Supertech Valve Stem Seal Set

For 1983–1987 Toyota Corolla AE86 with 4A-GE, plus 1984–1989 Toyota MR2 AW11 and 1987–1991 Toyota Corolla AE92 coupe with 4A-GE or 4A-GZE.

Overview

This Supertech valve stem seal set restores oil control at the valve guides in 1983–1987 Toyota Corolla AE86 with 4A-GE, plus 1984–1989 Toyota MR2 AW11 and 1987–1991 Toyota Corolla AE92 coupes with 4A-GE or 4A-GZE. The set includes eight intake valve stem seals and eight exhaust valve stem seals.

The intake seals use a polyacrylic compound, while the exhaust seals use heat-resistant Viton. The set suits original 16-valve cylinder heads with standard valve stems and factory-size valve guides, including bigport and smallport applications.

Key Features

  • Intake-specific polyacrylic seals control oil at the intake valve guides.
  • Viton exhaust seals withstand the hotter exhaust-side operating conditions.
  • Standard-guide fitment matches the original 6 mm valve-stem application.
  • Bigport and smallport coverage serves the supported original 4A-GE and 4A-GZE cylinder heads.
  • Complete-engine coverage supplies both intake and exhaust positions in one purchase.

Fitment Notes

  • Original 16-valve head and standard-size guides: supports 6 mm valve stems and the factory 11 mm seal-mounting diameter on the guides.
  • Not for 20-valve conversions or replacement guides that require smaller seals. Modified cylinder heads require the seal size to match the actual valve stems and guides.
  • Valve stem seals do not repair worn valve guides or other causes of oil consumption.

For the other sealing components involved in this repair, the Stone Front Camshaft Oil Seal Pair supplies both front camshaft positions. The MAHLE Original Valve Cover Gasket Set suits only the matching early naturally aspirated 4A-GE one-piece center-cover arrangement and excludes 4A-GZE; its year and cover restrictions differ from those of these valve stem seals. Camshaft seals and valve cover gaskets are sold separately.
