Re: Leak Down Tester

Keith,
Now you've hit on something I know about.  According to our engine builder at 
Labonte Racing, you should set the first gauge at 100.  Make sure the piston 
you are checking is at TDC (or it will rotate the motor and generally P___s 
you off).  You should not have readings above 8% or so, but the real check is 
the differential between cylinders.  Also, make sure the engine is at normal 
operating temp.  My 2 cents, but hey, I do it every week.
