F130 Compression Readings

Followed instructions with compression tester and got the following readings on the F130 with C123 engine.
1=125 PSI
2=125 PSI
3=125 PSI
4=125 PSI

Good readings for this engine?

The manual states compression as 6.5:1 ratio, but that's greek to me

Also got some wierd squeaking noise while checking #4, maybe a stuck intake valve?

I knew GW had went over this with me before. Way back in '03.

I should be happy with 125 PSI on the 130.

Those are good readings. Especially if they are dry readings.

Can't be too stuck with that compression.
