JohnnysEG stopped by tonight with his new compression tester gadget he got for X-mas. Thanks again man :thumbup:

So, I wanted to check the compression on my 96 Cx that I picked up last week. This way I know if it's worth tuning up for daily driving or pulling the motor and getting a swap. We pulled the ECU fuse, removed all the spark plugs and did the test.....

What all 4 cylinders showed:

Here's a vid (digital camera) of us doing the compression on my Cx. We read how to do it from c-speed's "How To"

4.51 mb **right click save as** 4.51mb

So, how'd we do?

My (FastAssH22Accord) bro's 95 F22 Accord....

8.90mb **right click save as** 8.90mb

Did we do the compression test correctly? I find it odd that all 8 cylinders tested showed at least 180. My bro swore the thing was broke after we did his 220K+ motor :crook: One of his cylinders showed 205

As always thanks for any feedback

As long as you did the following :

- engine was warm
- throttle was wide open
- you released the pressure on the guage after reading each cylinder

then you should be fine. I got a compression tester for Christmas as well

Guess I'll be doing it again....

As long as you did the following :

- engine was warm

Ice cold :mad

- throttle was wide open

Forgot to do that :mad

- you released the pressure on the guage after reading each cylinder

:clap Got that one :rolleyes

then you should be fine. I got a compression tester for Christmas as well

I was going to buy about $175 worth of parts today for a tune-up. Now I've got to retest the compression instead and still hope it's good :aww

I took my car for a "spirited" drive before doing a compression and leakdown test. If I ever get off my butt, I'll do the write-up on the leakdown test. Anyways, be sure to post up the new numbers after you retest.

 

[iLLeFFeKt CiViC]

the numbers are supposed to increase if you hold the gas pedal down this time around correct?

 

[kommon_sense]

yup... the engine has to actually be able to suck in air in order to compress it and have the compression tester give an accurate reading...

I just keep craking the engine over without stopping.

I just keep cranking the engine over without stopping.

yeah, that's what i do too :confused
