Tuerca sellada de la tapa de la bomba de aceite M6

The M8 sealing nuts for the oil pump cover were a relatively new development from Volkswagen in the early 1970s, replacing the plain nut they used previously. VW never produced a sealing nut for the early, pre ´67 engines and we therefore included the M6 sealing nuts in our range, to eliminate any source of oil leakage on older engines as well.These are sold individually and you need 4 per engine.
