Doing my first leak-down test and I'm now seeing some results that seem more beleivable.
On cylinder #1, I appeared to have 100% sealing. Is that actually possible, or did I just not wait long enough? On cylinder #2, I get about 92 or 93% sealing. I don't hear anything at the intake or exhaust, but there is a hiss at the oil filler, so I guess this means rings... On cylinder #3, Also close to 95%, and all escapes appears to be through the rings again. Are these reasonable results? What is acceptable? Then engine has not run for several weeks now, so the cylinders may be "de-filmed" Who has experience in this test that can enlighten me? Thanks y'all. Oh, BTW, Roll Tide. |
