312 diesel (closed)
Does this part actually do anything useful? Can it not just be replaced with a piece of silicone turbo hose and eliminate a potential source of failure?
You may very well get another opinion (imagine different opinions of the same Forum) , but I have read just about all the postings on all the Forums and I have conclude that the Turbo Resonator does nothing useful. Indeed the Riordan resonator replacement is merely an aluminum tube machined to fit in place of the OEM deice. A piece of the right kind of hose would no doubt work about as well, however, the Riordan aluminum-tube replacement is nifty because it has a support bracket built in at exactly the right place. Trouble is, it cost around $100 .Does this part actually do anything useful? Can it not just be replaced with a piece of silicone turbo hose and eliminate a potential source of failure?
Howdy,The pressure in the resonator is too high for duct tape or any other tape to hold (25 to 35 PSI and higher).
The reason I would not re-glue or JB weld a resonator is because there is a chance that pieces of the JB weld or glue could get into the system when you back off the gas and I asbolutly would avoid tiny metal parts like screws being inserted anywhere near a turbo intake.
I talked to Claudio the Sprinter tech about this years ago and he said carry a spare resonator OR use a straight alum pipe - (with no parts that can come off like the Riordon Eliminator). I had Claudio inspect the Riorden Eliminator carfully before he gave it his approval to be used on BULBASOR.
I am right now running the Q5 because I have just been too lazy to put the straight pipe back on after Claudio replaced my Q4. It ain't broke, so I guess I'll just leave it onthere for now.
Yeah guys, I really do not know what the type of measurment is on the MAP all i know is that the value is important and I think if you are talking pressure I just assumed PSI but I really don't know because it does not say on the scan guage what MAP is except Manifold Air Pressure.
That could mean anything: I could be like the Richter scale - gets less and less or more and more based on values, who knows? But, if it's an absolute value - then it's DOUBLEING itself every three seconds that your accelerating and I don't know if the starting point is one atmospher or .5 PSI but if it DOUBLES it's getting into some real pressure real fast. I really don't think we are talking about any kind of extreamly dangerous or powerful pressures here because the rubber hose connection to the resonator is after all only a big radiator hose!
How much pressure can a radiator hose take? Quite a lot. Boiling water reaches what PSI??? You can just figure. All I'm saying is that the "radiator" hose, and turbo and Manifold are all very strong compared to the plastic resonator - so it's an easy guess that the resonator was DESIGNED as the 'weak link' in the entire system!
You don't need an engineering degree to figure that out.
The real questions is: Why? and are we defeating another issue by eliminating it?
Nope, the 312 doesn't have one. Looks to me like it's intended as a silencer. Perhaps it is something it was felt was necessary to refine the product? In Europe the Sprinter is hardly ever used as a family vehicle. It is mostly used commercially, or you see them converted into full blown campers or buses. Very rarely would you see a family that owns a panel van with seats privately.That's what makes the whole thing so disturbing for so many people in the US. (Why is it there?)
They don't have them on the Austrailian Sprinters, and your 312 does not have one, right?
So why bother?
Howdy Tim,1 atmosphere = 14.7 psi = 29.92 inches Hg = 760 mm Hg and so on. 20 inches would be 9.8 psi - I'm no turbo expert either but since 9.8 is below atmospheric pressure I suspect it is figured as added boost over ambient pressure.
I suspect if the internal pressures were really high they wouldn't make the turbo resonator out of plastic. Going with what Bulbasor said, I suspect that the higher the average power you are demanding from the engine the more likelihood of weakening the seal within the resonator.
2004-2006 have resonators. Q5 is the latest. I had a Q4 for a long time and it never failed on me. I have a Q5 installed and a Q4 as a spare.Ok, so I'm confused...
Which year T1N's have resonator?
Which resonator is bad?
I have not heard of anyone doing it.Has anyone tried fiber-glassing the outside of resonator before it failed. Would this strengthen the joint and keep it from failing? I have an 04 and still on the original resonator.
Hi there Sikwan, long time no chat.2004-2006 have resonators. Q5 is the latest. I had a Q4 for a long time and it never failed on me. I have a Q5 installed and a Q4 as a spare.
I have not heard of anyone doing it.
