Does anybody know what is difference between two pcv valves for 3.0 engine C2S21129 (AJ812570) and C2S25648?

thanks

 

The C2S2648 is for engine serial number 17663 up to 2002.
The C2S21129 is for engine serial number 173664 in 2002 and all 2003 to 2008.
The easiest way to tell which one fit your vehicle is to look at the base of the valve.

If yours base is green you use C2S25648, if it is grey you use the C2S21129. The bases are a slightly different size.

 

Here is a 15 year old TSB for North America that may or may not help.

I noticed there are two types after i ordered. Ofcourse i ordered the wrong one. i hope the grey one will fit in gplace of green one.

 

The grey one C2S21129 should work for you just fine it was an update from the greeen one internally. There is a sight difference externally but it should fit and orient correctly. Supposed to be better than the grey.

 

glad to hear that, thanks!
