What it does
Intake valves let the air and fuel mixture into the cylinder; exhaust valves let the burned gases out. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.
Installation & tips
- Have the valve seats cut or lapped so the new valves seal fully.
- Valve stem seals: Always new with new valves.
- Head gasket: The head comes off for this job.
- Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
