Defining characteristics of F120 versus F135

[BTUMAN]

I've searched both here and on the FJ40 section and found some information covering the history of the F motors.

However I have not found good specific examples of the differences between the F120 motor as compared to the F135 motor.

Does anyone have pictures of the F120 motor with a comparison F135 and what the differences were. I understand the distributor was different and possibly the vent tube.

Yes. I found this document earlier. What visably is different?

Based on what I've researched I'll answer my own question- hoping some if can straighten me out if I'm wrong.

The differences between the F135 and F120 were all internal and output related. There are no noticable differences between the two engines externally. Thus, one must use the above notice with engine serial number to know if they have either engine.
