question about compression

[fjfjfj]

Hello you guys,,,,,,,,,,,COMPRESSION on F engine is 145 / 135 / 135 / 125 / 125 / 145. Pig sitting for awhile. These numbers reflect warm engine though. Valves have already been adjusted to Toyota Spec. 1969 FJ55. The numbers seem good except for # 4 and 5. Is there a reason why those are so much lower then the others, especially 1 and 6? Cruiser does not smoke, idles nicely. Comments on those two low numbers would be appreciated. Thanks.

Don't laugh. It's 44 years old. It will not be perfect. As long as it doesn't smoke, leak excessively, make noise, have excessive metal in the oil, has decent oil pressure, and is powerful enough, I would not sweat it. Run it until one of these is an issue. My $.02

Something in those two cylinders are worn alittle more than the rest. That's not bad for an old engine.

I might put a torque wrench on the head bolts, make sure they're all tight...Might try adjusting the valves again, a little bit tighter this time, see if that changes anything. I would not lose any sleep over it though...
