You seem to be all over the board. changing the subject constantly to shift the argument. You also have a thread where you argue to the death that these hoses dont leak...
now you are accepting as gospel that they do? which is it?
I have accepted Kuehl's statement that ALL hoses leak, most of them, by design, at a perfectly acceptable rate. The question becomes, has always been, at what pressure level does the legacy hose leakage in our Porsche's become unacceptable.
GTI, Kuehl's, statement seems to indicate that our legacy hose is designed specifically to act as a "pressure relief valve" so as to prevent an "EXTREME PRESSURE " event, EXPLOSIVE event. To this I agree.
It makes no sense, obviously, for our hoses to bleed off at low system pressures, only as pressures approach a design limit specification.
I used my garden "soaker" hose only as an example that this can be done. At 2-3 PSI it only "sweats", but at 30 PSI a LOT of water permeates through the hose.
why dont you test the hoses to see if they do? how hard would that be? rig up a video and test it.
The "proper" test procedure, the one used by DuPont, involved a closed chamber with the "test" hoses inside pressurized with the subject refrigerant. A gas sniffer was then used to measure the level of refrigerant over time within the chamber due to hose leakage.
or are you now on the Kuehl wagon and are now going to change your hoses as he recommends?
The way I see it the GTI statement, possibly written/composed by Kuehl himself, fully validates my theory...our legacy hoses do not leak beyond an acceptable rate, 5-10 years, absent pressure excursions in the range of 350-450 PSI.
Whatever fits your argument of the day is the position you take. For two years you have said they dont leak. stating that Kuel is selling snake oil for saying they do. now you are agreeing with him, saying they do in fact leak.
Kuehl holds the position that ALL hoses leak to some extent, to which I fully agree.
On the more immediate theory... The increase in temp doesnt prove anything because you havent proven that the temp increase of 35 degrees = increases in pressure...
I'll just leave that to your favorite physics textbook...
Or a simple example you could use with a 9 YO, blow up a balloon inside a 78F room and then take it outside into the BRIGHT sunlight at 100F.
and what does that have to do with whether the hoses leak by design or because of the R134a molecules... what is your theory?
My theory is like that garden soaker hose design, it only leaks acceptably provided the pressure inside is appropriate to its design use....
"..the R134a molecules.." Unlike others I am perfectly willing, until evidence indicates otherwise, to accept the statements by the EPA, SAE, and Dupont, that our legacy hoses, permeated with R-12 lubricant, will only leak r134a refrigerant at a perfectly acceptable rate.
So by shooting the video and doing the tests... you will indirectly prove whether the TXV / TEV is closed ... or not...which will allow you to test whether the pressure increase leads to pressures high enough to cause leakage? which will allow you you know whether a spal fan with a trinary switch will impact the underlying problem of refrigerant loss?
and whether that leakage is in fact through hose design or some other mechanism?
Wait..you're no longer taking Kuehl's, GTI's, statements as gospel..? I'm perfectly willing to accept the statement on GTI's site regarding our hoses being designed as "pressure relief valves".
you are dancing... and you arent a very good dancer...
You've been listening to my wife..??
so you in fact have ALOT to prove... Wake up WWEST!
