If you relish the challenge of trying the inner workings of fine german engineering...
You should get yourself the HG kit
. You could
get yourself just the HG but if you've got the thing open that far, you might as well be replacing all
your O-rings and seals related to this job...The kit will cost you $170-$300.
You'll also want to have yourself a new
set of head bolts. DO NOT REUSE THE OLD BOLTS
The job can
be done without the BMW special tools (TDC locking pin, Timing chain tensioner, Camshaft alignment tool, and...if you're replacing the valve seals, the camshaft bearing compressor tool) but this isn't a recommended practice. The tools themselves can be had at least for the price of a good mechanic.
Expect your car to be inoperable for at least 3 days depending on the amount of time per day you have to spend on it...it took me a total of 9 hours all together with no special tools and no shop to work in (regular backyard garage).
If you don't have a DIY manual (Bentley or Haynes or Chilton), you can find yourself some pretty informative articles here
Do make sure that it is
the HG causing your grief....it would be a shame to go through all this to find that there was no problems with your head gasket in the first place. E36s are, unfortunately, notorious for cooling system problems.
Good luck with your endeavors, whichever you chose to go with.
