chapter 7 in my clymer volvo shop m,anual is dedicated to overhead cam motors. it covers aq120,125a,125b,131a,140,145a,145b,151b,and 171a. the 171a is the only diddrent one i can see, it's a twin cam shaft 16 valve.. so there is overhead cam in use or i'm reading wrong..

pushrod or overhead cam?

Generally Speaking,<br />Overhead Valve motors are Torqueier...... Lot's of Power down low...........<br />Overhead Cam motors make their Power at Higher RPMs............<br />

so there is overhead cam in use or i'm reading wrong..

Volvo's are 1 of a Kind....................

A 125 is an overhead cam. It has a timing belt that runs to the head so it has to be.
