Bad rings? Sr20 compression reads 150 on all 4?

[Keefs240sx]

Have compression tested 150 across done leak down test an showed leakage but no smoke at all running drives fine as well just jumpy idle, could valve seals be bad? Or what lost for words an ideas right now all help needed

[silviaNC]

Det? As far as i know 150 is good

[fliprayzin240sx]

150 is good as long as theyre all within 10-15 psi across the board.

[Keefs240sx]

Sr20det rwd an yea 150 across them all

Leak down showed leakage on test but it doesn't smoke when it's running just idles jumpy

Had all electrical checked an its fine

[Shift n Drift]

i would just beat on it everyday and start to worry after i saw smoke...

Iacv?

could be a bent valve. the question is HOW MUCH leakage on how many cylinders?

[Keefs240sx]

New iacv was put on no fix un plugg maf an it idles out smooth its crazy

[Keefs240sx]

I'm kinda leaning to valves possibly

Mine did that as well. It's was just a wiring issue. I used a hks grounding kit and my problem went away. Also my compression was 155 across all cylinders on a cold motor. So 150 ideally isn't too bad.

150 is good.

Where was your wiring problem near ecu or up close the motor in the bay?

Did your car show leakage or bent valve or did you mean that by the maf an idle on wire problem caused jumpy idle?

[OrangeVirus1]

There will be some leakage on all engines. just depending how fast it leaks..

150 is good, no smoke is good, why complainin bro

[fliprayzin240sx]

I'd start with the usual suspects for jumpy idle, base timing, fresh plugs, sea foam in the gas tank, check for vacuum leaks and clean the IACV.

Then you either have a maf that's going out or a vacuum leak if you say electrical is fine.

replace maf of wiring to the maf might be bad?

[Keefs240sx]

I've tried differ mafs only worried about the idle don't wanna get in traffic an it die on me haha how critical would injector orings be cause it? What would sea foam in the gas tank do? Not being an ass just curious I've heard of ppl letting it suck in a vacuum line before

[yetijeff]

If the injector o-rings were bad you would probably have a leak and smell gas. Have u taken the intake or tb off lately? Maybe a vac leak

[OrangeVirus1]

injector o rings will never affect compression.

Wasn't referring to compression, was to jumpy idle though
