Vacuum Lines

[dannmarr]

Go to Subaruparts.com, and go under engine, you will have a whole list of engine parts including hoses with numbers.

Thank you, that worked very well

hmm... didn't have a problem (that I know of) with the auto store hoses that I used - maybe it's time I checked under there again - its been a few years.

Off the topic a bit, but what kinda symptom do you see when those vacuum hoses are bad..?

I started with a code for the O2 sensors, and changed the spark plugs and now it's just the old symptom of code 34 and rough starting sometimes. You might also have a lot of engine shaking when missing one (happened to my legacy)

If you've never replaced them, they are most likely bad. Those things shatter like cheap wine glasses if you poke at them. Remove the intake and they will surely snap.

Some of the Subaru hoses are preformed and hardened. This prevents kinks and withstands the heat from the engine.

Are you talking about vaccuum lines, or pre-formed hoses? In my 30+years of driving I've never known of generic vacuum line to crack within a few months, or years, for that matter. That stuff you got must have been of very poor quality.

If you need a pre-formed hose(s) like the crankcase ventilation hoses pictured above Subaru is probably the only source. For generic vacuum lines, ATF hose and such, I'd bet the quality of aftermarket goods equals or exceeds what comes from a dealership.

I replaced both hoses from the PCV connection, the small hose that connects to the shift kit and the short L hose under the snorkel part. They all cracked at the connections. You may be right about the cheap quality. But I'm not taking chances again, unless it's a temporary fix untill I order Subaru parts. The prices won't break me. Anyway, I sure don't want to replace the PCV hose that goes under the manifold again, what a PIA!!!!

I'd like to know the reasoning behind the location of the PCV valve on these cars. Seems to me they could have put one in each of the valve-train breathers. No, wait... then they'd be too easy to clean or replace.
