M1M, Having sat behind aTIO 540 S1AD for the extended lives of two, the only problems encountered , to be expected, were the accessories. And once the Ed fuel pump..!!, so make sure the electric pump is always kept in good working order.
Not something that was ever done in 100hrlys.! Easy to pull out and service every 5 yrs or earlier if any unusual sound of. Was glad I did that, see above!
Was operated as per the book, in a job that was mostly cruise settings 24/24 all day. Photo mapping.
Main thing in the Turbo Lance, which has a deficient airflow cooling arrangement was to shallow climb at higher speeds in very hot conditions to keep the oil temp away from the red line.
Idling for 5 mins or so to run down the turbo speed was the go. One turbo on one engine had to be changed due bearing issues.
No prime for hot starts.
Having operated a like Turbo Continental, was always having to pull pots. Not so with the S1AD
Thank you Mr Lycoming for keeping on, keeping on.
Note you have a non turbo. Like any donk…look after that and it will look after you.
