When you get the collapsible tubes do not go for the aluminium types.
then get your self Sachs lubricant from Pelican parts.It is the best now days, it used to be Bosh-which is NLA.
In assembly, lube the inner 2 o rings well and try to slide the tubes with your hands if they move freely.Then put the c clip on then the female type tube which will stop on the clip.
When you are putting the tubes together make them long enough so they fit nicely in the space not to short not to long, then adjust the c clip .Try one before you assemble the others.
Make sure the part of the tube where the 2 o rings are go away from the exhaust.So towards the middle engine case.
In assembly insert the longer side to the camshaft housing and pull back the smaller side towards the engine case , you can help your self with a flat screwdriver on the lip of the smaller tube.then you use the pliers to slide clip to the space for it.i use the pliers trough the heat exchanger for an easy access.or if you get pliers with bend tips, it will for from the bottom of the engine.

I hope this helps

it takes me 20 min ,so one hour should do..oh yaa drain the engine case only before you do this.

My 3.2 had aluminum tubes 4 pieces for each tube, the o rings were shot and the ends came off the tubes when i removed them, I jb welded them back together and got new orings. I will replace them with the steel ones because they are starting to leak again. Silicone grease works good to make them slide. No heat exchanger removal neccesary it is just a bit harder on the left side. My first repair lasted about 3 years.

Lube definitely will help. I have done this many times prior to my build.

You don't need braun but as in all of our Porsche tasks, the proper tools or improvise the tools. Get two BFS's and equally pry the leaking offenders off after removal of the circlips, use electrical tape if you worry about marring the case of tubes then get some matching pry bars and two clamps the same ID as the OD of the tubes. Place the clamps where they need to be so the pry bars can press out and the tubes into the case and heads. I swear they will simply plop right in. Leak Free. Don't forget the circlip





Removing the Heat Exchangers makes it even easier.

I pushed the case side in first, then used a giant pair of channel locks to pull the other end into the head. With the Dow 111, pops right in,
No scratches....

I took my exhaust off and put two hose clamps on the tubes. I than used two small crowbars to expaned the tube. No scratsching here

^^^Easy-peeezy with the exhaust removed. My comments were made to assist sugarwood with his decision based on his exhaust being on the car (as he wrote he has rusty studs). I don't know how much room B&B headers offer, but if it's anything like a stock heat exchanger it's a tight fit.

Tube quality. Aluminum tubes are not the cat's meow because they are made from pieces that are assembled with epoxy. At my shop we preferred the tubes sold at Porsche, where each section is a single, formed, piece. Anytime I can use a replacement part that has fewer opportunities to fail that's the part for me.

Heh heh

I like sugarwood. He is a righteous dude.

Leghorn award presented for valve lash. Upgraded to the rare Darth Leghorn award for actually attempting to remove his exhaust in a subsequent effort.
