Hi Mike,
The seal journal was throughly cleaned with paint pre wipe, and a wire woll soaked in WD40.
I believe the seals are a different construction, the correct one fitted by Audi to my 3.7 had a forward facing lip, possibly for spacing purposes, or possibly to increase the amount of sealing force, I'm currently unsure which is the intended purpose, but the new seal did not have this facial lip, I am intending to re commence battle on Monday morning, as I now have the non standard seals in my possesion.
I shall report back post operation, I have , incidentally machined up a 38 diameter spigot, and tried the new seal over it, the fit is cosiderably improved when compared to the original item, with the sealing edges and garter springs expanding far more than on the original item.
Best regards,
Steve
