Does anyone know if there are oem Quality Style valve adjusters that can still be purchased? I'm looking for ones like the original that have correct heat treating, not the black ones I've seen on the market.
Thanks in advance! |

| Maybe try BugCity in CT? Dave has lots of stuff you don't find many places. |

| I don't have an answer, but wondering if anyone tried heat treating a set of aftermarket adjusters themselves? |

I rebuilt my 1600cc engine in 2017.
A few months later I noticed this. My adjuster and the adjuster nut were found in the valve cover.
I ordered a new adjuster and a new locknut from an Ebay supplier, and the engine has been fine since, don't know how this happened. That was a factory 1971 engine I rebuilt, and the vehicle has been mine since 1976, so I cannot blame any previous owner.

| I think I will try bug city, if I can't find what I need I think I will just use swivel feet adjusters which I mainly use on most of the engine rebuilds that I do but this is just a stock 1600 engine, when I worked at a VW shop years ago the properly heat treated ones we're ready available but I know they're hard to come by quality ones so if I can't find something I'll just go with swivel feet. |

I prefer to reuse the originals. There are plenty out there with take off stock rocker arms.
I spin them in the lathe, and hit them with a file to knock off any bad spots on the face, and they are usually good to go. The few that are really beat up I just junk and move onto the next used one.
Just like the rocker arms and the push rods, the OE stuff is still much better quality than most parts currently available.

It was pointed out to me that the soft new screws work harden, so if they burr and then you clean them up they will remain in the same shape.
There was also a batch going around a few years back that were much softer than todays screws.
Swivel foot adjusters really go with solid rocker arms, as the stock washers and clips can be broken by the leverage of the adjuster rocking sideways off the valve stem . Happened to me once.

Personally I would go with the factory adjusters any day over all but the absolute premium quality swivel feet. Seen too many go bad, and it isn't pretty! I have a set on my bench now that we took out of a friends "noisy" engine. At least 4 were ground through to the balls and ready to expire |

I would like to piggy-back on with a question of my own.
With a CB "cheater cam" (lift .394) is it fine to use stock adjusters?

Yes, no problem. Right now my 2280 cam is even running stock rocker shafts although my next build I'm going to do solid rocker shafts. I'll still be using Factory adjusters |

Replace the springy washers with flat plain washers with any aftermarket cam.
It is not necessary to use bolts on the ends of the shaft, but using aftermarket rockers shafts does have the multiple benefits of costing more money, wearing out faster, possibly coming loose, and making it harder to adjust the shims.

When you see this happen...please make note of the brand when you can and post in one of the major threads for swivel feet.
Aside from the Mazda ball type....and aside from teh actual Porsche adjusters which are top notch....there are a few other brands out there that are kind of sold as "pseudo premium" that I give a hairy eye to.
An example...right here on Automobile Atlanta's site you have five different German made swivel feet for 911 and Porsche 914-6
https://www.autoatlanta.com/porsche-parts/hardparts.php?dir=porsche-914-parts§ion=103-10
Most of those mfgs....at some time or another actually made these parts for Porsche. That does not mean they are all equal. Some were Mahle. Some were Wizemann. Later still some were Mahle-Wizemann....and others.
Then you have these from CB...whose build quality is probably excellent but just looking at this picture...I see clearance issues around the cup
https://www.cbperformance.com/product-p/1518.htm
here is some of this same discussion from 6 years ago on page 7 of this thread.
https://www.thesamba.com/vw/forum/viewtopic.php?t=...highlight=
I also totally agree with one of your last posts. If you use swivel feet you STILL need to have very good geometry adjustment AND...should have solid spacers between rockers to get the best lifespan and benefit from swivel feet.

I bought an unbranded set of elephants foot adjusters .. and they stripped the threads on the rocker arms in a very strange way.. bound very slightly as they went in.. and peeled off a turn of thread. The thread pitch must have been fractionally wrong..

Were they the half ball type like Ford?mazda style or were they Porsche style (ball in cup)?

You took the words right out of my mouth. Shame on you 
Those, genuine Mercedes or Porsche.
I never use the stock adjusters if I can help it for several reasons. If they are used with lash caps along with stronger springs, then yes, its a cheap and functional solution. But you still have to do valve train geometry and you still have the extra side wear, so why not upgrade while you are at it. Done right, elephant feet adjusters quiet down the valve trains and aids just a little bit in increasing rocker ratio. So in my book it is a win win situation.
I believe Tabari has the Pieper adjusters on the shelf.

I wish someone made 1.1 rockers with the adjusters on the pushrod end.

What is so special about the 1.1 ratio? Other than the end user who has a 1.1 cam in his engine who does not want to split the case to install a ratio rocker camshaft to get the adjuster moved to the pushrod. Getting your desired lift from the rocker is better than getting it from the cam. The V8 world understands this. The Chevy LT1 engine has a 1.8 to 1 rocker ratio, in my opinion the best factory pushrod engine every built. We have 1.3 and 1.5 ish rockers with cup screws now. |

And there is no need. Half of the nanny stories floating around about this being bad and that not working well are originating from people who can´t figure out how to set up a valve train in the first place.
We just had this discussion elsewhere. The ACVW scene has increased significantly in parts prices over the last 3 yearts especially. It is not a cheap vintage anymore. Accept it. good parts cost money. If you want a cheap vintage, buy a V8
