What to look for when buying an engine or longblock
There are many things to look for when buying an engine or longblock. Most of the time when you go to buy a longblock you will see it is already taken out of a the vehicle, this means you cannot hear it turn over or run. This is not a problem because there are many things you can look for with a few basic tools.
You will need:
-? inch socket
-Breaker bar or very long ratchet.
What to do first:
The first thing you should do is take the ratchet and hook it up to the pulley wheel of the longblock. Have a friend hold the flex plate off of the ground and turn over the motor. Depending on how many cylinders the motor has, keep cranking until you feel the pressure build in every cylinder. Note: You must have spark plugs in the engine at this point.
What this tells you:
If the engine turns over at all that mean the engine is not seized up or does not have a destroyed bottom end.
If the engine is completely silent when you are turning it over that means there are no rod-nocks or any bad bearings in the block.
If you feel the same amount of pressure build in every cylinder, this means the engine is in good overall health.
What next:
Now that the engine turns over smoothly, open the oil fill cap and look around the inner rim. If you see any dirt or anything that does not look like oil, there may be contamination in the oil meaning the engine is bunk. While you are looking in the oil fill area see if you can get a glimpse of one of the cam lobes. These lobes should be smooth and shiny, if they are rough this is another indication of the motor being mistreated and possible bunk.
Finally:
Check the oil and try to find some coolant still in the block. If the oil smells burnt or if there is any contamination (oil in the coolant, coolant in the oil) that is usually a bad sign.
If the engine you are looking to buy passes all of these point, it is likely that you do have a good running motor and you are not getting ripped off.
