Are these compression test numbers ok?

[bigt61]

Did a compression test on my wifes 92 Accord EX with 240k on original everything. We run syhtnetic mobil 1 10w30, and do service it properly.

She said it was running funny the other day, so I decided to do a compression test on it.

The numbers are as follows in PSI- cylinders are going from left to right facing the engine, standing in front of the car with the hood open.

cylinder 1- 200
cylinder 2- 190
cylinder 3- 185
cylinder 4- 195

Are these numbers okay?

I've got another VTEC engine to swap into there from a 97 accord that I've had for a while, and I'm just waiting on her original engine to DIE to replace it.

What do you guys think?

i think those numbers are great, as long as they are consistent which they are except for number 3. but other than that that engine is gona live forever.

yea, i know number 3 is slightly off, but i didnt think it was THAT big of a deal. The instructions that came with the compression gauge said if it was off by more than 20 pointsthen to be concerned and double check it with oil poured in the cylinder.

lol those numbers are great!!! the P O S f22a1 I bought was getting like 130 across the board (what a peice of shit right?). Of coures, I replaced that motor with my H22a =)

how do you do the compression check. I don't get it I can get the checker thing but yeah. how do it do it properly

[bigt61]

instructions come with your compression guage that you buy. i got my kit at autozone for 20 bucks or so. works great. comes with very detailed instructions as well.

Make sure car is cool for spark plug reasons:
1 buy the guage and kit
2 remove wires
3 remove cyl 1 plug
4 check plug for lean/rich/oily evidence
5 lube o ring on compression tester hose
6 screw in hose
7 snap on guage (depending on type of comp tester)
8 pull ECU fuse from hood fusebox
9 have friend/parent/dog hold the comp tester (not completely nec.)
10 press gas pedal to floor to allow full air in the motor/TB
11 crank over 4-5 times
12 check numbers
13 push air release valve and remove comp tester from cyl
14 replug ur plug
15 repeat for cylinders 2-4

sound good?
