A note about Zinc - ZDDPZDDP is added to engine oils to stop scuffing in high impact areas such as the flat tappets in the VW engine. When the cam hits the tappet, it does so under very high pressure and CAN squeeze all the oil out resutling is a moment of metal/metal contact, ...
flat tappet lifter and the camshaft lobe. In current API SN engine oils, ZDDP has been drastically reduced to prevent long-term damage to catalytic converters. But since race engines do not commonly utilize emission control devices, ZDDP and other additives can be blended to increase protection ...
Engine builders have grown increasingly concerned that current engine oils that are API licensed for new cars and trucks do not provide adequate wear protection for freshly built performance engines, particularly those using flat tappet camshafts and lifters. Royal Purple has addressed this issue with...
The present invention relates to a hydraulic tappet (1) for heat engines, which is installed between a valve stem (3) and an operating member (4), including a guide (5), a cylinder (7) and a piston (8), a high-pressure chamber (18) filled with an incompressible liquid and a low-...

For engines with locktime pumps. The (2) 3907978 studs (short) are to be used in the in-board mounting holes. DEP may substitute 3282371 in place of 3907978 and 3282372 in place of 3915036. M10 x 1.50 M10 x 1.50(Both Ends) x 50 M10 x 1.50(Both Ends) x 55 Eng. Fam. Z 6C8.3...
The inner chamber has either side of the roller circumference drainage openings (12) for the lubricant. Where lateral play is provided between the roller (3) and tappet body this play increases, starting from the centre of the roller towards the end of the tappet on the roller side through ...
The hydraulically adjusted tappet for OHC IC engines is cylindrical, closed to form an oil reservoir concentric with the pressure cylinder containing the piston spring loaded to move in response to changes in clearance between cam back and valve stem end. Resulting cylinder vol. increase is taken ...
