Air is blowing through my oil cap when i open it while idling...Would this mean that my rings are shot/f*cked? Doing a compression test in a little bit when my dad gets home, so i guess that will let me know, but i'm just wanting to know ahead of time...

 

No

 

Is there a lot of air? Do this, while it's idling, take out your oil dip stick and if exhaust smokes come out, then your rings or ringlands are dead

there should be smoke.. out the oil cap or breather valve.. but do a compression test even if theres no smoke.. better to see signs that way before it blows up..

 

ok well i did the compression test and here's what i got...

from passenger side to driver side
165, 160, 180, 160

When i went to take the spark plugs out i noticed the far right one on the drivers side was loose...so i thought that was the cause of the air coming out of the oil cap, but after i did everything, there's still air coming out of it...

anyone have any ideas?

the loose plug wouldnt cause the air. was the motor cold/warm/or hot when you did the compression test? those numbers seem low...what motor is this?

 

the motor was warm...its on a d16z6...people from the EG forum said it was normal for the air blowing out of the oil cap? /

 

combustion chamber leakage is normal (crankcase pressure) you can always do a compression and leakdown test to see how much leakage there is, and determine if there is in fact a problem.

 

is there a how-to on how to do a leak down test? never done that before...

just checked my PCV valve and its still fine...i can still hear it making the clicking sound when i shake it...i just cleaned it up a bit and theres only a little bit of air coming from the cap...that normal?

There is always going to be a little crankcase pressure even at idle. Now if it is smokin bad out the crankcase breather then you probably have a problem. run the compression test once more, your numbers do seem a little low make sure you crank the engine over several times then I usually stop and crank a few more after that

 

whats a good compression for a d16z6 with 0ver 180k miles?
