Hi, I need some advice,
I purchased a very nice 1973 911t 2.4 mfi
That has been sitting in a garage for the last 25 years. Engine and trans where rebuilt before being stored.
Any tips or things I should do before starting the car?
Other than oil change?
Any priming or things I should know?

Be careful... that is a very valuable engine.

There are many possible problems with engines that have been sitting. Oil turns to sludge, old gas goes bad (this can really mess up your irreplaceable MFI system), seals and gaskets dry out and leak, and rings can corrode and stick to the cylinders.

At a minimum, you may try to carefully turn the motor over by hand to see if it is seized, but I would not try to start the car until all these things have been addressed... I'd put a very careful plan together before I did anything.

There are a lot of existing threads addressing this, and I'm sure some of the more knowledgeable guys will weigh in here.

Thank you so much for the your help,
I drained the old gas, and engine does turn over, but does have an oil leak-coming from the right side of the engine.
I going to plan very carefully before I do anything to make sure I cover all my bases.
