MH>TW> What oil are you using. That sounds just a litte long to me.   
   MH>TW> I left the really cold climate areas back in 1951 so perhaps it is the   
   MH>TW> menory?? :-)   
      
   MH>I have done two oil changes since having the new motor.  The first was using   
   MH>regular 10w30 and just recently went to synthetic 10w30.  Can't remember the   
   MH>exact brand.   
      
   MH>The oil type doesn't seem to make a difference.  I just write it off as the   
   MH>this new engine was built.  The mechanic that I have talked to about it told   
   MH>not to worry about it.  Even if something happens, I have a 3 year 100k   
   MH>warranty on it from Jasper.  It runs great, has better pickup then my origin   
   MH>engine (probably due to new plugs/distributer).   
      
   MH>It is just the cold starts.  If I rev it up a few times, it will stop doing   
   MH>noise faster.   
      
   That sounds like a worn Oil Pump not building the pressure fast enough.   
   A short period of noise is normal but a Full minute or so seems too   
   long to me unless the temperature is really cold. If that is the case   
   try 0-20 sybnthetic oil at next change. And of course when the weather   
   warms up change back to the 10-30.
