Hi all,

hoping for a little guidance. I just swapped in a freshly rebuilt B16B into my 97 Civic. I have not started the engine yet. I went and did a compression test and the results are pretty low. Compression test was done with all spark plugs removed, throttle 100% open with the fuel injection system fuse pulled and all injectors disconnected. Valve lashing is to spec (.006 intake .007 exhaust) and the engine was at TDC.

Cylinder 1: 175
Cylinder 2: 175
Cylinder 3: 175
Cylinder 4: 185

Are these numbers ok for an engine that hasn't been started yet? I know the rings will need to seat during break-in, but I want to make sure everything is ok before I start it.

You need to break the engine in and seat the rings before you’re going to get true results.

but yes you have good compression.

do t forget to run a break in oil to ensure the rings seat properly
