replacing spark plugs in a MY01

Postby xcwizit » Fri Mar 30, 2007 2:49 pm

hey guys,
I have had my MY01 for 2 weeks so still new to the subaru cars. My car jerks /jolts on second gear a few times and also when I'm at high revs around 4000-5000 RPM. I'm thinking it's the spark plugs..

So I have bought new spark plugs ( BKR7E, 0.8mm gap ). Hopefuly this will fix the problem

Just a few questions. WHERE DA HELL ARE THE SPARK PLUGS LOCATED?
i have taken off the TMIC since i was told they were underneath but still cant seem to find the sprk plugs nor the leads.

Doesn't state in the manual where the spark plugs are located, but how to change them. Manual is no help. You'd think they would state EVERY lil THING in the manual, i used to own a EK1 96 Civic and i must admit Honda Manuals are alot more better to understand and contain a hell lot of info than Subaru manuals.

finally, would my AFM be the cause of my MY01 jerking at high revs when I give medium throttle? Bare in mind, I have a Blitz Air Pod.

CHEERS GUYS

They are an extremly difficult thing to change and at the risk of some members here who have an issue with somebody referring another to a mechanic I would suggest taking it to perhaps URD.

I had a mechanic mate and his brother (subaru mech) help with mine and it still took us near enough to an hour, trust me they are not for the feint of heart!!

You need to remove the washer bottle and the air box to get to them for a start.

On my car (MY00) took around 1-2 hours the first time.

It always helps to have the right tools as this saves lots of time and frustration. I had to remove the water thing from the car to change mine.

I too will risk upsetting people and also reccomend taking it to URD. I've changed the plugs before, and its a real sh1t of a job and it took me nearly 2 hours. Getting someone to do it who does it there sleep (like Tony @ URD) is the smart option.

Still if you want to try it yourself, you need to remove the airbox on the drivers side and the windscreen washer bottle to make it a little easier to get access to the plugs. Also be prepared to loose some skin and even a little claret.

The usual tools will be needed, sockets, ratchets, band-aids.

Remember you have a boxer engine now.... the cylinders are horizontal, and the spark plugs are at the ends of the cylinders.

plugs are alright - it's a crappy job but I can think of worse :D

Basically - remove the airbox off the drivers side and remove the water bottle out of the other. I use a Kinchrome spark plug socket (magnetic) and a 3" extension. Remove the plug lead off the plug you're working on - (if you've got some comressed air give the plug hole a clean now) stick the socket and extension down the hole till it locates on the plug, then put the socket handle on and undo. Put the new plug in the end of the socket (no handle) and feed it into the hole - then do it up by hand making sure not to strip the threads (you can put some anti seize on the threads if you want) until you feel it hit against the block. Then put the socket handle on and tighten an extra half a turn. You can also use a bit of hose on the end of the plug instead of the socket - this is meant to be better to save the threads but I find I have more control with the socket. Repeat this four times and put everything back together.

SWEET SWEET DONE EVERYTHING

ALL THAT'S REMAINING IS 1 FUKN SPARK PLUG
The 3 other spark plugs are easy to change. No harm done.... Its just the 1 on the drivers side, closest 2 firewall, thats the hardest

I've turned the bolt that holds the coil so much... that its' lost its shape/form. even my 12mm socket has lost its shape inside.

How do I take out the last remaining bolt with it being out of shape?
how do i overcome this problem

ummmm...... now that's a nasty one to have rounded - can you get a set of vice grips on it? Is there any shape left to it at all?

I would actually say its the quality of the tools involved thats caused the problem not poor workmanship.xcwizit said his socket is out of shape now so, I would say its some POS and thats were his problem has started from.

yeah - probably very right regarding the tool quality if you can stretch it on a coilpack bolt.

actualy for sum miraculous reason, haha, i used a 12mm socket i had laying around and it worked.

All spark plugs are changed by myself, no need for a mechanic.
1problem though....
There is now a KNOCKING NOISE on the left hand side of the engine bay (passenger side)
I dont quite know where its coming from, all i know is that it wasnt there before i changed the spark plugs...

Any sugestions....

Now do you understand what I meant by a pain in the arse job!!

Check that all of the coil pack brackets are fitted correctly.

Hey,

Did you make sure that the coil pack signal wires went back on properly and that you didn’t by chance reverse them when reconnecting? The rule is: ‘black goes to the back’.

Also, if you would please do us a favour and not use SMS-speak/abbreviations on the forum.
Firstly, it’s not cool and secondly, we’re not all 16 years old! You’re not limited to 160 characters of text here! So feel free to write as much as you want.

Hope you fix your noise. Is the car running ok otherwise? Did you fix the stumble?

Cheers mate,
