Hi everyone. I know this problem could either be bad head gaskets or intake manifold gasket or cracked head. I'm pretty sure this isn't my block. It was recently checked before restoration began on this car. The Intake and Carb. are off as a total piece because I am in the process to remove the Heads and their gaskets. I am going to take my Heads to a local shop to be sure they aren't cracked or warped or anything like that. But before I started removing everything, I drained all the Coolant and contaminated oil. I left all the Coolant out (drained) and refilled it with new oil and I started it up about three times. It starts up. Then leave it for about a day (not touching or doing anything with the car) and go back and check the oil, and it is mixed with antifreeze again (even though I drained all the Coolant). So I figure there is still coolant somewhere that is not coming out when it was drained from the radiator and its hoses and the water pump was also replaced. Then, I took all the Spark Plugs out and they aren't damaged and I turned it over and no water came out of the spark plug holes. But it is still mixing with the oil. Once the Heads are gaskets are off, I am going to soak up as much as I can with a rag and then replace everything and connect everything back up. Then I'm going to drain the oil again and fill it up with new cheap 10W-30 and Engine Flush and let it idle for about 5 minutes and drain it again and hope that will clean everything out. Then refill with the new oil and filter and all that. I'm just wondering if you think soaking up as much coolant as I can and using Engine Flush will get all the coolant out of the spots it's not supposed to be will fix my problem? Thanks in advance.

You can clean the cylinders out with rags once you get the heads off. Look at the gaskets closely. Hopefully you dont have a cracked block. If your heads check out. You may have to pull the block out and have that checked for cracks too. Did you have any real coolant loss in the radiator?

Well I'm pretty sure the Gaskets are blown. It is my project car. It was my father's car. He said that everything on the car was fine but there will be some parts that need to be fixed especially the gaskets. I looked at the Valve cover gaskets and replaced that and that gasket was GONE! It looked terrible so I imagine if that gasket went bad, the others probably are as well. Just like what my dad said. I just wanted to see if the car would start first before I started replacing the gaskets to be sure the whole motor doesn't have to be rebuild. Replaced Distributor, Spark Plugs, Wires, Battery, Starter and fluids. Once the car started, then it started leaking. My dad said: "Yep, that's a blown head gasket for ya." I have been around cars a lot in my life so I'm pretty sure that is what is the problem. I started the car WITHOUT coolant (Started and shut it off - NOT Driven or even idling for over ten second). It is just that there is still coolant somewhere that is mixing with the oil. Smokes white so I figure if I did what Chris said and and clean the Cylinders and use Engine Flush, all the old coolant should get out of there and then put it all back together and it should be ready to roll?

Be sure to check the mating surfaces of the block and heads. While your problem is most likely a blown gasket, it could be warped heads or uneven block surface. I had a silimar problem, but the head gaskets looked good. I found that the heads were slightly warped, so I had them milled 0.010 to clean them up. I haven't had a problem since.

You don't say what size engine you have, but it looks like a complete teardown may be needed to ascertain your problems. Here's hoping for the best.
