valve covers on 2.8

When removing the valve covers on the 2.8 does the intake manifold have to come off? It seems to really hang over the valve covers.

thanks.

you mean the plenum, the intake manifold is below that, and for the valve covers yes you have to take off the plenum

Its three pieces; the plenum (top), the runners (middle), and the base (manifold). Yes, the plenum and runners have to be removed in order to remove the valve covers. With Redraif's new Trueleo intake, that will no longer be necessary!

Trueleo makes custom intakes for V6 Fieros that make much better power than stock, and we sent them a stock F-body intake so they could alter their design to fit. Hopefully we'll have it in a week or so.

Ok, when the runners are removed, can the fuel rail and injectors stay on it (and just disconnect the fuel lines) or do they have to be removed first???
