This is my first post, the throttle spindle seal on the Tdi Injection pump is leaking Diesel, where can you get a new shaft and the brass bush from to do the repair, it’s on a Discovery 200 DTI J Rej, I have got all the info on how to do the job, it’s just the replacement parts that I want, everywhere that I have tried won’t sell the parts I need or don’t have them.
