Hi,
I am looking at a pretty rust free '73 with a 1.7 engine. Car has been sitting for about 4-5 years without starting it. I don't suppose the engine is seized up from all that time sitting, but any suggestions on how to turn it over by hand to see if it still moves?
Read somewhere to put the car in 5th gear and attempt to push it forward. Would that work or is there a better way?
Thanks for the help.

Many thanks for the replies.
Assuming engine rolls over by hand. Now to start it.
I am reluctant to just pour new gas in the tank and turn the key.
Given the car has the original FI system on it, how can I get gas to the injectors under pressure from the fuel pump OR can I just attach a can of gas to the fuel line past the fuel pump?
Also, what is best way to get some oil into the cylinders. I assume you need or want a uniform coating around the cyl walls before you crank it over? Could I spray WD40 or similar in there.
Getting the engine started may the make or break on buying the car. Otherwise it looks pretty rust free.

I wouldn't let the engine be the decision point. Rust free chassis is way more important as a starting point. Sure an engine can be pricey if you can't do the work yourself but fixing a rusty chassis is an order of magnitude higher IMHO.

Regardless of what you do, there may already be irreversable damage to the cylinders. Horizontal boxer engines are notorious for cylinder rusting where moisture and/or engine oil acids migrates to the bottoms of the cylinders and can pit the cylinders.

WD40 is useless for the purpose you propose. Use PB blaster or other penetrating oil 1st to help break up any surface rusting. After that I'd put a few squirts of engine oil in though the spark plug holes before you crank it in earnest.
