I'm going to do a valve job on my 86' 300E I was going to see about just getting a rebuilt head and bolting it on & done deal, well I'm finding the diffrence between that and simply taking my head to a machine shop getting the guides replaced & valves & seats cut is way off. I called EIS a supplier in STAR Magazine he wanted 1800.00! I asked him why, he said it included the cam, and that if I tried taking apart the head that I would have some horiable problem w/ the lifters, he said he had 3 other people on the line and had to go... so my question is has anyone ever adjusted or worked with the lifters on a 103 motor? I've done plenty of BMW's, no problem, I glanced thru my manual I didnt see any refrence to lifters, maybe I should look under jack stands, I really hate that book. So does it use shims? I know there hyduralic, but thats it.
Thanks for any help. Chris C.

I have had much experience with the 103 valve job and here is my advise. If the top end is not making any ticking sounds, and you feel comfortable taking the cylinder head off by yourself, do it!

Tips:
1. number the tops of the rocker assy's before you remove them.
2. when you remove the rocker assy's, be sure not to loose the adjustment shim located just under the lifter.
3. when you get the rocker assy's off just submerge them in a small bucket filled with new oil this will protect the lifters.

4. MOST IMPORTANT!!! Take the head to someone who is very very familiar with the job!!!!
