friend mis 4 and hit 2nd instead.... i want to do a compression check.

-can someone tell me the comp. ratio on a F23A thanks

-and the procedure pls

 

As long as all 4 cylinders read the same (or very close) number, it's fine.

Examples.

180 180 180 180 = Smooth sailing.

180 180 180 155 = Houston, we have a problem.

You can buy a tester at your local Pep Boys, or AutoZone. Around $30.

 

10 percent or more different between cylinder=engine going south

autozone rent them out for free i think

 

You can rent them? Since when?

 

thanx for the replys...

did compression check results

4 (230) 3 (210) 2 (210) 1 (215)


# came out pretty good... i told my friend to memorize wich lines to match on the distributor and he didnt .... first attempt to start the car( sounds like a freaken CAMMED 5.0).... after 5-6 times of trying and error finaly go the car started....

 

Aren't the stock wires numbered?

I'm pretty sure they are.

 

lol plug wires are # but distributor are not lol.... he put back his stock PLug wirez.... cuz he broke the OBX ones hahah OBX wut can i say.......

 

Isnt that compression a little high for the F23A? IF its anything like my F22 it should be around 180.

 

f23 has higher compression than f22

the numbers are also related to the number of times you crank it

 

isnt it the same? i think the F23 accords are 9.3:1 right?

 

f23 vtec motors are 9.3:1
I'm pretty sure f22 motors were in the high 8s:1
