Oil Burning 390. Help!! |
By Phill Rose - 02/02/2001 5:23:18 PM; IP 207.90.122.116 |
My name is Phill Rose and I have a Pre-65 390FE Ford engine. It is between a 66-76 engine. I believe it is a 68. I had a standard long block done at a local engine builder. Since I put the engine back in my truck it has smoked a good bit. Blue smoke like it is burning oil. It does use way to much oil, about a quart every 40 miles. I am no engine expert but I think that is way to much oil. I have about 350 mile on the new rebuild. I contacted the shop that rebuilt it and they said that I probably did not get the intake manifold sealed correctly. I pulled the intake after they said this and used high temperature gasket sealer and was careful not to use to much and to also make sure to seal at the corners were the heads and block meet. I used the cork gaskets on both ends of the intake and the gaskets were the intake and heads seal together. I do not have any external leaks that I can see. The engine is still burning oil. I called the engine shop back and they still think that the intake is not sealed properly. They have not been much help. I was told by another person that if more than .020" is machined off the heads that the intake manifold must also be machined. Is this true? I also did a compression check on the engine and all the cylinders checked 150psi, but the plugs where terribly oil fouled. The engine seem to run strong and does not seem to miss. I am using the recommended motercraft spark plugs in the truck. I think the intake is sucking the oil up from underneath where the intake meets the side of the heads. I don't know for sure but I think the heads have been machined before. My next step is to pull the intake back off and try not using the cork gaskets to see if that lets the intake drop down any farther. If anyone can help me in any way please contact me. Thank you for your time, Phillip J. Rose
