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? |

QUOTE(fixer34 @ Sep 2 2020, 01:14 PM)  .. To my mind, a spring loaded assembly like this would be better than a rigid tube. .. (IMG:style_emoticons/default/agree.gif) , how can this not be better than no spring at all, at least for after market? I've seen 'em before too.. but maybe it was type I, not sure. Do we know for sure that Type I's have different dimensions? I might be interested in getting some. . |

The spring is on the inside of the replacement 911 return tube to compress it into the gap,no other reason,the external spring VW one is designed to compress the cup type (conical ?) seals in the case and heads.. different use but principal is the same to get around engine pulling your engine apart. |
