Charge Relief/Air Bypass Valve help
 

Hey guys, the 90 degree elbow coming off the back end of my charge relief valve is cracked as well as the hose that runs from the air bypass valve to the y-pipe. I have been looking for a few hours for the specs for these hoses so that I can either (a) replace them with factory hoses or (b) order new and improved hoses.

I have an order that I am ready to place for a 90 Degree 1.00" ID High Temp Silicone Elbow for the CRV fix (Guessing this is correct), but I have not been able to find a suitable hose replacement for the ABV. Can anyone please help me.

Also, In this order I've got (3) 3" straight silicon straight sections to replace the factory ones on y-pipe, intake, etc... (Are the 3" OD the correct size or are?)

why not just take the hoses that your replacing to autozone and get them...

Tried that and they cannot help me... Same for AAP too..

Is it just a rubber hose, or something more specialized? The problem is that I cannot seem to find any specs on the part other than its part #.

What you can use is heater hose. Go to Autozone or NAPA and ask to browse their pre-formed heater hoses. Pick a hose which has one or more 90 bends in it as well as some straight hose. You can then cut them to fit for your BOV hoses.

its just a hose... Just get something with same diameter, cut, put it on

Thank you very much sir!

Heater hose won't make the 90 degree bend off the y pipe without kinking. You are going to have to find something that has a bend in it and cut to length.

Unless you buy pre-formed OEM heater hose from another car which has a pre-formed 90 degree bend. Been there done that.

Or just order it up from Ray Crowe and not have to replace it again in 6 months when the heater hose hardens like a rock. Been there done that. :)

Yep, get the OEM part. They're not perfect, but they last a really long time. They'll also last much longer if you don't have the stock precat and have a ceramic coated downpipe. The precat just bakes those hoses like crazy.

They're not too pricey new either.

And you are sure you had "heater hose" and not just some pre-formed rubber hose? I've had heater hose on that spot since 2003 without any issues.

Yes. It didn't become an issue until I had to remove those parts and their corresponding hoses when I was testing a boost creep issue. Then I noticed how hard it was and the hardened hose cracked during R&R. I don't remember how long it was actually on.

Not all hoses--heater or otherwise--are created equal. Probably the luck of the draw with respect to the type of rubber compound used on various manufacturers' hoses; some will be more resistant to the presence of oil than others.

^^ exactly. If you get a random heater hose off the shelf you aren't aware of what the rubber content is. Some hoses will handle heat far better than others.

Really, at the end of the day, just get the stock hoses. No reason not to. They don't cost much, they fit perfect, and they will hold up a VERY long time. Considering your hoses are most likely the stock ORIGINAL hoses and now, 15 years later, they're failing, I think they did a great job. To paraphrase Yoda, "when you get this age, look good you will not."

I replaced mine within the first year of owning my FD (about 2005 or so) and mine are still soft, easy to remove and reinstall, and hold boost perfectly.
