How fragile are oil pans?

The funny thing is that you're supposed to park further back I think, so karma caught them cheating perhaps. It's not even that far of a walk. Less than a quarter mile. I thought the same thing when I saw the sticker. Unless they're from Germany... but then I don't think "Buy Local" stickers are a huge deal over there like they are here.I'm sure that if possible she would have bought a car built at a plant near the crag. "Buy local" is more of a food/messenger bag/hardware store strategy. "Buy American" is the one about cars. Although Toyota apparently does make some engines and transmissions in West Virginia, according to wikipedia. |

Jetta w/busted oil pan
This happened at Moe's Valley. I seriously thought I would clear the baseball-size rock by a mile. I was obviously wrong. |

If you VW users are serious about your traveling offroad why woudln't you buy a skid plate? Seems like a huge gamble for not a lot of money. . . So much cheaper then dealing with your brokedown ass in the middle of nowhere with a hole in your oil pan. Maybe some people just like to be vulnerable. |

I gotta laugh at all the VW hate.... |

If you're driving off-road in a low-clearance car, and you don't know what your various clearances for the differential, oil pan, whatever... and you whack something..... like I said, not the car's fault!!!!I would have thought so too. But it's clear to me now that VW aluminum oil pans are unusually fragile. |

Surprisingly, I found the Lincoln Town Car, to be very sturdy in off road situations. Even those, where it would be difficult to distinguish the road, from an intersecting arroyo. |

The plastic "skid plates" on cars are splash guards, they keep water and mud out of the engine compartment. No impact protection intended. I ripped them off my Honda in deep snow a few years back with no measurable effect on fuel consumption. |

But I'm sure it doesn't have an aluminum oil pan, or aluminum anything else. |

These have skid plates already fitted: |

Most cars have aluminum oil pans. They are either cast or they are stamped. Some have stamped steel oil pans. |

Would you like to have a BOMBER oil pan? So when you whack it on something, the force, rather than being absorbed by the oil pan (that can be replaced in 10 minutes) gets translated into.... busted engine mounts, tweaked frame, jacked engine/transmission seal.... who knows where that energy would be absorbed...? There's a reason you don't want a bullet-proof oil pan...... |

Engines are mounted low in passenger cars to improve handling and keep the from of the car pleasing. |

Lost the oil pan to my 2005 VW Golf TDI on the road leading into Creek Pasture at Indian Creek. It is a dirt road but it is well maintained and had been in there many times in the Golf. Here's the funny thing. The car was still under factory warranty so I called the number for roadside assistance that was stickered on the back window. They came out and towed me all the way to Glenwood Springs, about 250 miles, because they don't want anyone but suthorized dealers touching their cars while they are under warranty. |

If your concerned, imitate the rally circuit and install an aluminum skid plate to replace the factory plastic one. |

There's a reason you don't want a bullet-proof oil pan......The problem with the oil pan as energy absorbing structure is that it is full of oil. I propose that it's not bomber simply because it normally doesn't need to be. VW clearly effed up by putting their pan a hair too low, making the aluminum a hair too thin, making the front springs and dampers a hair too soft, making their cars a hair too nose-heavy, and being too casual about pre-production road testing on American roads. Google "cracked oil pan"--at least 4 out of 5 instances are VWs. Often from on-road driving. Driver skill, caution, and alertness will play a role in some cases...but even Ayrton Senna had at least one big crash. |

Phil...... spot on. |

The big issue with the TDI oil pan is how low it hangs, the aluminum is a marginal aspect. In stock configuration it's guarded by a rather thin piece of ABS plastic. Solid skid plate solutions are numerous. The optional steel oil pan provides slightly better puncture protection to guard against gravel damage and isn't intended to guard against blunt force impacts. |

get the correct vehicle for what you want to do... if you don't, don't whine when your stuck in the middle of nowhere trying to get a bar on your cell to call someone to drag you out... I guess common sense is out the window these days... |

I also busted the oil pan on a '99 Jetta--hit a speed bump that was really hard to see! |
