Engine and Avionics

EGT sensors connected ( 2 hrs )

Per Sect 48-07,  Steps 1-3 completed wiring connections to 4 EGT sensors.  Added safety wire to hose clamps per Alcon Tempest instructions per their recommendation.

EGT sensors (and more Fuel System leaking ? )  ( 3 hrs )

Back to trying to find leak in Fuel System !  At first, thought yesterdays leak discovered and repaired completely solved Fuel System "leak"...but after 1 hr, the 30 psi air pressure slowly dropped.  So today repeated - and now won't hold pressure for more than couple minutes.  Redoubled efforts with lots more soapy suds...thoroughly covering every possible joint or leak path -- No joy.  To confirm not test equipment, I positioned Fuel Valve to OFF...and it held pressure.  So considering if internal leak in valve from LH to RH side. But tested for air transfer to RH side (tube added to fuselage fitting, ending under water...no bubbles!) -- again No joy.   So tomorrow I'll try to isolate (remove hose to engine fuel pump, cap and test that section)...with more soap bubbles.   Meanwhile installed all 4 EGT sensors Type K thermocouple (from Garmin G3X sensor kit, Alcor Tempest #86255, which is Garmin #494-70001-00).  Reamed holes (pleased already drilled in exhaust tubes) w/ #30 reamer since press fit.  Need to finish wiring connectors, add safety wire.

re-checking for leaks in fuel system...

getting frustrated....total immersion seeking possible leak
in "red cube" fuel transducer itself, as well as connections

EGT sensor installed, still need to connect wiring.
Sensor is press fit into #30 hole...so tight and leak free

Exhaust and Fuel System ( 2 hrs )

Completed Heating System w/ last DG-12 adel clamp on engine mount tube, attaching DG-32 holding 2" SCAT hose to LH Vent.  Finally...yay!  Repeated 30 psi air pressure leak test of LH Fuel System (I ordered/received AN 6 sized cap for RH side to insure not leaking during test).  Using soap suds, discovered tiny leak between Fuel Pump and Fuel Filter on pipe threads.  Disassembled, re-applied thread sealant - and NO leaks for 1 hr.

2" SCAT hose routed to LH Vent.  Clamps
position hose clear of  potential rub points

Discovered tiny air leak at pipe threads during pressure
 test (center of pic).  Bubble grew over couple minutes. 
Removed inline filter from Fuel Pump, re-applied
 pipe thread...no leak.

Engine

Exhaust ( 3 hrs )

Installed lock washers under Exhaust flange nuts, & torqued to 190 in-lbs per 48-03, Step 7 & 8.  Needed special 1/4" drive, 1/2" flex socket -- only way to fit onto nuts since exhaust pipe clearance is minimal (VAF has posts noting other builders found same solution.  Surprised Vans instructions don't call out this tool requirement)  Added Sniffle Line Assly per 49-18, Steps 1-6.  Required adding Bottom Cowl Support Bracket plus couple more adel clamps.

1/4" drive, 1/2" flex socket barely fits...
to tighten exhaust flange nuts

Added heat shields in 3 locations

Sniffle Line Assembly installed.  Yellow cap has blue tape to insure I remove prior to 1st  engine start

Heat Muffs, etc ( 3 hrs )

Completed Step 6, Sect 48-05 - 2" Vent Tee.  Limited space to 1st install two Adel clamps to engine mount tubes, then very large Adel Clamps around 2" Vent.  Used safety wire to hold clamps in position.  Overall took a lot of time to get positioned correctly - and lots of various tools!   Glad that's done !

Using tool to hold clamp closed so I can
hold closed w/ safety wire

In the end, I used many tools to get  'er done.

Heat Muffs ( 3 hrs )

Installed Heat Muff assemblies per Sect 48-04, Steps 1-6.  Added couple of the SCAT 2" hoses per 48-05.

1 of 2 heat muffs added.

Both heat muffs added, & interconnecting SCAT hose installed

hose connected for air intake 

Shop Set Up

LED lights added in Hangar

My wife helped today install four 4' LED Shop lights in newly rented hangar.  ( Search Amazon "4 Pack LED Shop Light for Garage: 36W, 4Ft, BBounder 3600 Lumens"  Only $60 for all four.)  The airport staff brought a big ladder that worked perfectly. With Nancy's help, the project got done quickly.
