I am a fairly good shade tree mechanic and I have a great deal of experience building engines however I REALLY don’t want to have to do this job (pull head, pistons, etc.). Additionally I’ve read that the Toyota 2.4L engines used in the Camry have a common problem with stripping the head bolt threads in the block when removing the cylinder head. This really makes the job unattractive.
So – my question to Barryman is which of your products is best suited for I guess what is called a cylinder soak ?
Yesterday I actually purchased a gallon of Chem Dip off Amazon but then today read on your Q&A section that the B-12 product works better for a cylinder soak.
Here is what I found on your site:
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, Berryman B-12 Chemtool Fuel System Cleaner (part #0116) is ideal for your application and you’re on the right track with your methodology. To use 0116 for a cylinder soak, pull the plugs, 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
So what I don’t understand is the statement = “lack of combustibility and their incompatibility with motor oil”
From what I’ve read on the Internet the Chem Dip product is VERY strong and good at removing carbon deposits. I just don’t understand what is meant by the lack of combustibility – I planned on soaking for a few hours then removing the Chem Dip from the cylinders using a pump then repeating the process several times. The Chem Dip that drips into the oil will be removed at the end when I drain the oil before restarting the engine after the cylinder soak process.
This being said how do you recommend I approach this ? Should I cancel my order of Chem Dip from Amazon and place a new order for a gallon of B-12?
This is a very common problem and I am sure that there are lots of Toyota owners that would benefit from a successful outcome using your products. I would love to be your “poster boy” for this common problem.

Instead, part #s 0101 and 0116 are idea for cylinder soaks to unstick compression rings. If you want to address gummed-up oil control rings, you can use the same product in the oil at 1 1/2 to 2 oz per quart of oil capacity.
If you would like to use B-12 Chemtool as an engine flush, pour into your cold crankcase approximately 1½-2 oz of B-12 Chemtool per quart of oil capacity. For a vehicle that holds 8 quarts of oil, you should use 12-16 oz. of B-12 Chemtool. After you’ve added it to your cold engine oil, start the vehicle and run it at idle 10-15 minutes or until the oil is warm. Then change the spent oil and replace the oil filter.
