OIL Tank Metal filter
Just a quick question If I take out the Metal filter out of the oil tank to clean it , do I need to purge the system ?
The Issue I have is on a flight yesterday I noticed the oil gauge fluctuating between Zero and normal operating pressure , on landing I checked the engine over no visible problems seen.
Not sure if you remember but a couple of months ago I had the problem to higher a pressure which turned out in the end to be a faulty connection, I Did at the time replace the pressure release vale with the new mushroom type since I done that it has been reading a little lower than before but well with limits. So I am thinking I may try the ball and spring again just to see if that stops it fluctuating , then I thought may be the filer might need cleaning as it has not be done before The engine is a 912uls with 366hrs since 2008.
Your Thoughts please .
John.
