Best Way To Clean Exhaust Ports

Never use a carbide burr in the combustion chamber they are much too aggressive and will remove too much metal.

Best way to clean exhaust ports. Close the valves by rotating the cam 180 degrees. Your turbo may have a port in turbo very near the turbine speed sensor. Start by spraying the cleaner into the port.

Once the powertune has sat on the carbon for awhile it softens it up to a putty like consistancy. I apply a thin bead to both sides of a new exhaust gasket or depending on the engine application apply a bead around all exhaust ports without the use of a mechanical gasket. Take a good new intake gasket and attach it to the head loosely with a couple of bolts.

I believe the plug is a 316 inch pipe plug. Spray some solvent on the bolts which are on manifold heat shield and then remove them. Continue this until you can spray cleaner all the way through the passageway.

The dealer has a method of running turbo in shop that might clean as well. Its on valve overlap. Once it is roughed out use progressively finer polishing wheels to smooth out any rough edges.

To clean a valve you need to remove it from the cylinder head and that always means removal of the cylinder head. Before you get started you will need some parts supplies and two custom made tools. Pour about 8 ounces of engine cleaner -- about half the standard can -- into your plastic bottle or glass jar.

Dump it at the same time that you slam the throttle wide open to get the motor to clean up. These days the cylinder heads is usually topped by the cam boxes so it means those have to be removed as well. It also runs down the exhaust valves but in small amounts.
