How To: Compression and Leakage Test!

[JDM7o3]

Thanks for the help. A few more questions? Where or how do I do the compression and leakage test on the engine? And If I can do it myself, what do I need to preform the testing?

This is in the wrong forum, the mods will probably move it to general tech and maintenance, but oh well.

A compression test is easy. I haven't actually done a leakdown test, but I know the principle. You would need at least a compression tester to do this. A compression tester is a guage with a rubber hose attached that screws into your spark plug hole. You crank the engine and look at the dial. Hopefully all four cylinders read about the same. A leakdown test is to find out how fast the compression leaks past the piston.

A combination of these two tests is a fairly reliable way of checking a motors condition. Nothing is foolproof.

I'd have a shop check it. It can't be that much.
