I was doing a check up on my car today and I noticed my vacuum houses running from my catch can are collapsing. I've never seen this happen before should I be worried or do I just need to use a stronger hose

Did you use heater hose? You should use fuel/oil rated hoses for your catch can.

I believe it is heater hose but if not where else should I check

Yeah that's weak heater use. Use a thicker hose!

Advance auto sells the fuel rated / vacuum rated hoses. Just take your car to em and have em come out and measure it and buy it, they sell it by the inch i believe.... Its how I rerouted my PCV for the blower... Though I am considering going to breathers

I appreciate the help.. I was thinking breathers too but wasn't sure what effects it would have. What's having you consider breathers other then preventing oil from entering the intake

Opens up the PCV system and allows the crank case pressure out as well.

Mine does the same thing. It's do for replacement and changing to the correct hose.

If you have a boost gauge it should give you vacuum too. Mines measures around 20-23 in vacuum at idle IIRC.

thanks fellas I had to travel a bit cause auto zone nor advanced had it but all is well now. Yea Simon it had me nervous for a sec but my gauge reads 23-25 usually

I'll look at mine again just to see but that sounds correct.
