An alternative to the IC O-ring

[audiman]

Fair one Glen, but when you have the advantage of paying trade prices that IC mod isn't very expensive

Especially when you put it on the old mans company Credit Card!!! Ha ha ha.

I call it a perk of the job, he calls it piss taking!!! LOL

[Glen Chamberlain]

dead right m8! no such perks for me though! But i would if i could too!

guys guys guys......
The o-ring will always be stronger than a silicone hose!
An o-ring holds 500bars without a problem!
as long as the "seat" has it's correct dimmensions and is clean.

and btw , this thread reminds me about the light bulb history....

Steffen - somehow I don't think Audi used the same exacting tolerances on the infamous intercooler O-ring as you would find normal in 'offshore' applications

Doesn't it bother you that the intercooler O-ring just happens to be exactly the same part as the seal for the thermostat ? :wacked:

I changed mine at the weekend and found the original O-ring to be less than ideal. The 60/70mm hose mod is great peace of mind...

Yeah l've noticed that is it the same o-ring for the termostat.
The dimmensions in the groove is not diffucult to machine correctly, I've just repaired an rs2 IC and I measured the o-ring groove and the diameter on the pipe that goes into it, looked into an o-ring table, and all dimmensions are perfect.
Many are suprised by the slack in a o-ring application, but that is the way the are designed to be

[audiman]

Well, Im no o ring expert but what i do know is that those o rings are *****!
I have replace 3 since running high boost. That mod pipe, is strong and has not broken yet. Last o ring lasted 2 months!! And yes the IC is ok and the pipe is good, and i used a new genuine seal.

agreed, it is complete pants, theres quite a few people on here who've had trouble with it :wacked:

Thanks Glen!

I have had endless problems obtaining a 70 to 60 reducer for this mod. None in South Africa and when I asked Paul N to send one with my Samco hoses, SFS told him there is a 8 week wait!

Luckily, I remembered Glen's post and in desperation I got a 63 mm straight silicon hose for GBP4 today (I hate this american keyboard without a Pound sign ). I struggled a bit to get the hose on the IC but after streching it a bit using my vice grip, I managed to get it on! I am sure it will work just as well as the reducer and as Glen said it is a lot cheaper! Below a pic before fitting the pressure pipe - which will only happen once my SAMCO's arrive - the Courier companies are driving me (and Paul N) to

Glen, do you have an easier way of stretching the hose onto the IC?

Just a quick note to add. Straight 63 mm hose WILL stretch to 70 mm and easily crushed to 60mm. works a treat! and @ £5 for an off cut from a local supplier damm cheap too! (but thats just me! a cheap skate!)

[martinjs]

drop it into some boiling water for a minuite or so.

Forgot to add that I did soak it in boiling water - the other thing that made it easier was when I cut the pipe down to 5cm (which should fit perfectly as in the photo) from the 10cm I had bought - it is easier to stretch a smaller pipe it seems.

di this mod recently and woah!!!!A MUST

[A80Avant]

i would like to ask this.
If you do the intercooler mod,is the O ring still needed to be in there?Do i still have to use one?

Are the 2 metal hoses going into each other by doing this mod,or are they hold on together by the silicone hose only?

Im asking this cause i have just bought the intercooler silicone hose,and i dont know whether i have to order the O ring again from audi or not!
thanks

[Jamo]

[A80Avant]

cheers
