S-Arvind;
I'm aware of that mod. Seems like a good idea.
However, if the engine has been inactive that increases the possibility of cam/lifter issues.
Where is the airplane located?
Do you have access to the recent flight and maintenance records (dates of flights, dates of oil changes, etc.)

Thank you Steve. The Aviation Consumer article refers to a high rate of NTSB accident reports on the PA-28-140 model specifically due to engine failures.
As far as the cam and lifters, the previous owner overhauled the O-320-E3D with the Centri Lube Camshaft ( firewallforwardengines.com/stc/ ).
The claim is that this innovation reduces the risk of camshaft and lifter failure significantly.

Hi Theo,
I need a better explanation of the problem.
Is it that the strut has too much extension when it's on the hangar floor?
If that's it, then I would suggest that it be serviced with hydraulic fluid (Mil-H-5606A or Aeroshell fluid 41, among others).
The correct method is to relieve all air pressure in the strut while the airplane is on jacks. Remove the valve core of the filler, and then slide a flexible plastic tube over the filler. Put the other end of the tube in a can or jar of clean hydraulic fluid.
Then physically move the strut up and down to fully collapsed and fully extended until there are no more bubbles coming out of the tube end in the fluid when the strut is fully collapsed.
While the strut is fully collapsed, remove the tube and re install the valve core.
Make sure the valve core is a high pressure core--it must have a small "H" on the head of the plungers stem.
Take the airplane off the jacks. Service the strut with nitrogen to the proper extension.
If I have missed something or haven't understood the problem, please provide more description.
If this servicing process hasn't been done in the order described, do it and then see if the problem has been solved.
Thanks
Steve
