Datsun Roadster & Fairlady Early Valve Stem Seal UMBRELLA STYLE

63 - 67 early Fairlady 1500 and the early 1600 Datsun Roadster improved valve stem seal. Works with cast iron and aluminum cylinder heads.
These cylinder heads relied on the British style rubber O-rings affixed at the top of the retainers to control oil from running down the guide. Too bad the spring is open all around its circumference, resulting in early cars being oil consumers with nasty build up on the back side of the valves. In the old days we used to machine the inner valve spring step on cylinder head to install the later # 1692 671/2 - 70 umbrella type seal.

Our seal fits over the guide on early cars snugly and provides the sealing like the late cars without having to remove the head to machine the raised inner valve spring step. These seals are included in all our early head sets and early full gasket sets for both models.

Our seals come with a detailed instruction sheet for installing the seals while the head is on the car.
