Procedure for pushrod:
-Get engine temp to operating temp
-Remove all plugs (wear good gloves, the headers/engine will be yoga balls hot)
-Disconnect coil wire
-Install gauge on 1st cylinder
-Crank engine for about 10 seconds
-Move gauge to 2nd cylinder
General rule is less than 10% variance between highest and lowest reading.
