Title: DIY engine tools
Post by: ToniBmwPortugal on April 20, 2012, 07:55:03 PM

Hi there to all!
I've been reading and reading on this forum and i got to a point that i've decided to make/rebuild my own engine.
But this lead me to a problem: what tools are necessary...
So i started this thread to we discuss about the tools: specialized (BMW) or not that are required to work on our cars, especialy the engine. The idea is to make a list with the tool and the function to what is required.

P.S. I'm sorry for the bad english (i,m a Portuguese guy)

List with tools:

-flywheel lock (pin part # 83-30-0-490-861)
-camshaft holding tool
- ...

A hub holder to aid in removing the fan clutch.

You'll need a long torx socket for the head bolts too, from what I've heard.

Pipe fittings can be machined (sort of requires a lathe) to install rear subframe & trailing arm bushings.

The crank bolt is super easy to loosen...you just need a 4"x4" block of wood and a breaker bar. You then use the starter motor to smack the bar into the wood block until it comes loose.

Tightening that bolt requires some sort of locking tool. I made one out of some 1/2" thick steel plate and a drill press (bolts to the 6 accessory pulley holes, rests against same wood block on driver's side that was used to break it loose).

Yes, you need a long thin torx head socket to remove the head bolts with the cams in place.

Technically you are supposed to have a tool to loosen the cam bearing caps. You can also remove the caps without the tool by Loosening/tightening the nuts in a star pattern from the center 1/4 turn at a time. Takes a while, but if you go too fast the hollow cam can snap!
