As for today, we are talking head :








All moving parts went out easily:








A lot of dirt:





Needs a clean-up, and a refresh:








Poor valves, dirty ones...:






All this looked as new, my guess is that the head have gotten some new parts not long before I bought it.






But... I bought 12 valve guides from VAC, in original size (8,0mm) of course...





Five of the exhaust valves are oversize 2 (8,2mm), and one is standard (8,0mm).





So the I had to get hold of five new exhaust valves, due to the motorshop where I am going to have my valve guides replaced do not have 8.2mm Brotch.


I measured the guides, tolerance-spec says 0,8mm - and this valve has a movement of 0,7mm - so I want to replace them all...







First of all, I needed to make sure the surface is clean and straight.

Before:

After:

They machined 0,15mm off the head, so that was not too bad for a 6-cylinger head...

Even more clean...




Valves needed cleaning







After some cleaning:






Atleast looking better:





This is how I stand per today 04.01.2012. I have sent the head away to get following work done:

- Grinding valve seats (Mira) 3-angle
- Replacing valve guides (VAC Motorsport edition)
- Valves final clean-up and machined

So now I am just waiting for the shop to get finished, I really want to get the head assembled and into position...

Sorry, I forgot... I did some small things too...


I had to finish the Alpina-tank vent system...:






Hoses correct measure, and attached:






Looks almost as original?.







Remember my old battery-tray?





Bought one from a user in here, thanks a million!!!








NICE!!:






Primed:






Looks even better with color?






Into position:






I like what I see, compared to the old rusty fart:






Carpets in position. Looking bad, but they are the only ones I got. Anyone parting out a M5 trunk carpeting?






And finally, the last door came from paint-shop, ready to rock'n roll!!






Almost getting the E28-feeling back now...







And some off topic...

As you might remember, X-mas was just here...

Here is my little boy getting his present for Xmas





His sister was exited too, and wanted to help him out - all went too late she thought.









Try out...





Mistake... He was sitting there for the rest of the night... Honestly, I think it is a good thing...
