Posted: Sat Nov 19, 2011 1:42 pm Post subject: Oil Sling Arm? |
|
|
So I took my bus to a Mech and he told me that my engine was missing an oil sling arm. What the heck is an Oil sling arm, where does it go and how can I find one?
I googled and searched in the forum threads and couldn't find anything!
It is making a fine spray of oil on the back of my bus. |

he is pulling your leg. Maybe he was thinking you needed a huge wiper arm on the back to sling the oil off. Take some photos of your engine and under the engine from behind and post them here. Then we can see what is going on. Make sure the engine photos are lit and that it isn't all dark in there. _________________ “Most people don’t know what they’re doing, and a lot of them are really good at it.” - George Carlin |

What engine do you have and how badly is it leaking oil? Need to cleaner her up well and find out where the oil is coming from. |

What kind of bus and what kind of engine? And what kind of mechanic? _________________ 71 Superbug

Lawnmower mechanic It's been a looooong time but I seem to recall that the B&S horizontal shaft engines had an oil slinger for lubrication on the conrod. _________________ Vehicle: 1975 Special order delivery walkthrough panel based pop-top camper (LCA / Sunliner).

Could he mean the oil slinger on the nose of the crankshaft?

Oil slinger is usually found in low oil pressure motors. The oil slings off the ring to lubricate the timing chain, fuel pump (if it's mechanical) and main bearings and/or seals.
I'd look for a different mechanic, like yesterday. Obviously the VWAC flat four is not something this guy has torn into, or has basic knowledge of the internals.
Sounds like you need a hub seal, or possibly oil cooler seals - both are common to fail and somewhat easy to replace. Find a local indie VW or euro shop and see if they can do the repair. _________________ -Mike

agreed, but an oil slinger arm is a very specific thing. Arm being the operative term. It was either a "VW's are lawnmowers hurr" joke or this mech actually believed it. Or if he's anything like me the wrong words came out and made him look silly. _________________ Vehicle: 1975 Special order delivery walkthrough panel based pop-top camper (LCA / Sunliner).

maybe he meant oil slingar mmm. As in a type 1 motor oil slinger. Type 4 motors don't have an oil slinger. Type 1 do. It is a cupped washer that keeps oil from coming out the crankshaft end. _________________ “Most people don’t know what they’re doing, and a lot of them are really good at it.” - George Carlin |

Well, I learned, or possibly re-learned something there. Never had to touch the bottom end of a type 4 thankfully. _________________ Vehicle: 1975 Special order delivery walkthrough panel based pop-top camper (LCA / Sunliner). Motor: Nippon 1.8L Single port Wasserboxer, Transmission: 3 rib 002. |

Kind of interssting but Tom Wilson forgot to mention the oil slinger on T-1's. I think he did it on purpose. To let people know that when they tear their engine apart again they need to learn how important it is to pay attention to every aspect of engine building.
Oil slingers were used on some old engines and also small engine that don't have oil pumps. _________________ 71 Superbug

I would think that the mechanic meant the oil slinger as well, assuming he is talking about a T1 engine and not a Type 4. Of course he may not know the difference between the two. Assuming the problem is oil leaking out from around the crankshaft on a Type 1 then the problem is probably not the slinger, but oil foaming, high oil level, or something wrong with the crankcase ventilation, as slingers don't wear or disappear suddenly.
Without more info, at least knowing what kind of engine and some general idea of its condition we can only make very wild guesses as to what is wrong. |

correct - oil blowing out to me means blowby and worn rings. It can also be a drip under the car swirling behind it or even a trans going dry. _________________ “Most people don’t know what they’re doing, and a lot of them are really good at it.” - George Carlin |

Would seem to me that if the oil slinger washer were missing, the pulley would go on to the crank too far, and bind against the outside of the case? _________________ '71 panel, now with FI

He didn't ask for any money cause he didn't fix it but he gave me a free tune up. He might have said oil slinger. I'll have to give him a call. I think it is a low pressure engine cause it came out of a bug. I wasn't able to get a hold of him today so i'll try again later.
Also the tins for my engine don't fit correctly so that's another thing I have to take care of. Sorry for not bringing pics yet but they will come. |

I left one out of a 1600 due to some distracting guests in the workshop once (you know, the person with all the time in the world usually spends it with someone who can't spare a minute) with no pulley fit issues after, infact 11 years and counting as a daily driver and still no leaks. _________________ Rust NEVER sleeps and stock never goes out of style.

The slinger has nothing to do with oil pressure, it is just an earlier technology for keeping the oil mostly within the crankcase. Early seals made for rawhide and other materials were not all the good and even later once rubbers and plastics became available, an oil slinger could in the right circumstances give comparably performance which would not deteriorate with time. |

before i rebuilt my 1600, it would spray tiny dots of oil on the back of the bus and inside the engine bay. seemed on and off.
case was disorted, causing low pressure when engine was hot, but i dont know how this would cause oil spraying outside the case...
but i drove that engine thousands of miles like that. |

Low oil pressure has nothing to do with it except for usually being associated with a worn out engine with lots of blow by.
Mine had a silly little leak problem behind the pulley. Not all pulleys have the same depth of spiral groove so I changed pulleys again and the minor leak continued. So I put in a sand seal. But while doing the seal mod I ran it without the crank pulley and found an impossible to see leak in a weld in my custom pump cover. It was spraying onto the back side of the pulley. The very first thought was the chance of forgetting the slinger. _________________ 71 Superbug
