I'm talking about the sheet metal baffle under the intake manifold. After I remove the screws I assume that I can replace them with small bolts and lock washers?
Also, there is a steel mesh fabric in the rear section of the baffle, apparently to reduce oil flow to the down draft (or pcv) system. I'll try and soak this in solvent to clean it but if I can't get it clean I'll have to replace it. I'm not sure what type of material would be appropriate to use as a replacement.
