my car is stock and i want to do a compression test on it. it a d16z6. im buying this tester at autozone. what should this guage read on each cylinder if its got good compression? i've been searching but all the archived searches i did were no help. my car feels waaay slower than it used to.

 

you're looking more for consistancy than high numbers.

look for 160+ and no more than 15 PSI between cylinders.

 

thanks ive been looking for something to go off all night . i will do it in the morning and post my results

you know how to do it? wet and dry?

 

i think so. my friend swears that not holding the throttle open wont make a diffrence. im sure hes wrong. what would happen to the readings if its done w/o holding open the throttle?

i did it without and i had absolutely amazing numbers on an old integra of mine.

cant hurt to hold throttle open, so do it. remember to pull ecu fuse if so equipped.

 

my friend said before he swaped his motor he had 60 across the block on each cylinder. he said it wasnt accelerating as fast but it still drove. what do you think would give him 60 to 65 on each cylinder?

 

60?!

on every cylinder?

wow.

how many times did he crank it?

 

till it stopped moving

crank 8 times for about a second each time.

 

60!?!?! either your wrong in the numbers or your friend is driving around a car with **** rings

**** rings would be 120..60...are rings even there?

 

ok smashed ringlands

 

has anybody ever seen a drivable d16z6 with 60's across the block like this?

 

He couldnt have done that right...

 

What happens if you dont pull the ECU fuse?

I just did a comp test on my wifes 95 Civic.. I disconnected the injectors, removed all the plugs, and laid the plug wires to the side. Checked all the cylinders.. which checked out ok... but when I put everything back together the car wont start. Checked for spark.. no spark.

Did I just fry the ECU? I checked all my fuses and nothing was popped.

Thanks.
