I have an interested buyer for my 280e euro motor. Foolishly I removed the engine from the car without doing a compression test. The buyer wants me to run a compressoin test. I want to do so and I want to be fair to him and to me.

The engine was run for about a half hour a couple of weeks ago before removing it from the car.

I can crank it over with a battery and jumper cables to do the compression test.

My question is should I do anything with the bores before running the compression test? Put in any liquid before testing or just go with whatever is in the bores at the moment?
