Engine Vacuum Baffle with AN Fitting
Part No: STR.06.11.001Retail Price
$39.00The Star Machine Baffle is designed to reduce the amount of oil scavenged from the crankcase by the vacuum pump. The Baffle is shielded on four sides and open on only one side. This Baffle is not a cure-all for engines that leak or have excessive blow-bye. The baffle is designed to be installed on a vertical surface, NOT on the TOP of a valve cover above a rocker arm.
Be sure the location you have chosen does not interfere with anything before cutting. Allow enough room from any edges so the baffle block can be rotated 360°. This will allow the block to be rotated to the best position that blocks the most oil from entering the baffle.
The Baffle is designed to be installed in a 1-1/16†hole and seals via the O-ring provided. If you are using a hole saw to cut the opening we recommend using a 1†saw and file fit the remainder of the opening as most hole saws tend to cut oversize. The most common location is the front face of the valve cover (the surface that lies in the same plane as the water pump). When installed, the opening of the Baffle should be facing down, toward the cylinder head. This is the best position to start, it may be necessary to rotate the block to reduce oil entering the baffle. Loctite the threads once the best position is chosen.
The gap between the radius end of the fitting and the back of the Baffle will vary depending on the thickness of the material in which it is installed. The gap should be greater than 0.18" to not hinder the flow of your vacuum pump. Trim the threads from the of the fitting if necessary. The baffle can be tack welded to an aluminum valve cover but only after you have raced the vehicle and are satisfied with the position.
The gap between the radius end of the fitting and the back of the Baffle will vary depending on the thickness of the material in which it is installed. The gap should be adequate to not hinder the flow of your particular vacuum pump. The ideal size of this gap will vary depending on the combination.
Available with -12 or -10 AN male fitting.
