Default what are good ej22t compression test #s?

what is ballpark for an ej22t with SOHC 02RS heads?

how does 125+- 5ish all around sound.

to me it is good that they are all very similar. Should I take this as compression is good = engine is most likely good?

I have heard this combo runs around 8.3-4 ish to 1

I was expecting higher numbers actually more like 135 or 140.

please respond asap.

Thanks

Todd

This combo is more like 7.6-7.8:1 and those numbers are decent.

Was the motor warmed up? Numbers can change big time when the motor is cooled off.

most important thing is that each cyl is w/in 10 from the others. If you are losing compression it will most likely be in only one, maybe 2 cylinders. Chances of all 4 losing compression and being about the same is not likely.

That being said, those who dont have compression testers, who want a backyard check, do this:

Disable ignition by unplugging coil pack. Crank engine for about 5 seconds straight (car wont start). Listen for what we call, even cranking. There is not points where the engine cranks faster or slower. it should be even.

A trained ear can hear minor compression loss. Major compression loss is obvious.

Yup, being close to each other matters more then the numbers themself.
