I had my 455 re manufacturied by S&J engines in Spokane a couple of months ago. I had roller lifters, roller cam and roller rockers installed along with oil restrictors. I had S&J install the intake manifold and all sheet metal. I figured this was the safest way to insure a good running engine without any leaks. Manny Trovao started the engine as prescribed by S&J, ran for 20 minutes at 2000 rpm. After 700 miles I changed the Joe Gibbs break in oil to Mobile 1 15-50 and left for Alaska. On the way to the Cascaders Covered Bridges rally I used one quart of oil every 140 miles! There was no smoke from the exhaust, plugs were not fouled and there was not any apparent oil from the rocker cover vents. The technician at S&J thought that it might be an intake manifold leak and suggested that the manifold be resealed. I convinced Jim Hupy to reseal the intake manifold after the Covered Bridges rally. I spent three days at Jim and Judy's house carefully removing cleaning and resealing the manifold. Used new Dick Patterson gaskets and block off plates. This surely would solve the oil consumption problem. I continued north to Alaska and after another thousand mile it was still using 1 quart of oil every 140 miles, no improvement. S&J suggested changing to conventional oil so I changed oil and filter to Shell Rotella 15-40 in Dawson Creek. Since then I have driven 2000 miles and have used two gallons of oil. An improvement from 1 quart/ 140 mi to 1 quart / 250 miles. I now have about 4500 miles on the engine and oil consumption remains constant at 1 quart/ 250 miles so. I just add oil and check the gas!
