If you are running to rich it is possible that to much gas is washing the hole check the oil for gas. cavemate Dec 8th, 01, 12:25 PM hello? joe clance Dec 8th, 01, 07:52 PM worlg products' heads? travis Dec 8th, 01, 09:39 PM How does it seem to run otherwise? Does it idle ok?

I've even heard some people say that a little bit of oil on the plugs means you are getting excellent lubrication, which isn't a bad thing. My opinion is to change it at 1000 (it's recommended that you change it early on a new build), then let it go for another 2000, and see how much you are burning. ------------------ 68 Coupe, 350 4-speed Jim's Camaro Corner (http://www.personal.psu.edu/jxu109/) 383camaroSS Dec 11th, 01, 07:54 AM i run 2050. and if its the valve seals its ok i am getting new heads in feb. thanks for the help. Mr. C Dec 12th, 01, 07:32 AM Chances are if you have oil on plugs it is getting past the rings,this happens sometimes with fresh rebuilds until rings seat but if you did not bore the cylinders during rebuild and installed new pistons chances are you just wasted your money 383camaroSS Dec 12th, 01, 10:56 AM it was bored 30 over so i hope it is just valve seals or it being a new motor. thanks |
