Ok, I gassed up my new (to me) Blazer and this is the issue. Air leaks down the barrel and into the chamber. You have to hold the trigger back a little while to make the bolt cycle completely, and the bolt does not come back flush with the body.
Ideas? Is a trip to PPS in its futute, or is this fixable.
This is my first PPS gun. I am not an imbecile, but I have not worked on a gun like this before. help me out.

5-6 drops of oil in asa or airline, and 3 on hammer where visible. Gas up and fire alot. If bolt isn't coming back, INCREASE LPR pressure by tuening the screw in a bit like 1/8 turn inciments until it cocks reliably and bolt goes back to proper position.
See if shooting the heck out of it with oil (clean barrel out later) gets the down the tube leak gone and bolt behaving at proper LPR pressure.
Then go from there.

Sounds like re-cocking issue, adjust the LPR.
Other than that... go through this for full Blazer settings:

Pmi oil will be fine. I don't think you'll have to adjust the timing exactly. The LPR (right side of Blazer) takes an allen wrench and controls the travel of the ram which cocks your Blazer.
If you cock the gun by hand and then air it up does it still vent down the barrel? If it does you may need to send it in for new seals. If it does not, Your velocity spring tension may be too high.

If oiling it up doesn't stop it (reconditioning dry seals) then you'll probably need to either send it to PPS for a rebuild or buy a seal kit from them and give it a go yourself.
I'd send it to them. That way you know it'll be a top shooter when it comes back.

One other possible cause for the leak that nobody's hit yet: what's your inline/high pressure reg set at? If you're trying to run a stock Blazer on like 200 psi, it's probably not going to work too well. Finally, (and I don't think this is the case) make sure you've got enough pressure coming from your tank. I've spent hours troubleshooting some miniscule problem only to find that the tank I've been using was nearly empty. It happens to all of us...
