I brought it to a so called mechanic off craigslist and he said my whole engine was shot. I did have a slow oil leak in the car from a place i had it changed when they punctured a whole in it. But the car had oil in it at the time of this. I checked and it was lower than normal but still had oil. I have a hard time believing that since I have had no major problems with it. Is it possible to just be the belt?

It's very common for the turbo return line seal to leak. That is what I would check first, when it leaks, it will spray oil all over the turbo lines and the rear of the engine.

look in the trunk... either it has side panels that can be removed... or you will see a hole in the side of the lining with a sticker that points out where it is.

SOURCE: 1988 Volvo 740 Smoke from Oil Cap and Dipstick hole when removed
The smoke coming from the valve cover and dipstick is called blowby. It is combustion gases the have passes by the piston rings . A small amount of blowby is normal on all engines. The PCV system(Positve Crankcase Ventilation)pulls the gases out and directs them back into the egine to be burnt again. I would first check the PCV system to make sure it is working proper. Also a compression test of the engine will tell you which cylinder is not sealing proper. If the compression test is ok, a leak down check of the cylinders will determine if the engine is wore out.

Water in combustion chamber makes white smoke--suspect that the head gasket is leaking water into the chamber. If oil leaking around turbo, it may have a bad bearing and bad oil seal. Check waste gate valve and control.
SOURCE: How do you reset the check engine light on a volvo
The Check Engine light has nothing to do with changing the oil. The light is on because there is a problem with the emissions system. Even if you reset the light it will just come back on unless the problem causing it to come on is repaired. You will need to have the ECU scanned with an OBD2 scan tool. That tool will retrieve the code that has been set by the ECU. The code will tell you what part is being effected, but not necessarily what part or parts are defective. To determine that takes training, experience, and diagnostic skills. I suggest you seek professional help. If the engine is running fine there is no hurry but if it is not running as it should, then do not put this off.
Hello
When the service engine
soon light (Also called the check engine light or engine management
light) is turned on this is to alert you to the fact that Powertrain
Control Module (computer) has detected a failure somewhere in the
systems it controls you may not feel any difference in the way the
engine runs, this can be the transmission or the engine or emission
system, there are fault codes set in the modules memory for these
faults. What needs to happen now is to have the powertrain control
module scanned with a special tool called an OBD2 electronic engine
control scanner or a OBD2 code reader. Once the code(s) are read then
you must perform the diagnostics for each code and make the
appropriate repairs based on the findings of the diagnosis that was
performed, this is called doing "Pinpoint" testing.
