Six Star Triple Layered Head Gaskets

Because, you only want to do the job once!

One of the most common failures on belt driven Subaru's is the head gaskets. From the factory, Subaru utilized a single layer head gasket with a graphite coating. This coating along with the single layer allowed the gasket to leak externally creating an oily mess under the vehicle. While it can be fine to drive the vehicle for thousands of miles in this condition, it can lead to a few causes of engine failure. If left untreated it can increase oil consumption, eventually leading to oil starvation and catastrophic engine failure. When left for long periods of time, the head gasket will deteriorate more which can lead to the engine overheating, which can also lead to catastrophic engine failure. 

Over the last decade we have completed thousands of head gasket repairs and have saved thousands of Subaru's from these engine failures. We have found the right combination of replacement parts that will prevent the head gasket from leaking again throughout the life of the engine. We use a triple layer head gasket, with a better coating that does not deteriorate over time, resurfacing the cylinder head with a reputable machine shop, and an updated torque procedure to resecure the head to the engine, you will never need to replace the gasket again. We also replace the other 32 gaskets on the engine that are more difficult to address with the engine in the vehicle at the time. We also perform a tune up with premium spark plugs, new spark plug wires, a new timing belt kit with water pump, a fresh engine oil change with premium synthetic blend of oil and a new engine oil filter.

On chain driven Subaru's head gasket failure is not as common, however it can still occur. One of the common signs of head gasket failure is coolant mixing into the engine oil. Another sign is the engine overheating, when no other cooling system issues are present. The cause of head gasket failure on chain driven Subaru engines is primarily due to overheating the engine, which then causes the cylinder head to warp. Similar to the belt driven Subaru engines, we replace the head gasket with a factory head gasket from Subaru, take the cylinder heads to a machine shop to have resurfaced, and install the head to the engine using factory specifications. We also complete an engine reseal of important components including camshaft carrier, timing cover, valve cover gaskets, and also install new spark plugs. At this time, we also recommend doing an upper oil pan reseal, as this is a common failure point on this engine and also requires the engine to be removed from the vehicle to be complete. This will ensure you have tens of thousands of miles to enjoy your Subaru.

TIming Belts, Timing Chain & Water Pumps

Subaru timing belts need to be replaced after seven years or 105,000 miles; whichever comes first.  Timing Chains do not require to be changed as often, sometimes they are good for the life of the vehicle.  If you have a question of whether your Subaru has a Timing Belt or Timing Chain, we can answer that for you by giving us a call at 303-733-4544.  As a general rule, all H6 Subaru's are timing chain, all Outbacks 2013 and newer are timing chain regardless of engine size.  Forester started the timing chain engine 2011 and newer and Impreza NA, Crosstrek saw the timing chain introduced in 2012 and newer model cars.  All others can be considered to be timing belt cars.
