I began my rebuild when I did a compression test and noticed I had poor compression in cylinders 2-6 (about 142 psi, the bottom of the service limit). Cylinder 1 head 160 psi. A leakdown test showed leakage into each adjacent cylinder. Of course my engine also had the oil consumption problem (1 quart every 1000 miles) that every M54 engine has, which is caused by the oil rings which wear down prematurely (the M52TU used different oil rings which did not have this problem). There was also coolant loss, which I didn't measure precisely.

The remover tool from Lisle is 36050 and it's available here: http://amzn.to/2hUTqfH

All you need to make my installation tool (which can also be used as a remover, btw) is some 1/4" thick steel stock about 1" wide by maybe 2 ft long (just in case you make a mistake cutting it).

You also need some basic metal working tools, such as a drill and drill bits, a cut off wheel, maybe some files to smooth down the burrs. Nothing major.

You can find the Milwaukee 2457-21 cordless ratchet that I used in my amazon store: http://astore.amazon.com/50skid-20?no...
