How to check a engine before u buy??

I found a b16a1 with ecu/tranny/distrib. all the goods, and said it has 40-50K miles on the engine for $1500, I was thinking how can u figure if the engines good? sure it only has 40-50K miles, but what if the previous owner didnt change oil, ran low on oil, and burned stuff up or whatever? I am kinda iffy still on doing a swap, but the vtec, more hp engine with such low miles is starting to sound better and better…and I gotta get this swap so i can have a dang 5spd, I was gonna debate turbo, but im to poor for that. Any tips?

For starters, look into the oil fill area of the head with a flashlight. If it looks silver or natural aluminum, this means more frequent oil changes. If it is dark yellow or orange, this means infrequent oil changes and may also mean other neglect.

If they let you, pull off the oil pan and check the sludge at the bottom, does it feel gritty? Now look at the crank case for the same discoloration.
