hello,
i took the sump off to find the head of a bolt in the bottom, on investigation i found it came from the oil pump, it holds a spring in the bottom. but its a special bolt with a hole in the middle for oil to drain down, dont have a clue where to get one so i could do with some help please. here are some pictures





thanks for the help,
i will have to post some pictures of my progress on the project.

Sorry only just noticed this, its probably a main dealer only part. Or try and make your own with a bolt and a drill
