pmolitor Posted April 14, 2015 Share Posted April 14, 2015 So I just got my RS back from the shop for the 3rd time... I can't seem to keep exhaust gaskets in it. If I run 2000rpm for any amount of time it blows the gasket. I'm also blowing fuel past the injectors all over the top of the heads. Thought it was the injectors coming apart so I replaced them. The new ones did the same thing. It even ovaled the copper spacers. Any ideas?

41chevy Posted April 14, 2015 Share Posted April 14, 2015 I would almost think a restriction in the exhaust causing excessive back pressure.

Dirtymilkman Posted April 14, 2015 Share Posted April 14, 2015 Thats what I would think. Turbo spinning freely? Mufflers plugged? If it has an old exhaust brake is it stuck?

pmolitor Posted April 14, 2015 Author Share Posted April 14, 2015 This all started after head gasket was replaced. The muffler is a free flow. Could. The valves be out of adjustment? The dynatard? The dynatard isn't hooked up. Quote Link to comment https://www.bigmacktrucks.com/topic/39683-2-valve-blowing-fuel/#findComment-286670 Share on other sites More sharing options...
