An old man brought me my first Blue Streak.

I do remember that. Try some pb blaster. That stuff works well. You can also try a little heat after the soak that might help loosen things up.

It's been sitting with PB now for 14hrs and still nothing. I think I'm going to do the same thing like with the bolt lug screw. Get a bolt and nut and put it on my impact drill and see if I can pursuade it to move.

Got that filthy jerk out. I put the tool in a vise and rotated rifle. Success!! It was disgusting with a lot of debris in the gunk. I'm sure this didn't help with the leak issue.
    Few more differences in parts as you can see the check valve on this is a pad with a rubber button. This ones valve only has 2 ports and slightly shorter. The valve stem doesn't have the extension where hammer strikes it. Valve spring is pointed and had 2 washers that where corroded together. Check valve spring is copper.
    Ok so I was leaking air out the barrel. Does that mean it was either my valve stem o-ring or rubber valve gasket (valve nut ring was lead)? So I got it all soaking with SS. I think the leak was being caused at the valve stem o-ring. The indent in that o-ring and the ring on the valve body where just making contact. Where years ago the indent wasn't in the o-ring, and it actually sealed. Does this sound about right?? Though the rubber valve gasket didn't look to shabby either. Was flat, not sure if it use to be?

LOVE there rocker rifles!!  I'm trying to buy my first SILVER as we speak! (I have four Blues. )

I rebuilt one.... not for me. I have new found respect for those with the patience to accomplish it! 

Good luck on yours!  It looks real good and will be a shooter again for sure! Be sure you order some secrete sauce from MAC1 too. Its a "requirement" for all Benjis and Dans!

That was pretty nasty inside for sure.  The internals look the same as the benji 317 I rebuilt.  Looks like the lead seals are in good shape so you might get lucky with them.

The joy of being almost entirely all brass. Instead of having to use 300 pieces of paper towel on a dowel you can use 50. If you give the rifle a good hosing down.
   I swapped out the valve stem with the extra I had. I had gutted out the old o-ring at the base and installed a small o-ring from the hardware store.
   I test tried the extra valve, but it wouldn't fit. It wouldn't allow the valve nut to tighten. The moment I tried the factory valve everything went in easily.
  The factory gasket I replaced with an o-ring. I reused the lead gasket, that the valve nut tightens on.
I reused the factory check valve I thought it looked pretty good.
   I reused the factory pump cup. Other then it being caked with sludge it was very soft and in great shape. Can't believe how much crude was in the cup.
  Ok so it fired a couple times everything was a success. Then I came back to it after I did a shoot sesh with another rifle. I fired the stored shot, sounded funny. Pumped up to 3 and fired, sounded weird. Now I'm pumping and air is coming straight out the barrel. Not leaking it's just pushing right out. Check valve?

Try cocking it before pumping. The exhaust valve lets the air out of the barrel.

[bgmcgee]

I would try cocking it first too. You could still have something stuck between the exhaust valve and seat.

[Rob112o]

Yea I don't know what it was. After going back down again later last night. I pumped it several times and after a few it started holding. So it must have been something clogging it up. Maybe one of those 50 pieces of paper towel ripped off a little. So alls good in the hood.

[bgmcgee]

Good to hear.
