This is the Montana model. Trying to do compression test. Was wondering the easiest way to get to the back three plugs.

Hello,

Yes those are tough on this model. You may need to remove the upper intake manifold so you can get to them easier.

Here is a guide on how to do the compression test for reference.

Please let us know what happens.

Cheers, Ken
