Aluminum Riser for 4.2L Engine?
#1
![Default](/forum/images/icons/icon1.gif)
Is anyone aware of an aluminum riser for the 4.2L engine (Shown in the attached, pictured above gasket #24). When replacing my thermostat housing, riser and water pump, I noticed that an area of the riser's top sealing rim was sheared or cracked off.
I know the 4.0L solved plastic thermostat housing crack issues by reverting to aluminum. Just curious if the same de-evolution has yet occurred for the 4.2L engine, as well.
Thanks for any positive leads.
