Oil Pump

As the oil leaks could be the result of a pressurisation of the engine block, perhaps due to a blocked pressure relief valve, blocked filter screen, or just a gummed up pump, Ithought it would be prudent to have a look at the oil pump. Not the easiest task with the engine still in the vehicle and no lift, but actually quite do-able.

With the sump off, the first discovery was a part of the timing chain adjuster lying in the bottom. And so, deciding to check the oil pump turned out to be a good idea, as it revealed a potential problem elsewhere. A check of the timing aparatus is now in order. This will be the task once the oil pump is checked and re-installed.

Below, a view of the sump interior, after a cleanup, still in its factory black paint. I don't know where the two scratches came from, perhaps they're connected with the timing chain adjuster part.

The part found in the sump:

All pump parts present and accounted for, and in good shape, with very little wear apparent. Gears are within tolerances.

Just a view of some of the markings on the pump's lower casting.
