• Valve stem oil seal - improved

    £0.75

    Improved valve stem oil seal.

    These improved stem oil seals have an internal ridge / lip that fits into the groove on our modified valve guides.  The top of the seal is fitted with a tension spring to improve the contact with the guide.

    They are a vast improvement over the poorly designed original stem oil seal.

    Price is for one seal only.  Eight are required for the complete engine set.
