Can we use this chemical to soak by pouring into the combustion spaces of a diesel engine through the injector port. allowing to soak for limited time.
Will it release stuck piston rings in grooves while within the cylinder liner.
The Engine is a 1000 HP Diesel Maine engine.
Neither of the Berryman Chem-Dip products (0905 and 0996) are suitable for a cylinder soak because of the lack of combustibility and their incompatibility with motor oil. However, you can use Berryman B-12 Chemtool Fuel System Cleaner (part #0116) for a cylinder soak in order to free stuck rings. However, if the oil rings aren’t sealing well, then you run the risk introducing a fair amount of solvent into the crankcase. To use 0116 for a cylinder soak, pull the injectors, put 0116 in each cylinder, let the product soak for 30 minutes to 2 hours, and then remove the mixture from each cylinder. Repeat as necessary.
If you have a V-configured motor, then it may take nearly a full bottle of 0116 per cylinder to ensure that you cover the entire compression ring, especially if that ring is stuck and allows some of the B-12 Chemtool to migrate toward or into the crankcase. However, if you don’t mind soaking one side at a time, you may be able to raise one side to flatten that bank of cylinders and thereby cut the amount of product required. You can also buy Berryman B-12 Chemtool Fuel System Cleaner in a 1-gallon size. That part number is 0101. Best of luck!
