Tip: After ten seconds of cleaning, all of the water should be draining out of the exhaust. If water is draining
out of the engine adaptor, check the position of the hose adaptor on the hose.
5.

Do the same for all remaining cylinders.

6.

It is recommended that after cleaning, all single ports
are checked with snap-on boroscope BK6000 (or
similar, with 90-degree lens), to make sure all ports
are clean (Figure 17).

Figure 17. Clean single port.
7.

When all carbon is removed, install a new main port plug using an 8mm socket with a short extension,
paying special attention to install it squarely. The outer edge of the plug should be recessed ~0.5mm – 1mm
behind the outer cylinder head edge.

8.

Reinstall all components (except spark plugs) and fill the system with coolant according to ELSA.

9.

Using a vacuum extractor, remove all water from all combustion chambers.

10. Make sure all water is removed from the combustion chambers by using the self-start function twice
while the spark plugs are still removed (cover spark plug openings with a towel). Install spark plugs and
coils.

Tip: There is no need to replace the engine oil; almost no water drains into the oil pan.
11. Allow the car to run at idle for 15 minutes to ensure that any remaining water in the exhaust system
evaporates.
