On the 1997-2019 Ford E-Series, the modular Triton gasoline engines fitted to the E-Series - 4.6L V8, 5.4L V8 and 6.8L V10, all 2-valve in this van (the E-Series never received the 3-valve heads used in F-Series trucks) - break their exhaust manifold studs where they thread into the aluminium head. Repeated heat cycling plus road salt corrodes and fatigues the factory studs, usually the front-most one on each bank. The result is the classic 'Triton tick' that is loudest on cold start and quiets as the manifold expands, and it is frequently misdiagnosed as a lifter or an exhaust leak at the gasket.

Common Symptoms

  • Ticking or puffing noise loudest on cold start
  • Exhaust smell in the cabin
  • Tick quiets as engine warms
  • Soot staining around the manifold flange
  • Failed emissions test from an upstream leak

How to Fix

Locate the leak by feel or with a smoke test, then remove the manifold and extract the broken studs - usually by welding a nut to the exposed stump or by drilling and using an extractor, with the head in place. Ford supplies an updated stainless stud, P/N W703902-S403, with nut W701706-S2; the manifold gasket must be replaced at the same time and the studs torqued to 71-115 in-lb with the nuts at 204-239 in-lb. No recall exists; it is a wear repair.

Typical repair cost:$400 - $1,600
