BOV & CRV hose +troubleshooting

It's worse than I imagined. Everything rubber or plastic on the hot side of the engine is toast or soon-to-be toast. I could cut you with a shard of my bov hose.

I need a quality replacement hose for the BOV and CRV. Will someone post up a good link or tell me what size and grade hose I need, if not stock?

Also, I'm pretty sure my BOV is junk, because I can pick it up and blow through it. Will someone show/tell/link me about testing the stock CRV/BOV?

Save me, Mahjik!

I'd highly recommend just getting the stock pieces from Ray at Malloy Mazda. None of the generic parts store stuff has held up nearly as well as the stock rubber. It gets brittle very fast.

whoa whoa whoa
dont be buying all these parts new
people throw away the stock intake stuff all the time or build plastic sand castles out of them
check the for sale section first
go ahead and buy new hoses though

it is perfectly normal for everything above the twin turbos to be hard and cracking
do you know if this is the first time the turbos have been removed?

your bov being damage might be related to another problem
has the precat been removed from your car yet? that is the first thing that needs to go

The BOV's should be open when vacuum is applied. They should be closed when no vacuum is present.

Buy new hoses from Mazda. If you opt for another BOV or CRV, buy those used.

+1 to new Mazda hoses. I haven't found an aftermarket replacement that works as well, and really after 100,000 miles and 15+ years on the road even aftermarket stuff would probably be crappy and due for replacement.

New hoses will stay nice for a LONG time too. If you want to give your hoses on the hot side better long life get your downpipe ceramic coated.
