There are many who have attempted to repair cracked blocks. The main difficult is that you cannot simply weld an engine block since it is made from cast iron, not steel. It is possible to weld cast iron using an arc welder and the proper welding rods, but that often can cause deformation to your engine block, or leave the welded area far more brittle and susceptible to further cracking. The other common attempt at fixing a cracked block is called cold metal stitching. This process is similar to sewing two pieces of fabric together, except it is far more difficult with metal. The main difficulty with this process is that it does not work well on components that experience drastic temperature changes as the temperature change causes swelling and shrinking of the metal which will cause the metal stitching to tear and the crack to reopen. This process is also often prohibitively expensive and only used on very large or expensive motors such as heavy equipment, diesel engines or marine motors.
Before you attempt any repair on your cracked engine block, you want to be sure that is the problem you have. If you have an external crack in your block that you can see, then the problem is easily identified. If you have an internal crack the symptoms can often be similar to that of a blown head gasket. To determine if you have a blown head gasket, you can read our article about the symptoms of a blown head gasket.
I used Blue Devil, on an 84 Buick 5.7 Diesel Engine that had either a cracked block or a blown head gasket, and it worked very well. Sealed the leak successfully and was very happy with the product. Company Technicians were very helpful and very interested in solving my problem. Wished I still had that vehicle, as it was an Estate Wagon, pretty rare with the Diesel engine !!
Thanks for your question about your leak. Even if you do not have coolant in the oil or out of the exhaust you may still have a small coolant leak either from a blown head gasket or a cracked cylinder head. If you had water in your oil you could be losing compression due to corrosion of the cylinder walls or cylinder rings as well as a crack in your head, block or a partially blown head gasket. Unfortunately, to confirm any of these things you would have to tear down your engine to check.
hi i have a Peugeot 405 1800cc fuel(petrol) injection engine its block cracked is helpful your products for repair it , please tell me about how use and how much use thanks a lot
I have a marine motor. My Uncle left water in the engine and it cracked. There is a visible crack on the outside and the oil is milky. Im assuming that it is cracked on the inside as well. From what I am reading this will help. My uncle mentioned that it was overheating so would this seal before overheating and filling the oil with water?
Hello, Hello, My Name is Derek, I am from Nome Alaska. I have a 1991 Ford explorer. It shows roughly 75,XXX miles on it. Of course it resets after a 100,000. Anyways I bought this car this summer and i put about 6,000 miles on it, and the clutch went out, so i replaced it. After that the car started burning coolant out the exhaust, like a lot. So I stripped the car down to the block to check the head gaskets and realized the passenger side gasket was blown, and I replaced the driver side head cylinder. I didnt replace the passenger side. I should have replaced both sides at the time but just the driver side. Anyways after replacing gaskets and driver side cylinder the same problem happened within two weeks or so. So yesterday i finally had time to strip it down and took both heads off and the new head is fine, the passenger side head tho is cracked between the exhaust valves and they are leaking so I ordered a new head for the passenger side. but once back together and if i have the same problem i swear it would be internally on the engine block which i am afraid of it might be. Would this product work if the leak is internally on my engine block?!? Please let me know. Thank you
The BlueDevil Pour-N-Go Head Gasket Sealer would seal a cracked engine block as well as a heater core leak. There would not be any need to use both products. Feel free to contact our technical support line at 888-863-0426 with any other questions.
Hello, I have a 2007 honda civic lx with 70K on it. I purchased it used less than a year ago. The other morning I notice coolant fluid on the ground.Drove it to get checked out and they discovered a hairline cracked toward the front of the engine block. This is a known manufacturers defect but my car is out of the ext. warranty period. Blue Devil radiator n block pour n go was suggested as a possible fix or temporary fix. I did use it and it seemed to lessen the leak but not stop it completely. The car ran for over 300 miles with no overheating but their is still a slower leak. Is a second bottle of Blue Devil radiator & block pour n go recommended or can a second bottle do more harm than good? 2b1af7f3a8
