Using Sea Foam Treatment on a Honda Accord 2.2L

Model: Honda Accord MK 5 - Years: 1993, 1994, 1995, 1996, 1997, 1998
Part: Engine

Video tutorial

Let's see how to DIY the Sea Foam treatment on the Accord. This treatment cleans the internal deposits of the engine, depending on where it is inserted.

The video shows the treatment of the valves, the combustion chamber, and the exhaust system. First, locate and disconnect the vacuum hose leading to the brake servo.

Start the engine and slowly introduce the product into the vacuum hose; you will notice the engine revs rise and fall, which is normal. Continue until half a can is emptied.

Once done, turn off the engine and reconnect the vacuum line. Leave the car off for 10-20 minutes.

Start the car and accelerate alternately; you will notice white smoke coming out, indicating that the product is working. Finally, add the remaining half of the product into the tank, allowing you to use the car without issues.

AdBlue Tank Fault on Peugeot 2008

If the instrument cluster of your Peugeot 2008 sends an alarming signal as seen in the video, despite having just filled the AdBlue tank, the problem is not that the tank needs replacing - as authorised workshops simplistically suggest - at a cost of around £1,000. The first thing to do is to remember not to wait for the system to remind you that you are low on AdBlue, but to refill it every 5,000 to 6,000 miles, as the fault lies in the measurement of the tank level. Another good practice is to add an additive (yes, an additive in the additive) such as Tunap 988 (£23.99 on Amazon, with free delivery) which will prevent the AdBlue from crystallising.
