Ok, here is some recent history..

I was in Germany for 3 yrs with it. I just had the brake system and u-joints replaced and bought new tires.

I have an exhaust leak at the manifolds from both back studs snapped off on both left and right side.

I just had an oil change done. Then a service engine light appeared - code P0301 / Cylinder 1 Misfire Detected - afterwards. The next morning it would not turn over.

I changed my spark plugs for a tune up thinking this could correct the misfire. I got it to turn over by jumping it off.

So now i have a lot of white smoke coming from my exhaust, and on the driveway there is an orange tint from the exhaust, it smells like radiator coolant and it looks and smells like it could me in my oil also.. i looked under the oil cap and it is milky.. there is also evidence of coolant splashed around the tank.

Any ideas? I'm thinking blown head gasket or cracked head or block, maybe?

Blown headgasket and I would check the exhaust valves where the studs are broke to make sure they are not burnt.

I agree with torkum. The white smoke which is most likely steam and the smell of antifreeze are big hints. The orange you are seeing is probably rust from the exhaust system getting washed out with the excess moisture. Also, your observation that you have a milky residue on the underside of your oil cap means you are mixing oil and coolant. Another way to confirm that is to take a drop of oil from your dipstick after you have the engine fully warmed up and touch it to a hot exhaust manifold close to the head. If the oil sizzles its got water in it, if it just smokes ... no water. Check to see if you have a waxy buildup on the underside of your radiator cap also, that will tell you if youve got oil in your cooling system which might be an issue with an automatic trans. My guess is cracked head or blown head gasket.

Well, now i'm deciding if i should just do a motor swap or pull motor and change blown headgaskets. None the less, i need a new fly-wheel and new headers wouldn't hurt. I have to remove the broken studs anyways. I appreciate the second opinions. How much you think it would cost me to have the blown head gaskets repaired? or an engine swap? Any idea?

Looking for any suggestions!

just to get the head redone its probably going to cost $1000.00 or thats what it costs at my local engine shop thats not the removal of the motor or the new gasket or anything just the head replanned

Good old Bill

$1,000.00 to have a head surfaced, find a new shop for your machining. I have to have misread the post.

Head resurfacing should cost around $35-$50 per head that you bring in. If you're paying much more than that, its time to find another shop.
