The original plastic spark plug tubes installed in early (’99-’01) 996s and (’97-’02) Boxsters leave a lot to be desired. The plastic tubes are not round. O-ring seals need very round, smooth surfaces in order to work properly. Plastic tubes often have molding flash in the o-ring grooves. This keeps the o-ring from contacting the seal groove evenly, preventing a proper seal. They have structural issues at the mold parting lines (seams) which cause weak spots. Plastic tubes are basically an oil leak just waiting to happen – and it will.
