C20let oil return thread size

Can anyone tell me off the top of there head what size thread the block is for the oil return . I need an adapter to an10 . I did have one but cut it up like an idiot as i needed a an10 thread to weld onto somthing . Now i need this fitting again for new turbo . Cheers

I think all the oil gallery bungs are M14x1.5. From memory mate

I know the rear one for the feed is thats size for deffo . Im pritty sure the front one was a tapered thread though . I could be wrong

1/2" bsp for anyone in the future
