  1. Ball and spring in oil filter

    Thanks mantadoc - will do!
  2. Ball and spring in oil filter

    Thanks everyone for your assistance. I have managed to find a replacement timing chain cover via a local Whatsapp group. Looks like quite a big job to swop the part but it looks like most of the gaskets need replacing anyway so will give it crack. No doubt I'll be looking for advice here when I attempt the job!

    Sorry - just to clarify, I think it's the timing chain cover that I need
  4. Oil pump cover/assembly

    Hi all. I'm looking for an oil pump cover/assembly for my 1971 Manta A (the bit that the oil filter screws into). Any advice where to find one would be appreciated. Thanks
  5. Ball and spring in oil filter

    Ok, so took out the pan at the bottom of the car and had a good look and, unbelievably, the collar that would normally hold the ball in place seems to have sheared off in a few places thus allowing the ball to escape. I suppose this means that I need a new cover/assembly. Does anyone know where I may be able to find one?
  6. Ball and spring in oil filter

    Thanks for the comments guys. Just to recap, it may be a bypass valve which has popped out of one of the cavities where the filter screws into the base of the engine? H-400 , you think it may also be a part of the old filter? Just to add to the problem, I have changed the filter and refilled with new oil and I'm getting zero oil pressure and the oil light goes on when starting the engine. I'm obviously too scared to run the engine with no oil pressure but it makes sense that the loss of a pressure relief valve may cause a complete loss of oil pressure? Lastly, in order to get to the bottom of the problem, the first port of call would be to remove the timing cover and see if the ball and spring may have popped out of there?
  7. Hi all, I have a 1971 Opel Manta A When changing the oil filter recently, the old one contained a ball bearing and spring. I assume this is some kind of pressure valve? If so, is it possible to re-fit the bearing and spring or do I have to buy a new oil pump assembly? Any advice would be appreciated.
