Review on πŸ”§ Dorman 46038 Engine Crankcase Breather Hose: Reliable and Efficient Solution for Proper Engine Ventilation by Viswanath Lopez

Revainrating 5 out of 5

Fits well as OEM and tighter MY

This is an exact replacement for the vacuum line at the rear of the intake manifold on a 5.4 liter Ford 2 valve V8 engine. If you have a check engine light for both banks of cylinders, check this part before assuming the worst of a leaking intake manifold gasket, which is kind of a do-it-yourself nightmare. The installation of this part is about a 4 on a scale of 1 to 10. Time will tell how durable the rubber is, but it should last about 20 years as a Ford OEM part, which exceeds the remaining life of my truck.

Pros
  • Durable finish
Cons
  • Operating speed
