Other Services Available

Replace or Reuse Variable Cam Gears (Intake and Exhaust) * 

These often become clogged with debris and/or the alignment pin hole for the cam shaft gets wallowed out and causes excessive variation in timing which often results in a CEL and drive-ability issues. We HIGHLY recommend they be replaced on any rebuild.

Replace or Remove Oil Cooler * 

Some Subarus have an oil cooler that is located on the passenger side in between the oil filter and the cylinder block. Due to their design, they can not be cleaned or flushed and must be either replaced or eliminated. We have them available here or you may source them for yourself or we can simply eliminate it.
