Toyota Engine >> VALVE SEAL IDENTIFICATION FOR TOYOTA 1.8L ENGINES
Valve Seal Identification For
2000-2002 Toyota 1.8L Engines
The AERA Technical Committee offers the following information on valve seal identification for 2000-2002 Toyota 1.8L engines. Starting with the 2000-year model Toyota offered two 1.8L engines with similar displacement, a 1ZZ-FE and a 2ZZ-GE designation.
Determining which engine you're working on may be confusing, as many components are similar. Valve stem seals fall into the confusing category, as they physically appear the same at first glance. Original equipment and some aftermarket seals are color coded to ease in seal identification. Refer to the chart and Figure 1 below to help identify the seals once they?re out of their original packaging.
Engine Model Location Coloring Part Number Stem Diameter
1ZZ-FE Exhaust Gray 9008031046 .2152-.2157
1ZZ-FE Intake Light Brown 9091302101 .2154-.2159
2ZZ-GE Exhaust Green 9091302115 .2144-.2154
2ZZ-GE Intake Black 9091302114 .2150-.2156
Valve guides are also slightly different between the two engines, which offers additional means of engine identification. The installed guide height and the guide outside diameter are different as the 2ZZ-GE engine protrudes higher than the 1ZZ-FE. The 2ZZ-GE guides should be .602-.618 above the spring seat while the 1ZZ-FE guides should be .342-.358 above the spring seat.
