I had to pull the passenger side header out to put a dent in it due to a small fit problem.When I pulled it out I noticed 2,4 and 6 had what looked like oil coming out of the exhaust ports on the head.2 and 4 were the worst.It makes a stream down the bottom of the port and makes its way to the top a little.This is a rebuilt 350 in my 77 camaro I have had a little miss in it since I first cranked it up.It only has about 2hrs running time on it if that.I ran a compression test and they were all around 165 to 185 after about an hour of running time.I ran my finger down the stem to the base of the valve and they are covered with this oil.I also pulled the other header to check those ports but they were dry.The plugs are all black on the passenger side with what looks like a rich mixture not oil,on the drivers side the plugs look just a little rich not to bad.Could the rings not have seated on those cylinders?Could it be a intake gasket leak pulling oil into the intake runners down to the cylinder also causing the miss and rich plugs.The plugs dont look to have any oil on them.And I havent noticed any smoke at all.I dont have a leak down tester so I havent checked to see if anything is wrong that way.I'm thinking about pulling the intake and the passenger side head off to see if oil is on top of the pistons but I dont really know what to do.I always get some great advice on this site so here I am begging again.Anyone have any advice.
This was to be my little bracket motor,11.1,solid cam,iron eagle platinum heads,vic jr,just your normal 400 horse small block.
