Rebuilding a BMW M50 cylinder head | e36 Drift Build Ep3

In this episode we continued to rebuild the m50 for my e36 drift car. Focusing on refreshing the head after getting it back from the machine shop who decked and washed it. The first task was to strip the head to be able to remove the value stem seals. To help remove the valve springs a valve spring compressor was used (see link below), 3D printed out of PLA. The valve stem seals were challenging to remove (recommend using the special tool). The valves were cleaned up using a scotch pad and lapped to improve their seal with the head. The stem seals were replaced and the reserve disassembly order was followed to place the springs and valves back into the head using the 3D printed tool. The head is now ready to be mated to the bottom end which will be assembled in the next episode.

How much you skim head by ?

I can’t remember sorry but it was only a touch

The guy isn't making those 3d printed valve spring compressors anymore. Can you sell me yours? Im in USA.

Hey man, I should be able to dig up the 3D printed file and send it to you! Dm me on insta!

Nice job getting those seals out. I'm at that point right now with my 92 325is. Not sure if you can help answer a question for me? Before sending the head to the machine shop for surfacing and cleaning, i removed the cams but left the valve and springs. When it was returned, the guy had removed the small elbow and gasket at the back of the head (heater water inlet?). What i can't figure out is where 3 small washers came from which were returned with the elbow. At first i thought they were washers from the spark plugs because they are similar in size. Any thoughts?

Thanks mate! Vert strange, maybe they are head bolt washers? Apart from that I’m really not sure! 🤔
