A new Melling high performance pick-up tube/oil screen assembly provides the lubrication oil as well as protection for your oil pump from materials that find their way into the engine oil supply system. Contaminates enter your oil system via engine wear, extended time between oil changes and other internal engine sources. These contaminates can interfere with the proper oil flow and pressure spring functions resulting in engine damage and/or failure. Melling suggests that a new properly installed high performance oil pump pick-up tube/screen be a part of every oil pump installation when a higher quality oil pump screen is required. Melling high performance oil pump pick-up tubes/screens are manufactured with stronger welds and in some cases designed with additional reinforced mountings, include mounting bolts and are supplied with protective coatings.

These Mr. Gasket cam buttons are an absolute necessity for roller cam installations and useful to maintain accuracy in any cam installation. Cam buttons keep the camshaft from moving in and out and causing erratic timing. A camshaft button, or camshaft thrust bumper installs into the hole in the front end of the camshaft and prevents camshaft walk in roller camshaft applications. Flat tappet cams are ground with a small angle in the lobes that puts a side load on the camshaft. Without this a camshaft has a natural tendency to move or walk, out of the block when rotating. Roller cam lobes can’t be ground that way so engines originally equipped that way usually use a retainer plate to secure them. The camshaft button serves the same purpose, but it does so by contacting the timing cover to prevent further movement. A worn or missing cam thrust bumper will result in too much end play, resulting in timing issues.

Product Features:

• Mandatory to prevent cam walk in roller cam conversions
• Helps maintain accurate timing
• Made from aluminum
