I am trying to understand how to use my new leak down testing tool from HarborFreight. I am trying to see if my rings are sealing on my rebuilt motor. I hook everything up and I can hear the air through the oil filler but the gauge reads 0% leakage? I can hear it leaking so I know it is not zero - is the tool broken? (it is HF after all) What is the typical pressure when zeroing out the % leak down gauge? Mine reads 12 psi - seems low but the pressure may be irrelevant when determining leak down?
Thanks! |

Now you tell me! It is identical to others I've seen on the internet - and $26 vs $80. I am on my second one - let's hope it is better?
Can someone clarify the instructions when adjusting the pressure? Some say adjust to 100 psi while the instructions say adjust so the "% Leakage" gauge reads zero. When I adjust the input pressure to 100 the "% Leakage" scale is off the chart. My problem when I follow the instructions the % leakage stays at zero while the input gauge reads 12psi - even though I can hear the leaking through the oil filler. I have not tries my second gauge - hopefully it will be better? I will treat it more gently than I did my last one. |
