oil line thermo to trombone

[78PIECE]

Hey, I have a 78 911 and Ive notice the previous owner had crushed with a jack (like an ass) from the thermostat to trombone. I know I need to be careful with the threads removing the old one from the thermo (got me some BP blaster on it) and maybe some heat. Now the question is and may be a dumb one. But once I pop the new one on there will no oil in that line do I need to do anything to relieve that air? The Bentley manual says nothing about it. Just wanted to check with the Pros. and any tips for removing the "Life Line" of this machine?

Sorry to anyone who saw this in the wrong category, Im still getting used to this site.. and computers.

Nope, oil will flow once the thermostat opens.

Just a note as you mentioned you're new to computers. You've posted twice (no big deal) but it will be confusing. Go to one of the posts and click on the "edit" button. You will get the choice to "delete this post", and you should do so. Since I responded to one of them, you will not be able to delete this thread, but you can delete your text. So hurry, and delete the other post to avoid confusion.

Now to your question. No, you don't need to do anything to get rid of the air in the line. Once the thermostat opens, oil will flow through and push the air into the oil tank. Simply drive the car until the thermostat opens, let the engine idle and check the oil level with the dip stick. If you need to add oil, add just enough to get the level between the two marks, preferably closer to the lower mark.

Do yourself a favor and remove the oil line assembly as a whole unit from the car. It is a lot convenient to work on the oil thermostat and oil lines on a vice or work bench. Even if the car in on a lift, the space is so limited to maneuver the oil wrenches in the rear fender well. Don't worry about the air from the oil line. Concentrate of the nut removal and avoid damaging the threads.

If things go bad, or you cannot get the lines off the thermo, these work. Cut off the old nuts, and use these.

Yep, I just did this over the week end, .... had to change the thermostat but of course one of the lines from the t-stat to the front wouldn't budge so had to take the line and stat out as a unit rocker panel has to come out too which is no fun.
Used a MAP torch and was finally able to remove the line, with no damage to the threads. Then tackle the screw cover on the t -housing itself.

I think with a 36 mm crows foot MAYBE the lines at the t stat from the bottom can be removed with out having to also remove the two to the tank
I recommend checking the function of your t stat once you're in there cause it's not a job one would like to do twice.
