Hi Bobby,

I believe the things you have the arrows pointing to are triangular shaped braces that support the oil sump to the oil pan.  The are welded to top of sump and plate.

To access the bolts in the area of the sump, I stood the 4”x 4” tubing I used for the sump off from the pan about 1 – 1 1/2”.  I did this by using a 1” x 1 1/2” rectangular tube (its end’s plugged) welded to both the plate and the sump.  Then 3/4” dia  (I think around 6 holes) holes were drilled through plate, standoff and sump for the oil to return to the sump – probably best to drill holes before welding components together, but they can be drilled from the inside plate side – just make sure you get all shavings out.  This stand-off also gave you access to around 3-4 pan bolts.  Depending on your set up these may or may not be a pain  to unscrew, but it can be done.

The round tall blue tube served as oil fill tube and dip stick tube. It was threaded internally at the top and a threaded plug with a hole drilled in it for the dip stick was used.

The aluminum tubes were coolant (front) and air/oil separator (which I took off after two years of flying with it and it collecting no oil, because the rotary simply was not spitting any out.

Ed,

I have a couple of question about your plug up installation. How do you access the oil pan bolts located behind the oil reservoir and allow for oil drain back? Also I see what looks like an additional tube (black arrow) in the attached photo. Can’t figure out what it’s for. Is it a  support bracket?

Thanks,

Bobby Hughes
