Am needing to do a leak down test and was wondering what type of set ups do y'all use?
They make actual leakdown testers for that purpose. I think I saw one a harbor freight for like 29.99 a couple of years ago. Some others that I have seen go for about 70.
reynoldston said:Just what do you mean by a leak down test? You can do a test by putting compressed air in the cylinder to check how much air leaks by the rings and valves. Why do you want such a test. If that is what you are talking about, as for myself I have a fitting that fits in the spark plug hole with a hose on it an a quick disconnect that gos on my air hose. Do the test on TDC and hold the flywheel. Or are you talking about a coolant leak and want find the leak? Maybe a tire is leaking air? Need a little more information??
Reynoldston... What type of fitting is it you have. That is the same thing I was thinking about but that was how we done it on a 4 stroke. We just used the handheld pressure vac pump on 2 stroke. But I still need to find that fitting.
It is to test the crankcase and cylinder to make sure there are no cracks causing it to suck air allowing it to run lean and it also checks the gasket or sealant to make sure there are no leaks.
Yes you would apply vacuum through the spark plug hole. The mighty vac pressure/vac pump allows you to check both without disconnecting anything.
