Routine Maintenance and Fluids

I completed a bunch of standard maintenance items on the car.  With this car, I elected to buy some parts and filters that are original equipment manufacturer, but not necessarily in BMW boxes with BMW part numbers.  There is money to be saved this way.

The power steering reservoir comes with a new cap that says "CHF 11..." on it.  That is the new power steering fluid BMW uses and is not right for the M coupe.  M coupe should have ATF.  BMW does sell a little green label that says "ATF" (part 71246798132) that is supposed to go onto the cap to cover up the printed "CHF 11...", but it is $15.84r.  Even I think that is nuts.  I know there is ATF in there, I know to use ATF, so I am leaving the $15 sticker off.  Incidentally, the single 10mm bolt that holds the P/S reservoir to the car is a real whore to put back in place.  The bolt is very short and it's hard to line up with the welded nut on the other side.  The fix here is to totally remove the P/S reservoir bracket from the left side motor mount.  Two 13mm bolts for this.  Once completely free from the car, the P/S reservoir bracket will get a little more flexible and you can get the 10mm bolt started.  I spent a stupid amount of time fiddling with the 10mm bolt before I figured this out.  Incidentally, the way to bleed the P/S system is start the car and turn the wheel lock to lock several times.  I removed and replaced the lower power steering hose in order to drain the maximum amount of fluid from the system.

In the process of replacing the transmission fluid I found a crack in the giubo/driveshaft flex disk so I will be replacing that in a future post. 

The valve cover wasn't leaking any where and you can change spark plugs without disturbing the gasket, but I wanted to look inside the engine anyway.  Very nice color and very good indications of a healthy, well-cared-for engine.  So that was good news.  Plus, new gaskets are fun.

I am planning to replace the radiator in this car with an S54 radiator and add an S54 oil cooler at the same time.  But, I am not sure when that will be.  So I am changing the coolant now just because I have the car on jackstands.  ~$20 for coolant is a cheap might-as-well.  I replaced the coolant drain plug with a LeatherZ / VDO drain plug so my to-be water temperature gauge can read the temperature there.  More on additional gauges later.

Used brake fluid.  Not a good color!

I was very happy with the colors and wear indications inside.  Testament to the previous owners and/or Amsoil.

You can see a tiny bit of wear on the round parts of the cam lobes.  This is not there on the S54 engine.  Do all hydraulic lifters do this?

New gaskets

Add Drei Bond at joints

$15 green sticker designed to fit on cap not shown!

10mm bolt on lower right side of the reservoir

Oxygen sensor needs to be trimmed about 1/4" to allow the block drain with sender to fit.

Crack in the giubo, although out of focus, is there.
