At least they are all even. The last thing I checked the compression in was 330-370.

then those are pretty low.....

Should have at least 150 across the board.

Has the engine been sitting for a while?

I've seen the weirdest compression numbers from engines that have been sitting for a while. like 215, 215, 155, 105.

Drove it for a while and they even'd out.

no, you test compression on a warm motor.

If your motor was warmed up, and threw 110 across the board, that is low. Usually you want 150 minimum.....having even numbers is more important.

Like I said tho, if the motor has been sitting for a while, take it for a drive. It is pretty common for the numbers to go up if it has been sitting.
