Your PSA for the day:
About half of the engines we rebuild that have had the timing belt / water pump replaced are missing the gaskets that are inserted into the timing belt covers from the factory. These rubber seals prevent dirt, water, and other contaminants from getting into the timing belt area. These are captivated by the covers, and cannot "fall out" unless the timing belt covers are removed. They do take a little finesse to install on older cars since the rubber tends shrink with age and seem to be often left out during this service.
The seals most often neglected are part numbers 5, 6, 7, 8 & 9 on this diagram. As you can see, they are expensive little gaskets.
If you have your timing belt / water pump replaced, please make sure that your technician is installing or replacing these seals as they serve a vital function.
Cheers,

The dealer that had done the timing belt job 7 years prior could not be bothered to put them back in! Needless to say, there was a lot of dirt behind the timing belt covers. The dealer also could not be bothered with changing the pesky water pump, which was paid for by the owner.
