BMW special tools. Why nothing online?

[xboss]

Hey all,

Just about every darn job in the TIS has "special tools" needed for one thing or another. There is a handy part number listed so great! However, you can google the heck out of these numbers and find nothing online. Some of these tools have three or four part numbers of little parts building one tool etc. Very confusing.

I'm trying to get ready to do the cylinder heads and it's incredibly hard to find what I need to compress the springs and release the valves to do the valve seals. Where can I find these tools? Hope they are not big bux.

I used this compressor for the valve job a few months ago, worked great.

OTC unit, good cup size for working the keepers out and in. Magnet to remove them, small hemostats with long handles to insert.
It is patient work, very small keepers.

That sounds awesome! TY.

Was that a Paul sighting we just witnessed?

[oldroller]

Yes I believe it was. I would just love to go visit Paul's stable so I could drool tastefully...

samstag is confusing and the bmw special tool numbers mean nothing on that site. Seems like the only way to get the proper tool from them is to call.

Just a note X...when I did the heads on my 155K M62TU I pulled the keepers on all the valves on the left head and found the original seals to be in perfect condition,
still pliable (had two bent intake valves). I replaced the seals while in there.

On the right head (no valve issues) I pulled #1 springs, and the seals were again perfect. I replace those two, left the rest alone. Very tedious work.

The M62TU does not have a history of valve seal issues. They are very small valve stems, evidently cooled well. I have had no oil smoke on startup, no oil use/loss since.

I hope my M73 is the same! I do not really want to do them but I figure if you have the heads on the bench and the seals come with the head gasket kit maybe they should be done. I will have to decide once out. TY!

When you pull the keepers it is always good practice to lap the valves (probably already know this) with a fine paste, such as Clover lapping compound.
It renews the valve seat to valve face contact point. Also allows you to see any possible issues with either face.
I have used Clover for over 40 years on a untold number of engines/transmissions/pumps/etc, best stuff imho.

Been wanting to get my hands in an M73... such a beauty!

Many/most special tools can be looked up at a dealer with part number 83300 + 6 digit tool number, though many of them have been superseded by new numbers.

But I'm guessing valve stem seals can probably be done with generic tools.

My dad had engines on a stand my whole life. I used to love helping spin the valves with that paste!

When I was in high school motor shop (dating myself to late 60's early 70's) they taught us hand lapping with a little suction cup gizmo with a wooden spool. A friend mine told me some people now use reversible drills to do it. We use to do it to high mileage engines - prolong the life before a new top end job.
