Take the shims to an Engineering place with a SURFACE GRINDER and get them to grind them down properly, sanding them on a stone or sandpaper won't work, whatever finish you get with sandpaper you will put back on the component that the shim runs on and it won't be parallal, or go to an Alfa Wrecker or Specialist and buy the right shims, Colin.

hey col,
I have been bitten one too many time by so called " Specialist" that is why i am having a go

[colcol]

Now that you know what size you want, buy some new ones or have the old dunger shims that are worn or have pickup on them ground down accurately on a SURFACE GRINDER, but only a few thou, as you don't want to grind through the hardened coating, i have done this for my old Volksy and Alfa 33 and Alfasud and it works fine, don't waste your time sanding them down, it won't work properly, the shims have to be dead flat so depending if the camshaft has positive or negative this will rotate the shim so that wear will be averaged around on the shim and not just on the one spot, Colin.

hi

thanks for the advice, I think I will do exacly what you have suggested.

any one know of a person in Adelaide that can do the grinding?

Just tying to get my leads back from top gun atm, so I can get it running. They made them wrong the first time. I sent the my old leads and they still got them wrong. So its a waiting game atm.

Thanks for the advice
Cheers.

Try an Engineering Shop or and Toolmaking Place in Adelaide that has a surface grinder, but hurry up before they close down along with the demise of our car industry, Colin.

TOO TRUE  It all a bit grim .
The only way to get by is working for a big cars parts shop.

hi all,
I've finally got the car going, but it sounds like a hairy goat.
I tried to set the timing, but it sounds like its hunting.
The timing mark is at the pin then it's gone and then its back then gone again and so on???
I'm thinking that I will have to reset the timing again.

Any Thoughts? TA

hi all ,
I'm feeling a bit annoyed .
So the reason that I am having no joy with my heads is because when they reconditioned the head they lapped the valves in so far that the shims were out a lot. Hence rough running.

So now.... to get head off and get the reconditioning guys to make the shims fit.

Not happy... its another $400.00 to spend.

If your planning to recon your cylinder heads.. best check your valve shims.

oh and it continues... bugger.

Only backyarders lap valves in with valve grinding paste, the cylinder head seats should be cut with a single angle tool, the valve should be dropped in and a vacumn test done to check for sealing, the valve should be ground on a valve grinder.
Then the valves should be assembled with the cams installed and the valve bucket to camshaft clearance measured, then to achieve the correct clearances, the cams are removed and the shims changed or surface ground or in some cases a few thou nibbled off the end of the valve stems.
Do a compression test to see if you have compression in all the cylinders, the valves may not be closing or seating correctly, Colin.

Check that the shim walls aren't bottoming out on the collets!

Thank you both, very valid point.
I would have thought this would have been pointed out by "Chris Milton engineering" the business who did the job originally.
I would have thought for *&^% $850 he might of let me know 

Plan B
Looking into a 3L replacement. Might be the best option.
Cheers guys
Thanks
