Thread: Opaque oil window

  1. #1

    Opaque oil window

    I just acquired a 2004 r1150gs with 83k on it. Love it, but cannot check the oil level because the window is opaque. Anyone run into this problem? Suggestions for remedying? Thanks

    Welcome to the forum! Seems I've read about this lately...you might look at some older threads in this forum. The thread cutoff might be the last month, but if you go to the bottom left, you should be able to extend that to a point further back in time.

    I used the google search feature and the top and entered this:

    site:bmwmoa.org "opaque sight glass"

    I got some hits...you might want to read through those and see if that helps any.

    Past the time to replace! It is very brittle at this point.

    A 3 on the difficulty scale if you feel like tackling it.

    Easy at one level, but must be done with care to avoid breaking the replacement sight glass window during installation.

    Don't want to, will not start an oil string but,

    I used a particular brand of synthetic oil in my Oilhead and my Brick/Bricklet and it stained the sightglass to black in one season. We used the same oil in my buddies Oilhead and another Bricklet and found myself replacing all the sightglasses.

    Easy way to change the sightglass, read it here somewhere, it is a 1 on the difficulty list, use a soldering iron, melt the plastic right through, use a cotter pin puller and it pops right out.

    Part is cheap

    And repair is easy. Look on Youtube and you will probably find it there. Research it now and do it next oil change.

    What was the brand? I have used Castrol synthetic for the last three oil changes and now cannot see through the sight glass. Is it only Castrol synthetic that does this or is it synthetic in general?
