys suggest? Also I have new electric window switches I need to replace, do they just pop off with a little prying or is there a trick to this. I don't want to wreck my nice door cards. |

Re: Getting my 84 silverado C-10 back on the road
Hey Schultze,
I would take off your door panel to replace the window switch. There are "spring clips" that push against the back side of the door panel to hold the switch in place. It doesn't seem like prying from the outside would work, but I've never tried it either. Once you get the panel off, you can squeeze the clips together and push the switch out through the hole in the panel. See pic (pardon the wiring, it has since been fixed ![]() Good luck with your truck! |

Re: Getting my 84 silverado C-10 back on the road
I have had better luck with the black rubber like valve cover gaskets than the cork. I usually clean surfaces with starting fluid, and put a small amount of sealant on both sides of the gasket before installation. Some guys don't agree with this step, but I do it anyways.....

Re: Getting my 84 silverado C-10 back on the road
I've always been told to use Fel-Pro as brand and cork as the material.. As you found out, there is tons of gaskets! Read reviews, for example on summit racing or wherever. Eliminate the ones you don't think you'd like to run.
