Instructions
These are few steps to repair an engine block. If your engine block is cracked use the hammer/torque wrench to place the metal stitch in the crack and follow the steps included in the kit to seal the crack thoroughly. Some persons opt to weld the crack rather than metal stitching it but welding is not as effective and is likely to result in problems later on. Metal stitching is a safer option.
If you are hearing a noise and see signs of low oil pressure the problem can be the bearings in the engine block. When replacing the bearings make sure they fit the crank journal size. Typically the size can be seen on the backside of the bearing shell. Prior to replacing the bearings ensure that the crank is straight and does not have to be turned.
If there is black smoke coming out your tailpipe, low oil pressure or a knocking sound in the engine, the problem may be the rings. Buy the rings needed for your particular vehicle and install them. Clean the cylinder and apply a light coating of oil to permit the pistons and rings to move freely.
Another thing that might be causing problems in your engine block is the timing belt and chains. These items should be changed about every 60,000 miles as age is usually what causes them to break or stretch and they may lead to fatal engine problems. If your car is starting and running rough this may be a symptom of issues with the timing belt and chains. You can check the timing belt by testing it with your hand to see if it is loose or broken. If you replace the chains a new crankshaft seal must be installed with the replacement chain.
If engine power is your problem the reason may be that the cams and lifters need repair and oil is leaking into areas of the engine where it shouldn’t be. When changing the cams make sure you get the right cam for your specific vehicle as using the wrong cam may cause the engine to overheat. You must replace the lifter anytime you change the cam for optimal running.
Tips and Warnings
Some metal stitching kits will tell you to apply epoxy/sealant with the metal stitching.
It is of vital importance that you thoroughly lubricate the bearings before installing them. Installing them dry may cause them to seize up when the engine is started and this can lead to additional damage to the engine.
