Raul Tejada, the Mexican ghoul handyman found captive at Black Mountain, must be the player's active companion when the player talks with one of the three NPC's, Ranger Andy in Novac, Corporal Sterling in Camp McCarran or Camp Forlorn Hope or Loyal at Nellis Air Force Base. At which NPC you activate the quest doesn't matter, just talk and exaust all tree dialogs and Raul will start the converstation with you when you finish talking with the chosen NPC.

Quick walkthrough
The player must:
 * Speak with Ranger Andy in Novac
 * Let Raul speak to the player about Ranger Andy.
 * Travel to Camp McCarran or Camp Forlorn Hope and speak to Corporal Sterling.
 * Let Raul speak to the player about Sterling.
 * Travel to Nellis Air Force Base or Black Mountain and speak to Loyal.
 * Let Raul speak to the player about Loyal.

Note: after quest Volare! Loyal will travel the the vicinity of Black Mountain and can get stuck inside the mountains polygon mesh. PS3/X360 users should do this quest before completing Volare!, while PC players can help themselves with the console command

Note: if you met Ranger Andy in Novac and learned his Ranger Takedown technique without Raul present, you will have missed the opportunity to complete Old School Ghoul. Players of the PC version can correct this by using the console and typing the following exactly:  This *must* be done in an indoor area. Transition to an outdoor area and Raul should initiate conversation.

Also, if you are not able to access Raul's story after speaking with Corporal Sterling, you can input a similar console command:

Detailed walkthrough
After speaking with Ranger Andy and learning the takedown move, (Note: if you received the takedown move before Raul has joined your party, he will not speak to you upon exit of Ranger Andy's bungalow.) Raul will initiate a dialogue concerning the player's opinion of Ranger Andy's place as a crippled, older man in a harsh world. The choices made by the player will influence which way Raul decides to proceed at the end of the quest ultimately affecting the player's reward. The player has an opportunity to hear part of Raul's story but may skip this portion of the dialogue at no penalty.

The player must then travel to either Camp McCarran or Camp Forlorn Hope depending on the completion status of the quest Three-Card Bounty. The player must speak with Corporal Sterling, a 1st Recon NCR sniper stationed with the rest of his squad at Camp McCarran, defending the region against fiends. If the bounties have all already been turned in to Major Dhatri during the quest Three-Card Bounty, his squad will have been reassigned to Camp Forlorn Hope. After initiating and ending conversation with Sterling, Raul will initiate a dialogue similar to the one held after learning the takedown move from Ranger Andy.

Upon completion of the first conversation, the player must travel to Nellis Air Force Base and initiate a similar conversation with Loyal. He can typically be found in either his own house or the hangar housing the bomber. After ending the conversation, Raul will initiate a final conversation wherein he ties the stories of the three men the player has met thus far to his own story. He will decide to either return to his gun slinging vaquero ways or relegate himself to a quieter life of machine (and armament) maintenance. The decision at which he will arrive is influenced entirely by the player's dialogue responses during the progression of this quest. However, the player has the opportunity to sway him to the other alternative with a speech skill of 66.

After completing the final dialogue, Raul will receive an upgraded perk. Old Vaquero if the player convinced him to return to the ways of his gun slinging past increasing his fire rate by 33%, or Full Maintenance if the player urged him to contribute in other ways increasing the reduction in weapon damage that he provides from 25% to 75%. His outfit will also change to the Vaquero outfit or the Armored Petró-Chico outfit appropriately.

Bugs

 * Some players have reported being unable to talk with Corporal Sterling. He only replies with a generic line without opening dialogue if he is stationed at Camp Forlorn Hope.
