New turbine and compressor seals for Holset HX35 HX30 H1C HX40 HX50 HE351 turbochargers. These are the piston ring type seals which are on the turbine and compressor ends of the shaft/wheel assembly. When these seals are worn, excessive oil consumption and oil burning will result. Additionally, oil leaking into the turbine housing may result in residue build-up thus hampering turbocharger performance. These parts are often the first to wear out in a turbo. Upon request I'll email you a pdf of a Holset HX35 manual which will help in the disassembly/assembly of your turbo. Buyer pays $1.65 shipping within the USA. Shipping cost to Canada is $7.50. Shipping cost to UK, Australia & all other countries is $11.80. Paypal accepted.
