Miscellaneous ongoing maintenance


Replaced and re-glued the screens over both left and right fuel vent intakes.

There was a small weep of oil at the oil cooler / oil hose connections. I used steel fitting in the oil cooler (instead of aluminum) and did not get the oil lines tightened enough. I tried tightening them just a bit more while holding the steel fittings with another wrench. This seems to have stopped the slow weep.

I re-installed the engine air filter which had popped up from a small engine backfire during a previous start.

The alternator wire was chafing a bit. Fixed.


Changed oil. Took oil sample (was from end instead of middle of draining by accident). Changed oil filter. Did not change or check suction screen during this oil change.


Removed all 8 spark plugs. Determined 3 of 4 bottom spark plugs had lead build ups and decided to replace them (200 hours). Gapped the 4 upper plugs to < 0.020 and > 0.015 quickly but not very precisely.

Installed lower cowl heat shield material from Vans on the inside of the lower cowl to protect the fiberglass from the exhaust areas where it was starting to discolor.

Checking Magneto Serial Numbers

The magnetos installed on my IO-360-M1B Lycoming engine are as follows:

Left magneto: SN: 13050795, M-2983LH, Model: 4373

Right magneto: SN: 13050824, Model: 4370

According to Lycoming operator’s manual, the left magneto should be model 4371.

Slick/Champion service bulletin SB1-12 (corrected copy) is not applicable (SNs: 11110001 thru 12030902).

Magneto gasket part number: 62224?

Slick Mag gasket part number: LW-12681 (need 2 for impulse mag side)
