The oil drains off of everything would be my answer to the compression loss ?. How do you know it's losing compression? Have you checked it? Because it's hard to start?



"how do I get it started"



What's going on? Give us something to work with.



Cheers

I say that because when it turns over it sounds just like a piston motor with no timing chain...spins real fast an easy...

sounds like the oil film just drains away and you lose all compression. Put some atf or mmo into the spark holes and crank it. After that just start it once a week, even if you don't drive it just let it run.

you might want to check your oil injection also to make sure it's injecting enough oil.



Another thing worth checking is your fuel injectors, they might be leaking and contributing to the washing off of the oil which normally lubricates the seals. The oil is used for reducing wear on the seals, improving compression, and preventing corrosion.



If you're new to the car and plan on doing the maintennance yourself, I recommend getting ahold of a shop manual for your specific model/year. http://racingbeat.com has reprints for sale, you can also find them on ebay sometimes.
