  Another thread got me thinking about a customer I had some time ago with a 2.0 He thought he was driving around with an exhaust leak. Much effort was put into fixing the problem before it dawned on him that this was more than an exhaust leak. A perfect example of why we hate head gaskets on these engines! This head was toast and went to the scrap pile! And it is another example of the need to do a compression test the minute you develop an exhaust leak. Even if you don't have head gaskets! |

A gasket thats not there, can't fail.. This failure occurs much more frequently with engines that retain the head gaskets..
Hence the VW Bulletin to omit them released in the 80s. |

Leaving that part out diminishes the point you're trying to make. Not that I think your point is wrong .............. The Cap'n |

The head redesign was done to eliminate the head gasket but retain the same deck height, cylinder length and chamber volume as the previous engines that used the gaskets. Either way, the gaskets are a lame excuse for a gasket, if you insist on using a gasket, at least use a substantial material, not folded pieces of aluminum.. I have a box full of these things, no less than 3,000 of them.. if someone wants to pay the shipping they can HAVE them! |
