The primary purpose of intake valve cleaning is to remove carbon buildup, particularly in Gasoline Direct Injection (GDI) engines, to restore engine performance, fuel efficiency and smooth idle. It prevents issues like engine knocking, misfires, power loss and cold start problems by ensuring proper airflow and fuel combustion.

Our customer reported that this 2.5L naturally aspirated Boxster engine was losing coolant, overheating, steaming and loss of power. Our diagnostics showed that it had breached/blown head gaskets. We ended up removing and rebuilding the entire engine. Rebuilt the heads as well. Installed new multi layer steel head gaskets (the Subaru issue is the head gaskets are single ply composite gaskets and that is why they are so weak). We then installed a whole new clutch assembly (flywheel, clutch kit, bearing, fork etc.) as well as hydraulic system. We serviced the timing belt and the water pump as well as replacing the front and rear main/crankshaft seals. The vehicle is back on the road, running as good as new!

Getting ready to store this car for the winter, but not before a Battery Test!

2006 Toyota 4Runner in for head gaskets.

We replaced all 4 struts / suspensions and serpentine belt on this 2008 Audi R8 4.2L V8, as well as performed oil change and inspection service.

Here is an intake valve carbon cleaning we performed on a 2012 Audi Q5 2.0T, which has 165,000 kms on it. This is a large cause of misfires. Customer was noticing loss of power, rough idling and misfiring. Carbon buildup is a result of incomplete fuel combustion. This can affect any engine that is direct injection or turbocharged.
