Changing springs at home?

How hard is it? I have changed many gasser spings. I understand there is a special tool? Is the job intermediate or slightly above level work?

Are you talking about the front coils or the rear leaf springs?

I think he is talking about Valve springs..

If so. The job is not to bad at all. There is a special tool to use that compress all 4 springs at once.

You must remove injectors to do so and once you have them all removed just take something like a coat hanger (make sure to cut it long eunf so that it wont fall all the way into the Cyl) put in to to a cyl via injector hole and rotate the motor till that cyl is on TDC this way the valves wont fall into the cyl, Then just use the tool and chang the springs just like any other spring.

That is an awsome tool. When you release it to put the new springs in how are the valves held in place?

You DO have to be at TDC for the cylinder your working on. rotating engine 120* each time allows you to work on 2 cylinders for each position. Just do the math.

yes there is, but the injectors need to come out anyway to use the spring compressor.
