Lashcap issues/valve cap issues

Hey,
I posted this once before, and searched the internet up and down, but i never really got an answer.
Basicaly what is happening, is i have a fresh 300 tdi, that had about 17000 miles on it. It was the rebuilt up using genuine LR parts, or OEM... no Britpart.
Once the engine was installed, it turned over fine, and is running with no performace issues. The exhaust is barley visible in both idel and use.
But when we went to check the valve/lash caps at 1000 km, they were worn and needed replacing. So we replaced them with Genuine LR ones not OEM ones...Re did the valve adjustments ussing a .008 or .0203mm feeler gauge. Then dumped the oil, removed the pan, and cleaned it all out to remove the small metal bits perduced by thier wear. Once the oil change was complete, ran it for 600 more km and cheked. These caps are even worse. There is one that has been worn out so bad it is nothing more then a dougnut now Does any one had any issues as to why this would be happening?
any thoughts? we have pulled front of the truck apart and double checked the timing. Timing appears to be dead on....
thanks
craig

Sounds like junk parts. Or adjusted incorrectly.

I use hardened lash caps from an Air Cooled volkswagon. EMP makes then, should be available on ebay. A big improvement over factory or other makes quality. Only 10 dollars or so a set. Have done this for a couple dozen or so engines now. To many problems with factory lash caps.

Some time back many factory new engines were released with non hardened lash caps.. Or at least not hardened correctly. Lot of failures resulted. It is an ongoing problem and weak point of the engine. The EMP caps are a better option.

poor lubrication (due to excessive fuel in motor oil or weak oil pressure), defective parts, loose lash thus causing tapping (I don't now the proper lash of these motor), bent push rod(s), valve springs too heavy to compress. are some issues which come to mind inmmediately.

The stock ones will move around. Especially when they start to mushroom. These ones will be a tight fit. Yes your local VW Dub place should stock them, for the air cooled tuner boys.
