2.1 DJ Camshaft

Are these available anywhere?

Probably not. I have a spare taken to 0.5mm under size if you want some photos? Getting shells for it is limited too.
Silverbullet may have one?
Have you a photo of your one?

There are options out there but not cheap

Don't know what GoWesty offer as I can't be arsed wading through their completely "pooh" website, but they must have something as they build engines and sell kits and bearings, likely to be from the far east

I have one new/repro standard 2.1 cam left. It is on a 3-bolt type 1 blank as they all are so timing it is a challenge for the home builder.
Last enquiry I made to Newmans as they they are struggling to get cam blanks for flat 4's and there is only 1 manufacturer/trade supplier and they are out East.

I did consider making a fresh pattern for wbx applications but the demand is too low to be profitable and I have other fish to fry.

I know someone who had an issue with a cam from GoWesty last year, which basically ate the lobes, every 1000km it became increasingly tappety, adjusted preload on the valves, eventually engine self destructed. Destroyed cam returned to GoWesty didn't admit any liabilty, and no replacements available for 6 months and then they became available again, at full price thank you very much, so guess they weren't properly hardened, just a fyi

VW used a type of hardenable iron for cams, once the hard layer has worn through they wear rapidly. Sounds like they were regrinding old cams and assuming that they were hard right through or at least very deep hardened like old Jaguar XK cams which were chill cast iron and never wear.
