Begin by cleaning off the surface of both housing and intake mating surfaces. Remove all gasket material and glue with acetone and a gasket scraper.

Begin by cleaning off the surface of both housing and intake mating surfaces. Remove all gasket material and glue with acetone and a gasket scraper. True the surface of slight imperfections by using a mill/bastard file place flat on the gasket surface working the file back and forth. The shiny spots are the highs and the dull ones are the lows, true these surfaces. When a flat surface is obtained,paint the surface with Dykem dye, lay a new gasket on the surface and insert the bolts in the holes of the intake to center the gasket over the openings. With a scribe, scratch along the gasket edge around the opening. When complete, remove bolts and gasket. This will reveal a scribed line in the purple dye that you will be enlarging up the opening to. |
*If this is an aluminum intake, chuck up a open cut burr that is used for aluminum, and spray it with WD40 or similar lubricant. This will make cleaning the tool easier, reduce friction and heat. | *If this is an aluminum intake, chuck up a open cut burr that is used for aluminum, and spray it with WD40 or similar lubricant.
