1991 Buike Reagel, overheated, found oil in radiator...?

Some say cracked block, but nothing on ground under car, and some say blown head gasket. Other than this, this is a decent car. Is it worth trying to repair. Not much of a mechanic.1991 Buike Reagel, overheated, found oil in radiator...?
That does not mean cracked block as another user yelled out, Tho that doesnt rule out cracked block either. You probly have blown a head gasket or cracked a head... a head will go out long before the block gives in. the 3.1's and 3800's that came with the regals have rock solid bottom ends so I severely doubt you cracked the block. Its worth fixing because its cheaper than getting a new car but DONT drive it with how it is.. water dilutes oil and your bearings wont like it to much. Run a compression check on the engine and find out which head blew.. ORRR pull your spark plugs, one should be alot cleaner than the others are. It might seem a little scary to do this but if you want email me and I can help you as best I can with the job1991 Buike Reagel, overheated, found oil in radiator...?
That means cracked block.
Check for this:


1. Let car run and see if it overheats


2. White smoke coming from the tailpipe


3. If there is white smoke, does it smell sweet?


4. Also, check your oil and see if coolant is in your oil.





If your car tested positive for any of these, you are looking at a head gasket case or intake manifold gasket case.
