Graham at CIAS kindly dug out the engine oil I need from stores so its ready to go in once I have finished fiddling with the oil cooler. Managed to work out last night that with the cooler on I cant get the lower cowl on and off !
I reckon that with the cooler matrix connected I will be able to remove the lower matrix scoop, and support the oil cooler on a temporary bracket on the bulkhead when removing the lower cowl. May even rivnut a hook on for that purpose now.
That would mean – a full lower cowl removal would take approx 5 minutes or less, so not too bad.
