In the past we have sold two different types of oil lines. They were known as Type 1 or Type 2, and it was too easy to get confused as to the type needed due to various model differences across the years. To solve this problem, we developed a new oil feed line that includes the parts for both Type 1 and Type 2 cars. The installation instructions below will show which parts to use based on which type of car you have, which is why we are still using the Type 1 and 2 designators.
Type 1 - Type 1 instructions are to be used if at the oil feed location off the back of the head only feeds the turbo. See the diagram on the right below, if you have that type of oil line you will use the Type 1 instructions. This was formerly known as an non-AVCS line.
Type 2 - Type 2 instructions are to be used if at the oil feed location off the head splits and feeds the turbo and the AVCS solenoid. See the diagram on the left below, if you have that type of oil line you will use Type 2 instructions. This was formerly known as the AVCS Line.
