Re: just did rebuild on 5.2L motor head gasket was blown
I suspect that the head gasket is not under the proper tension
IT is very common for people to refit heads without first cleaning out the head stud holes ( thread tap and compressed air)
there is normally water or oil in the hole and as the stud is screwed it it compresses the water/oil and reaches tension by bottoming out on the obstruction but the gasket is not tight

If you are asking the question let a mechanic do it. The gasket is cheap but it involves a lot of work and some experiance. Look in a Chilton book for that model and you'll get an idea of whats necessary.
Possible blown head gasket or rings
. Do compression test.. Possible rebuild or nust head gasket.. But safe to say best to just rebuild when those issues get that bad may get lucky head gasket but most cases it fill rebuild.. But cheap and not that hard to do if you do your self alot book on famous 5.0 motors and alot poeple know how to repair or get jimk yard engine in while you rebuild yours.. Very easy rebuild under 1,000 for renuk5 kit amd jink yard engine.. Jist think how nice when u jave rebuilt engine in that stang... Be worth it. It always is...
unfortunately, even if it is a bad repair shop, it is normal. if the head gasket is blown, then oil and coolant, which are the two important fluids escape the engine quickly, causing damage to the whole motor. the best route to take would either have been rebuilding the motor, or getting a used one. like i said, the whole motor gets damaged, and even in trying to replace only the damaged parts, it is nearly impossible to get all of them without simply rebuilding the motor, so your best step would be a rebuild. i hope this helps. goodluck
Ok, You are going to have to rebuild the motor that is a given. There are several possible problems that could cause this. Blown head gasket, Cracked Head, Cracked Block, a hole rubbed in the timing chain cover if a timing chain guide came free. I had a Nissan do this. A couple of the holes that the retaining bolts go in for the timing chain guide open directly into a water channel and were letting Anti Freeze run free as well as a hole being ground into the aluminum cover over the timing chain by the chain flopping around. You won't know until you open it up and inspect everything.
Well, the good news is this could be something as simple as a blown head gasket. The bad news is most likely that is not the case. You have either cracked your block, cracked the head, worn a hole in your timing chain cover that is allowing the water and oil to mix or blown your head gasket or a combination of these problems. Your choices are to pull everything apart and magna Flux the Engine block and heads or replace the motor, assuming the issue isn't a hole worn in the timing chain cover, or replacing the motor, the easiest of the solutions although not the cheapest. A decent short block should run around $600 to $1000 with shipping. It's used but has been checked and should serve you for a while. The other option is rebuilding the motor. Should you choose to rebuild the motor I recommend you get the Haynes or Chilton's repair manual on your vehicle for doing the job.
Don't try to start the car anymore! You have blown your head gasket. Take the car to a mechanic and have them check the engine out to make sure you haven't done any further damage to the piston. If not, have them replace the head gasket and you should be good. Hopefully it's just the head gasket and you don't need to rebuild the motor. Hope this helps. Thanks for an honest rating and for using FixYa.
The conventional wisdom is that this is a possibility with high mileage engines. But the option of just rebuilding the head versus the entire engine would make the choice easy for me -- I'd rebuild the head... I would say the probability that a new head would damage the engine is kinda low.
the reason it getting hot when stopped is the fan relay is out thus not turning the cooling fan on,this is a time consuming job,the relay is located on the passenger side tip of the frame behind the headlight,the grill,headlights,bumper,and tip of the front fender has to be loosened up to get to it.
The relay is about 70.00 or so,the engine cools down when you drive as you are forcing air through the radiator to cool it down,as for the heater issue probably caused by boiling the anti freeze out ,
To make sure the engine is ok do a compression check to verify the headgasket and heads are ok,as for smelling the sweet smell which is antifreeze probably due to overheating and pushing the fluid out of the cap or tank.
