I recently acquired another 'teener. See video here.
I have a leakdown tester like the one pictured below. The included instructions are pretty worthless. There is a hose extension that screws into the spark plug hole in the head. The other end connects to the gauge. My question is, do I add air from my compressor and use the regulator on the tool to set the leakdown gauge (on the right) to 0% and then connect it to the piece of hose, or do I assembly everything together and then add air? I tried the latter method and used the regulator to adjust the leakdown gauge to 0% and then it never went down.  |

I know that the HF stuff is not high quality, or even average quality. I called three local auto parts places and they didn't sell them (one didn't even know what I was talking about (IMG:style_emoticons/default/WTF.gif) ).
I figured that if I bought a good one online for $100-150, I'd still probably end up with one with gauges made in China. |

QUOTE(Cevan @ Jul 2 2008, 02:35 PM)  I figured that if I bought a good one online for $100-150, I'd still probably end up with one with gauges made in China. The gauges on my Longacre leakdown tester do not specifically state country of origin, but they are marked USG which is an Ametek trademark. This still doesn't tie down country of origin but Ametek is a US company with an excellent reputation. The pressure regulator is Parker and does indicate 'Made in Mexico.' The problem is not China, although given my druthers I prefer to avoid them too. The problem with China is that they will sell whatever you are willing to pay for, which makes it not so much a China problem as a 'purveyor of cheap goods contracting production in China' problem. Face it - they have the technology to make ultra-high quality electronics and aircraft/spacecraft-rated stuff. If that's what you contract and pay for, you can get it. The problem is that lots of companies pay to have cheap, low-quality goods manufactured - it's a real buyer-beware environment. You can buy a $50 drill press or a $500 drill press and you can get what you pay for; just don't be expecting a $500 tool for $50. |
