oil return tubes on 2.0 six, changed to: not stock, so what do I have? Options

[fixer34]

So while I'm doing my oil line/check valve adventure (almost done-other thread updates to follow..) and have one HE off already, I'm looking at the oil return tubes and thinking that may be part of the leaking issue. I'm able to turn them and it appears they will pop out without too much effort. There is a large spring that seems to be expanding the tube. It looks like I can just compress it and pull the end away from the case, then pull it out of the cylinder head.
Is it really that easy? I looked on the Pelican site and they talk about using vice grips to squash/compress the tube and then get an expandable one to replace it. Are 911 engines different?
I'm assuming there are rubber seals/o-rings on the ends of the tubes that should be replaced? I looked on 914Rubber and didn't see anything. I found some on Pelican, but almost $10 each, and there are 2 per tube. Any alternatives?

I too have never seen that type used before,on a VW T1 yes but not on a 911 motor,if you can turn them thats most likely your leaks.
I used the alloy external spring type on a T1 1600 and they worked well,they were used when I got them so I replaced the internal "o' rings which turned out to be an odd size,ended up getting them from a hydraulic repair company.

I just tried turning them to be sure they weren't stuck. Maybe an O ring on each end, possibly cracked at this point. Still thinking I don't want to mess with them right now so I can get back on the road for a little bit.
