ok so here is the deal i am looking into buying a used 98 H22 for my EG and was wondering what good compression is?? they said that it pulled 160 across all 4 cylinder just wondering what you guys think about those numbers??

Thank YOu

 

i think you should do the compression test yourself before you buy the motor.

 

Yeah, go buy a compression tester for $20 and do it yourself, it's really really easy. I actually did mine yesterday to check up on my engines health after a year of having it, and it was 220 on all the cylinders. Different guages can give different readings, so go get yourself one. Remember to pull the ECU fuses from the inside fusebox when doing the compression test, this will deactivate the fuel pump. And disconnecting the 2 distributor plugs is a good idea too.

not only a good idea, but it will keep you from burning up the coil.

dont forget to hold the throttle open and also crank each cylinder the same number of revolutions. the compression numbers dont have to be extremely high but it is important that they are somewhat even across, within 10-15 psi of eachother.

 

umm 160 is garbage no offence. should be in the 200s

 

that is just it the motor is not in the car

 

your looking for consistency rather than peak numbers however there is a min spec

Are you talking about the wiring in the primart circuit that runs to the coil and the plug coming out of the ingition coil that goes to the cap ?

 

what is that MIN SPEC

Up to 28 psi variation is acceptable (though I'd be worried)

135 psi is min spec..

 

is it say to assume the motor is getting on with it;s life then
