		Technical problem- Detecting manifold leak |

 Old trick
 From the 215V8@yahoogroups.com
 
 
  - Hello Bill,
 
  
  - I would strongly suggest you retrofit a vacuum canister to your distributor.
 
  - It will greatly help in smoothness and mileage. Also, I would only use manifold vacuum and not ported. I cannot think of any performance builders (street or tract) who recommend ported 	vacuum.
 
  - That may cure your problem but I think another gremlin is at play.
 
  
  - That aftermarket intake manifold may have a vacuum leak between it and  your heads. I have experienced that problem on  one of my own installations.
 
  
  - Use the old trick of spraying starter fluid around the gasket sealing area  while the engine is idling.
 
  - If there is a noticeable change in RPM you have found the culprit.
 
  
  - Best to you,
 
  - Darius
