Got back from our Christmas trip. Went to the dealer to pick up the lower valve spring seats I bought but one was missing. They ordered me another overnight (that is what I call service) and I picked them up yesterday. Today I had a little time in between granddaughters being born so went ahead, brought the head back inside and commenced work.
Here is one of the seats:
They are the same for both intake and exhaust, so you will need 16. Here is one of the old ones next to the new factory ones (new one is on the left):
As you can see they are completely different, and the one I removed has been hacked up. All of them were like this. Since the factory one does not have the markings I have to wonder where the ones I removed came from.
Here is a picture of a valve spring, the tight coils are shown on the bottom which is installed down nearest the valve:
I followed same procedure I documented before. I did try something a little different on a couple of the valves where I placed the keepers inside the retainer before setting it in place on the valve stem. This worked ok, although I had to be a little more careful when putting the valve compressor in place.
Finally, here is how I used the plastic to hold the keepers in place while compressing the spring:
I would recommend using clear plastic so you can see when you have the spring compressed enough for the keepers to fall into place. And that is all there is to the job. Easy-peasy.
