Many general aviation piston engines are quite similar to these engines we have in our VWs. I know someone who was ferrying a Beech Bonanza across the north Atlantic in the winter, and the crankcase oil breather froze shut, about an hour out from Canada, over the atlantic.
All the oil then broke through the seal at the front of the engine at the propellor, and well that was that. He ditched it, and got some emergency radio calls out before going for a very cold swim. Got picked up by Canadian SAR, but in pretty bad shape. _________________ 86 Westy Syncro |

WTH, Who knew this darn hose could be that important.
Your anecdote could really REALLY ruin one's day. |

When it came time to replace all brake related items, the vacuum hose from the check valve had obviously been replaced at some point in time.
What led me to believe it was not an original was that it had a copper tube inserted into a regular vacuum hose ,and the original I came to find out had wire strands incorporated in it. |

funny to see this posted, I just finished putting a starter into the 91 and halfway thru the job I dropped the nut for the starter allen bolt underneath the throttle body. After taking the hoses off of the throttle body and the intake from the breather box I found that I had about a 2 inch cut running on the underside of that hose. I was able to put a 3/4 heater hose on it and it worked great. It actually even fixed a mystery problem that has been haunting me for a few weeks. _________________ Pacifist with a gun |

This hose tends to fail on the bottom and cause "hidden" problems. That is why I say one needs to remove every hose and do a visual inspection and suction test when trying to hunt down vacuum leaks. |

Very true, the real sad part is when the problem first started I thought it was a hose that was leaking or drawing air. I went over the hoses and spent alot of time on it making sure I could rule out that problem... Never did find it until now _________________ Pacifist with a gun |

This sounds like really great advice. When I do my SS coolant pipe swap
I have a whole box of new hoses, T's and Tower to put in too. Got every
hose that GW sells from their +10% site to go with the SS pipes. I know
that not every hose is available now, so the ones that I did not get.
I will do the once or twice over on them, hopefully there will not be a
problem. _________________ '15 Audi A3 Quattro

Another option is scrap hydraulic hose. I just picked up what I needed from an industrial hose maker for free. Double wall construction with wire is the way to go for vaccum lines. Even came in a trick green color! _________________ 1985 Westy

After pulling my motor and when I removed this hose it was pinched on one end and cut on the other...it felt like wet bread I know now why the rear main is weeping after being replaced now. |

After seeing a friends' crankcase breather hose looking like it had seen better days.
I finally got around to changing mine, the hose has been sitting patiently waiting
since March to be installed. It actually takes longer to go to a parts store and get
a replacement hose for this fix to be complete. This is just one more thing that
I can check off as been done ubder my watch. Here's some pics of before and after.
My original hose didn't look bad. Nothing cut or collapsing. The OP of this thread
had a single hose where mine is in two pieces, separated by the heating element.
Could the heating elements' placement in later years save ones main seal?
I think it would be very had for these original hoses to collapse on mine where the
hose is so short from one fittinf to the next. However the eariler years' hose looks
like it has a better chance to collapse as there's a longer run to the heating element.
Must be a reason why VW changed the way the heating element was incorporated.

Possibly related question: why does van-cafe include hose clamps when the stock install doesn't appear to use them, nor did the recent pics of Timwhy's work? Is theirs a bit oversized so as to require them? |

Does anyone know exactly what hose VC is selling for the job?
Type and size? |
Can't tell you on the size without going out and pulling it off the van. The type: It appears to be a regular rubber hose (fuel? coolant?) you can buy at your local auto parts store; nothing really special to my untrained eyes.

It actually fits just dandy. I put the clamps on mine because I didn't want extra clamps floating around (better to be right there in the engine bay, no? ), and I figured since they included them, why not put 'em on? _________________ ~Kamz

How thick would you say that hose is compared to the original? That coolant
hose that I replaced mine with is really rigid compared to the original, and there's
not alot of give to it. Though I didn't need a heat gun to get my new hoses on,
I don't think that they need clamps to keep them on either. I love VC but I think
that once you add up cost of hose and shipping, you can pick up one locally cheaper. _________________ '15 Audi A3 Quattro

$1.62 for a foot of 3/4 heater hose. No clamps required.
Luckily Tim noticed the hose in a picture on another post and now it's good for awhile.
Gowesty sells it for $19.99. If anyone wants me to send them a piece of heater hose for the repair I can do it for $17.99 plus shipping...hehe.

My concern is that oil and rubber sometimes don't like each other very much. I have seen petroleum products degrade (to the point of catastrophic failure) a rubber gasket within a week. Since this hose is related to the oil system, I am concerned with compatibility in the type of rubber the hose is made from. Is heater hose rated for oil contact? _________________ -- 1987 Westfalia automatic (Captain Vino) |

GW doesn't use heater hose, they use stuff that is speced correctly for the task.
Not to say heater hose wouldn't work for a little bit, but lets not compare apples to oranges, as the saying goes.
I am curious about how the silicone hose would work though... |

Wildthings speaks not with fork tongue....silicone hose is perfect for this application. Ive had a piece on my oil breather tower for a few years now and it looks as good today as the day it was installed. Once every few months Ill remove it and inspect it inside and out and it still looks brand new |
