Yes, the intermediate nodes do modify the Route Request. They increment 
the hop count value.

Nodes receiving a RREQ create or update a route to the sender of this 
particular IP packet. Although this sender may not be the originator, 
the IP address is still known from the IP packets header. Unfortunately, 
the sequence number of the sender of the IP packet is not known.

Afterwards the node creates or updates a route to the originator of the 
route request. This time, the sequence number is known from the RREQ 
message.

No other modification is made.

Does that help you?
