Basically a fancy compression tester that tells you if your cylinders are sealing properly.<br />Blows compressed air into the cylinder & measures the % of leak. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>AaronC</b> <br /><small>Member # 86</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2002,10,12,17,13,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> I have a leak down tester. You need an air compressor to use it. Basically you pull the spark plugs out and make sure both valves are shut for the cylinder your testing. then attach the the line from the tester to the spark plug hole. Attach the other end to the air compressor and slowly give it 100 psi of air. The air will compress into the cylinder. The tester has 2 gauges. The first one you set to 100 and the second gauge will tell you how much is leaking down. so if the second gauge reads 90 then you have 10% leak down. It's a good tool because it'll tell you where it's leaking from. Intake valve, exhaust valve, head gasket etc. <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>PeNiNsula302</b> <br /><small>Member # 1061</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2002,10,13,0,35,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> sounds good, thanks fellas! looks like im gonna buy the thing instead of paying some insane rate at a shop... <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Fox89GT</b> <br /><small>Member # 1539</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2002,10,13,9,6,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> AaronC, how does the tool know where its leaking from?

Or in my case I blew my head gaskets between the cylinders and you could hear and feel the air coming out of the next cylinders spark plug hole. A compression test wouldn't have done much. I knew I wasn't getting compression, but with this test, I knew exactly why. Then I knew what needed to be done. <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
