• Hello
  
  My engine appears to be ok after removing the head. Although I can hear
  a psst sound at the injector no.1 I tried retourque but it did not help that much. I removed the injector and checked the crush washer it a smal dent on one side that apears to have been caught in the threads during assmebly I will try to replace the crush washer see if that helps.
  
  I was wondering if you guys have any other method of improving the seal in the injectorsand glow plugs. Do you think I can use the teflon tape used in plumbing without causing damage to the injectors?
  
  thanks

• I think teflon tape would be a bad idea. Is that stuff heat resistant?

• It's suppose to be heat resistant.
  
  Anyway after replacing the heat sheild three times it seems to be ok now.
  
  There was a small but deep scratch in the injector seat that seems to be causing the problem.
  
  thanks
