Hello,
New Member with a new to me 2001 Corolla LE Auto USA 1ZZ-FE engine 70K miles (mother-in-laws, now mine).
Trying to find small bits like PCV valve and Spark plugs and Toyota often lists two different parts for this engine with no explanation why the difference, even when I input the VIN.
Fur instance:
PCV Valve - either 12204-22041 or 12204-122051
And Spark Plugs - either 90919-01217 or 90080-91184
What's the production difference? These apparently overlap production dates.
Thanks very much!
