I have a 66 Mustang with a 302 and I believe that I have a cracked head. Someone told me it might be a cracked block but I don't think it shows the signs of one. There is oil in the coolant, but no coolant in the oil. There is no white smoke coming out of the exhaust. There is no foaming or bubbling coming from the block. Is it still possible for it to be a cracked block because I am kind of paranoid that it might be. I am planning on replacing the heads within the next week and I wont drive it until I do.

If it is an auto, I would be looking first into the tranny cooler in the radaitor leaking, If it isn't I would tear the motor all the way down to find the problem. A machine shop can magna-flux the motor to find small hair line cracks.

It's very likely you have a bad head gasket. You may have a cracked head (possibly 2 if it's a V6) but it's less likely the block is cracked. You have to remove the cylinder head(s) to replace the gaskets. You will then send the heads to a machine shop for inspection and resurfacing. It's at that point you will be told if the head(s) are cracked. If there is a cracked head, you will have to pay for a weld repair or a replacement core to rebuild. With the heads off, you can inspect the top of the block for any indications of cracks or other damage. While the only sure way to check the block for cracks is complete disassembly and have the block magnetically inspected, most mechanics will just consider the extent of the original problem (overheating only, no knocking or oil supply problems) and be satisfied if the block passes a visual inspection. Your first mechanic wanted to cover all possible bases and repair the car in a way that he could stand behind and would give you the best service in the long run. Sadly, that's not the best answer for someone who can't afford to go down that road. You will have to do some leg work, but if you have a 4 cylinder, you should be able to find a shop that can replace a cracked cylinder head for under $1500. A V6 would be closer to $2000. Just remember that there is no way to know for sure what you will need until the head is off the car so you will have to commit to a few hundred bucks to tear down and inspect, but that labor will go towards your total repair. One other option is to install a used engine. This can cost less than half the price of a re-man engine, but usually just have a 90 day warranty. Good luck!

Although it could be a cracked head or block it is most likely a head gasket unless the engine froze and busted. If it froze the coolant should have came to the outside instead of mixing with oil.

yes you have a problem. honestly you better pull the heads off and clean and wash them and look for cracks.Beings there no white smoke is good so maybe heads are ok. oil in the coolant makes me kinda think so Have you checked your head gaskets,?but then no whits smoke kinda looks good for no cracks. sorry Iam trying to help. Heck tear the darn thing apart and be safe.Let me know !

<>More likely it is a leaking head gasket, unless it is known that the engine was run overheated for a long time. Try re-torquing the head gasket first to see if it stops the leak. If so, replace the gasket. If not, pull the head and send it out to be checked. You might still get away with just a new head gasket.

Needs head gasket's. The heads and block's are believe it or not hard to crack. They are very strong and takes allot of HP to crack the block and the heads only crack when you're engine really I mean extremelly over heats. Takes allot of heat to crack a 289 302 or 351 head.

Its a blown head gasket,you can fix it , but it just won't have the same power. YOU NEED TO REBUILD! A 66 Mustang is worth every penny you put in it. Thats when cars were cars and men were men.

it's not a head gasket or cracked head thats not the sign for a problem in that case I'm sorry to say that it is most diffently the block being cracked.

A cracked block would result in water in the oil.
