180J O-470R cowl flap interference
Author Last Post
 Mine goes straight down but through out the years things change. Look at the parts book for the correct, or at the time the way the factory did it. The trick is to keep the oil from sucking out the tube, if you have little oil on the belly then I would say it is working as it should, I have seen where there has been a cut out in the cowl flap but if you can help it don't do that maybe just shorten the tube.

Very little oil on the belly and I’d say motor is maybe using1qt/10-15hrs. Yes the breather is attached to firewall but not a separator or catch bottle . So it is supposed to be bent at a 90* aft? Can you post a pic of your own breathers?

Thanks,
Jamie

 

Here is one from a 79 185.  It's the big one to the left under the cowl flap.

  That is some kind of breather, is this direct from the engine or out of an air oil separator, usually it is a 5/8 aluminum tube that comes from the engine vent on the top forward part of the case, make sure it has a 3/16 hole in it some where just above the bottom of the fire wall. Lots of times the end of the tube will be cut at an angle with the cut facing aft, you do not want to create a low pressure as this will cause the oil to suck out of the engine that is one of the reasons for the hole above the end of the tube the other is for ice. Cut straight and flat is not recomended, do you experience oil on the belly?

It should be bent back to 90 degrees to accommodate the cowl flap.

Just getting acquainted with our 180 and seem to have some interference with the breather and cowl flap. Below are some pics. The cowl flap won’t close past 3/4 due to hitting the breather. Out of curiosity where is your breather routed?

Thanks,
Jamie

Jamie - mine is SCAT tubing and stops just short of where the cowl flaps meet the firewall. It’s routed along the firewall. 

Your installation is strange indeed.
