Capri Oil Pump Leaks

I have been noticing a bit of oil on the garage floor lately & that makes me a bit cranky. That's why last year I pulled the engine out & redid the engine oil seals. Anyway, I thought it was the oil filter as I always have trouble with the filter as the earlier Kent engine has that ridge around the oil pump.

On closer inspection, it wasn't the filter but the outer cover of the oil pump was leaking very slightly. On consulting my trusty big red manual, I found that there was an O ring inside the cover & obviously, that was my problem. Getting the three nuts off to remove the cover was really easy, which is a change for me. Getting out the O ring wasn't too difficult either.
Now, next problem-where can I get an O ring from? I went to a Bearing Store
at Salisbury & the guy was very helpful & found me on he thought was the correct size. Total cost = $2. Went home & tried it & I wasn't really happy with it as I felt it was too loose.

So, back out to Seal Imports at Acacia Ridge where the young guy found one that seemed more suitable and gave it to me free! Yes, free of charge! I thanked him & went back home to have another go with this one. This fit was much better so I bolted the cover back on, hoping that would stop the leak.

Yes, it looks like that has done the trick but I will take it for a longer run on the weekend. Hopefully, the new O ring will have my garage floor clean again.
More on the oil filters later.


Postscript. I have partially solved the leak but created another. It seems that there is just a very minor leak but there is no oil on the floor. If you run your finger under the cover, there is a little oil. However, on re- tensioning the three bolts, one (top left) seemed a little loose so I very gently tried to tighten it & then I thought it had broken off. Every time, I work on the car I am very conscious about breaking studs or bolts so I feared the worse again. Anyway, I removed the bolt & it was intact but there was a bit of metal thread on it so it seems that the thread on the oil pump is damaged. For a temporary fix, I wrapped a few rounds of pink plumber's tape around the bolt & it appears to have held on with a bit of tension but a more permanent fix will be required.
