I am removing the cilinderhead of my 3.8. I already removed all the screws and the camshafts. But when i want to put him of, he doesnt come al over. Do I have to remove the valves to?
The cylinder head is a two piece construction. The (1) camshaft house and (2) cylinder head. The removal of the camshaft house requires the removal of the camshafts, the valve-buckets, the 28 hexagon bolts above and below the valve buckets, the four hexagon screws on the front and the back cover on the rear. When all this is done, it must be possible to remove the camshaft house.
This exposes the cylinder head with the valve train. The cylinder head itself requires the removal of the 24 9mm copper nuts of the exhaust-headers (real PITA job) and the 14 head bolts. The rest is straight forward.

Just removed the valve buckets and now the camshaft house is off, so thanks Raymond!
@t Hessel, i had 2 3.8's one in my own car, and a single 3.8 in stock.
The one in my car needs only a new valve.

Let me guess, an exhaust valve?
Before drawing premature conclusions, have the cylinder head checked by a reputed engine specialist for proper seating of the valve seats. IMHO, it is sacrilege to just replace one valve. I can imagine that after carefull inspection, the intake valves can be reused, but the exhaust valves run much hotter and wear at an accelerated rate, especially when one already is broken.
You are right in there. I had an opel vectra with the same problem, so thaught it would be oke by just removing the valve. But do you think it is nescesary to remove all of the valves?
My car has been stolen from a 92 old man, since then te valve is dead.. So i thaught te problem is that the thieves didnt do a warming up run, and thats why the valve is dead.. or is this a wrong conclusion..?

It's an assumption. Furthermore, a previous owner at age could have been an enthusiast when he bought the car (new?). But when aging!, he has to live with shortcommings that comes with seniority. Most likely children that make decisions for him. How do you know that the car has been maintained properly ? Most likely children that don't like to see a multiple thousand Euro bill for maintaining their fathers pride and joy or the owner himself not able anymore to use and maintain the car properly ? (e.g too many short distance city runs)
I think that the two facts combined led to the engine-dismay and not just a single fact alone.
For the record, I am having my complete engine overhauled at an engine specialist and asked them to measure up anything. It doesn't make sense to reuse old parts that look visibly OK, but of which you are not certain. Bear in mind that teh difference between OK and worn is not necessarily within visible range.
