Blown PDS shock?
(Click here to view the original thread with full colors/images)

Well after hearing strange sounds coming from my shock(sounds like air in there), I took the spring off and decided to let a little nitrogen off to check if there was an abundance of nitrogen or very little (the shock is going back to my suspension tuner anyway) What came out was oil...mixed with gas...
Is this the definition of "blown"?
And is air in the shock(not bled correctly) the probable cause of this?
Thanks for any insight

Yours has just lost the seal between the nitrogen and the oil-its just a simple O ring.If you have air in the shock as well, i would look to another shock builder.Neither of these things should happen after a service.

Marcus - you are not answering my questions,
could air be the cause of this?
Is this the definition of a blown shock?
I don't know if there is air in there...Iam trying to surmise what happened

I doubt air would cause it-more likely the air(noise you heard) is the nitrogen thats seeped into the oil side.
A definition of a blown shock doesnt really exist-its just a widely used term for a lot of shock problems-most likely when someone has seen a shock puke all the oil past the seals they say its blown.Like a blown engine in indy cars.
It sounds like a simple case of the N2 seal failing to me.They do get dry sometimes and so will fail.
