Hi everyone.I have an 86 Chevy Silverado with a mostly stock 305 and 700r4 tranny. The motor has like 270,000 miles on it! About 2 months ago I had the timing chain, gasket, valve cover gaskets, and intake gasket replaced. I put a holley carb on it and it was tuned also. Recently I flew home and my truck sat for 10 days. When I returned, it started instantly and had no problems, but as I was driving home (90 miles) I filled up with regular fuel even though I usually run premium(damn gas prices). The truck was a little sluggish but I thought it was normal because of the fuel. I stopped at a stop street and it stalled. When I try to accelerate, its really sluggish and makes popping sounds. I checked under the hood and played with it a little bit and saw black smoke from the valve covers when I rev it. It also looks like some oil sitting on the intake towards the back, maybe from bad intake gaskets? I did make it back safely. The next day I filled it up with premium and got some fuel system cleaners and sprayed the carb with carb cleaner. Still no help! I probably should add that I pulled the dual exhaust pipes apart so I could have really loud wide open headers because I live on a military base and they dont care. But I'm not sure if doing that for a while will mess with the engine or not. I'm hoping its not a serious engine problem, but I guess that's to be expected with an old vehicle. Any thoughts or suggestions would be awesome! Thanks!
have the same problem?
