Huh. Down the centre of each lobe starting about half way to the point, there is a weld mark, it goes from the Grau of the cast to like a brass color weld ten back to cast.

that is how they reground it. They take the base circle and ramp angles down to make it performance. I would guess that is just the machining, not weld.

I never noticed anything different visually with the cams that I saw. Can you post pics?

That's not a machining mark at all.

Not entirely machining mark, but I think you are correct it was welded then machined off. I would guess it was a fix of a flakey hydro cam. Those things seemed to always have some metal flakes coming off of them.

Was told its a dr d cam but there's no proof. There is no way to tell eh?

You could measure the base circle of it and a normal hydro cam and if the one is smaller that is probably the case.

around the central axis the cam would rotate (the big lobe) was smaller and over all height from point to base was about the same, touch taller but nothing major. this was is comparison to a 1.9 idi cam i had laying around. sound right to be a dr. d cam?

I would think so, not for sure, you could ask burn your money or Giles email. They should know for sure.

I don't know. A smaller base circle is how regrinds are done. Without exact measurements I don't think there is anyway to know for sure who made this cam. I don't have the specs anymore so I'm of no real help.

Your Dr. diesel cam was pulled from a built little 1.6NA mk2 golf. It was white with green interior if that rings a bell... Im 100% sure it was a dr. diesel cam. I'll find out who built the engine and you can talk to him yourself through Customobsessions.
I have another performance cam sitting here if youd like to compare. Although im not sure who did the regrind. Youd have to ask Chris Russell that question as it came from the race Rocco I bought and parted out.

Any thoughts about using these cams in a 1Z/AHU TDI? I've seen some folks talking about AAZ cams being a bit better than the TDI ones, if that's the case would these be better still?
