Toyota Tercel 1984-1994 Repair Guide

Valve Guides



Replacing the valve guides involves heating the head to high temperatures and driving the old guide out with the use of special tools. The head may have to be machined for an oversize guide if the bushing bore dimension is over the standard specifications. The new guide is then reamed for the proper valve stem-to-guide clearance. This repair requires a high level of mechanical skill and should only be performed by a reputable machine shop.
