Public Service Announcement:
We've all seen it, replaced weeping hose connections, fixed leaks etc. But yesterday I made a more surprising discovery. In the course of pulling apart my engine it turned out that the bolts fixing the brackets for the steering pump, alternator and distributor were all shockingly loose. A couple were just finger tight. It seems that some of the mounting holes penetrate the block and are subject to oil seepage. Ditto the distributor mounting flange, which was also seeping. Some of these bolts are pretty buried and probably hard to reach with engine in the car.
Hopefully I'm the only person with this problem, but I doubt it. So, if you've got messy seepage driving you nuts, this would be a good place to look. And there's also the obvious issue of safety. Cheers,
