Compression test results (1 Viewer)

Chasing a misfire so did a compression test on my '94 FZJ80 with 300,000+ mi.

Here are the results:

6- 203
5- 183
4- 189
3- 185
2- 187
1- 185

The plug on the #6 did look like maybe it's not firing well/at all?

Am I correct that this compression is ok? Do I need to do a leak down (don't have a gauge yet)?

Thanks, you guys are great...

Those results look pretty good. Did you notice any oil around the plug leads as you removed them?

A very little bit, what does that tell me?

I had done the Valve Cover gasket and plug seals maybe 6 months ago. At that time there was quite a bit of oil in the #4 cylinder.
