kevin50 Posted August 20, 2020 Share Posted August 20, 2020 Noticed a leak from under engine every time I parked up. Looked everywhere and finally found it here on Vid. Cant understand how / why it is leaking from there. Any Ideas ? Quote Link to comment Share on other sites More sharing options...
dailysleaze Posted August 20, 2020 Share Posted August 20, 2020 Looks like the head seal. Unfortunately one of the most annoying seals to replace. The pump will have to come off in any case to tackle it Quote Link to comment Share on other sites More sharing options...
Snagger Posted August 22, 2020 Share Posted August 22, 2020 Looks more like the seal between the main case and the square block on the back to me, but it could be running down from the top cover as DS suggests. Try nipping up the rear case and top cover bolts, but if that doesn’t work, you will probably have to remove it for an overhaul. Mike did a video or two showing how to strip and rebuild them on his Brittanica Restorations YouTube videos. I’m not sure doing the full strip and rebuild is prudent unless you have the tools and knowledge, but you might be able to deal with that leak.

dailysleaze Posted August 22, 2020 Share Posted August 22, 2020 Just to confirm, the head seal is the large O ring; as Snagger explained it "the seal between the main case and the square block on the back". I realise the video thumbnail shows the top cover seal, but if you watch the video you'll see where the head (square block on the back) is removed (@ 7:09 timestamp), and it has to be done with the pump pointing down as the springs are likely to fall out Quote Link to comment Share on other sites More sharing options...
kevin50 Posted August 22, 2020 Author Share Posted August 22, 2020 Thanks it is definitely not running from top cover it is completely dry on top. will try giving them a nip up. They are torx heads very difficult to get in. Quote Link to comment Share on other sites More sharing options...

Kevin, that video DS posted is the one to watch. Quote Link to comment Share on other sites More sharing options...
oneandtwo Posted August 29, 2020 Share Posted August 29, 2020 The head seal is dead easy to change, you can do it in situ in a couple of minutes once you have removed the injector pipes. You undo the bolts just enough to expose the O ring and no more, and use two longer bolts to temporarily hold the head in position while new o ring is stretched over the head. These seem to fail if the injector pump is removed and refitted again and you have the old type injector pump support bracket which does not align the pump up in exactly the same place every time.
