Chrysler and Dodge engines concerned

These seals equip the 6 mm stem exhaust valves of the Chrysler 2.4 EDV, a 2,429 cc twin-cam 16-valve four-cylinder, best known under the bonnet of the turbocharged Dodge Neon SRT-4.

The engine carries 8 exhaust valves, two per cylinder. Their seal caps the guide and regulates the oil that lubricates the stem; the FERREA seal includes the original lower spring seat: seal and lower spring seat in one piece.

FERREA exhaust valve stem seals

At the exhaust, the stem seal sits beside the valve that runs hottest in the engine. Once it stiffens or splits, it stops holding oil back: oil runs along the stem and is burnt in the chamber, so the level drops faster, blue smoke leaves the tailpipe and carbon builds on valves and port walls. It must still pass a thin film of oil, without which the stem and its guide would wear.

FERREA moulds its VS1018 in Viton (FKM), a fluorinated rubber it describes as high temperature, to withstand the heat coming off the exhaust valves, and adds a lip spring that keeps the seal tight around the 6 mm stem under heavy engine load. The seal also integrates the original lower spring seat. The 8-piece set fits all 8 exhaust valves of the EDV; the VS1017 inlet seal, in “Poly” rubber, is sold separately.

Technical guide

The brand offered

Based in Florida, with a second site in Argentina, FERREA builds valves, springs and guides, as well as valve stem seals, for tuned engines and motorsport. Its seals receive an integrated spring that keeps the lip clamped when the engine is pushed hard.

Why two different materials?

The exhaust valve gets much hotter than the inlet valve. FERREA therefore keeps Viton (FKM), rated high temperature, for the VS1018 exhaust seal and a “Poly” rubber for the VS1017 inlet seal; both keep a lip spring. The EDV engine needs 8 seals on each of its two sides.
