Hi,

This process requires special tooling. You need them to prevent the camshafts from moving and properly setting them.

If you look below, I attached the directions for installation from my manual. Take a look through them and let me know if you have questions,

Take care,

Joe

Hi,

Yes, they have special tools for everything anymore. LOL As far as the phasers are concerned, I attached the directions below for replacing them. The tools needed are indicated.

Let me know if this helps.

Take care,

Joe

Hi,

I'm not sure what you need. Are you talking about the clearance between the pistons and valves? If so, that isn't something I have.

Let me know.

No, I need distance inside the tool itself (number 3 in the photo).
