Thread: Normal Valve Noise

Tweet

The sewing machine sound is not uncommon but not normal. Most common cause for the noise you can't get rid of is worn rocker arm tips. The VW engines rarely get regular valve adjustments and it puts a wear pattern on the the tips and the feeler gauge can't compensate. Did you use the 180 degree rotation when you ran the valves or at least have both valve covers off to double check the back side of the cam for exact placement of the cam lobes?

yes to all of your above questions nitrowarrior. I started at #1 cylinder at TDC, the distributor was firing that cylinder, adjusted the valves, then rotated the engine 180 degrees COUNTERclockwise to get #3 cylinder at TDC, adjsted them, then another 180 counterclockwise, etc.
