Another Brief Return to the Firewall Forward

As with the brief return to the fuselage work (autopilot pitch servo), I also took the opportunity of some slack time, to mock up and finish installing the oil breather assembly.

I ordered a different K&N air filter that would yield more surface area as well as provide a larger entry point for the attachment of the 1 inch oil breather hose that is routed from the oil tank and then to a breather cap.

Shown below are pictures of the modified K&N air filter that was drilled out to accomodate the oil breather line.

I affixed a hose clamp on the inside termination of the hose residing in the filter body.

I used a tight fitting washer bonded to the filter with some Permatex Right Stuff gasket making compound, followed with another hose clamp.

The two shots below show the installation of the breather assembly on the engine.

Another brief task involved the installation of the radiator shroud.  First task was to give adequate clearance between the shroud and the cowling.  After a trial fit, the two areas that were closest to interfering were marked and sanded as shown below.

Next, it was time to bond the shroud in place with the prescribed Permatex product, The Right Stuff.  A healthy bead was laid around four sides and clamped into place.  Done in an hour.
