  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! |

QUOTE See what happens when someone runs 8 month old race gas in an engine with near 13:1 CR on the track.. Its nasty! That was an example of a failure that did not have a head gasket. And it only took about a lap and a half. And no, it was not our race team. We know better than to race with old gas! Failures of this kind are waaaaay more likely to happen with a head gasket, but can happen when no head gasket is used. I have been harping a lot on the need to deck cases when rebuilding engines and I'm going to do it here again, as the uneven cylinder loading caused by warped and sagging case spigots surely increases the chances of head seal failure. |
