changing spark plugs>>H6

[1stgenfarmboy]

i changed the plugs in my H6 last night, WOW what a poor design flaw.


is there any tips to make this job go alittle faster than 3 hours.

no.

but if you think that was hard, you should try replacing the valve cover gaskets. the rear bottom bolt on each side is a real b1tch.

Yes. On the driver side, take the battery and washer reservoir out. This makes room to remove the coils.

On the pass side, its just a tight fit. Really nothing you can move out of the way. You could remove the one engine mount nut on that side and jack the motor up as his will help clear the body rail.

I wish I could have done it in only 3 hours the first time.

I had to use a length of wood and my floor jack to push the engine up a little to re-install the DS rear coil.

'wobble' plug socket and 'wobble' extensions help get the tools in/out.

One major one--do them from the bottom. I can't imagine trying it from the top, just don't see how that could possibly be easier.

Otherwise, here's what I learned when I was changing mine: H6 Plug Change: Not quite as bad as it is hyped to be.

with the valve cover gaskets off it's much easier. i did mine when the valve cover gaskets were off and it was actually easy from underneath.

will do my other one soon too and will replace the valve cover gaskets as well.

it's not a design flaw either - cars are not designed with your comfort level or ease of maintenance in mind....no one purchases that way so dealers would be silly to design as such.

note - there are quite a few vehicles (no subarus) that require the engine to be lifted to replace the spark plugs (all the ones I know of are American vehicles). now that is a bit much for me....but only because i'm used to Subaru's.

Or Ford F series where the rear of the engine sits under the cowl and you can barely fit a hand in to clean an IAC, or having to replace a forward O2 sensor and the harness plug is midway between the top of the head and exhaust with 1.5 inches between the engine and firewall. Still can't figure that one out except it saved a few bucks a truck in harness cost. So some manufacturers don't even consider replacement of maintenance items in their design.

Subaru is an easier vehicle to work on compared to others. You just don't have other vehicles to compare it with.

Oh yeah i did it from the bottom, On the pass side i did put a small port-a-power between the engine and frame and moved it over about 1 inch, that help alot, as well as all the corect tools, i just didn't want to unhook the motor mounts to raise it up, although i probly will the next time.

i think maybe raise it up and scoot it over mite be the way to go.

Kind of like doing that 6th injector on your Dodge...some jobs are a pain.
I have an 06 3500 Ram in the fleet.

My 6th injector is easier to get to than yours.







but there are things that are a pain on everything i guess.

just never thought it would ever take me 3 hours to change plugs...
