Default Changing cyl #4 spark plug on EJ257 swap into GC8

There's about 2 inches of clearance from valve cover to chassis for cylinder 4 (closest to firewall driver's side). I even had to detach the rubber boot/spring from the coil pack in order to find room to remove. However, putting the boot back into the coil became a great challenge. Also, I wasn't able to pull this spark plug out because my ratchet was too fat when I used a 3" extension. What kind of tool did you guys use in order to pull this spark plug out? An extended 5/8" spark plug wobble?

A mechanic said I may need to drop the motor mounts.

i had to use the 3" ext. and a different ratchet(with diff. fatness) than i usually used, but had enough room w/o undoing the mounts. if you don't have any other ratches or wobble extensions to try, loosen the motor mount bolts and push the engine to the side. i had done that to my sisters H6 legacy once.

Thanks Keith for the pointers and advice. Went to the local auto store to get a wobbly spark plug bit and a thin profile ratchet (breaker bar type). Extracted the spark plug using both and pulled the stuck rubber coil boot from the spark plug with 90 degree pliers and re-seated it back into the coil pack.

Tools:
3/8th inch breaker bar
3/8th inch ratchet
3/8th 5/8th spark plug bit
3/8th 3 inch extension
3/8th 5/8th wobbly spark plug bit
90 degree 11 inch pliers

granted, I have a 2.0 in an 03, but I pull the intercooler, dog bone brace thing (sorry, its past my bed time), the 2 nuts for the motor mounts on the crossmember and jack up the whole motor. I usually pull out the battery and the washer fluid res too. All and all, it takes me about an hour to change all 4 plugs. I don't know if the GC has different frame rails, but this method works really good on my car. Good luck.


Edit. you should always remove the pitch stop (i think thats what its called) when you move the motor around, you can break your windshield... Try this method though, suprizing simple and quick.

lol, you newbies crack me up.

All you need to do is get a 3 inch extension with a slim ratchet, unhook the battery and washer reservoir, unhook the maf intake if need be. Unbolt the coilpacks, twist them 180 degrees and pull them out, put your socket with extension in the hole to put it on the spark plug, loosen the plug with ratchet, use fingers and extension to get the plug all the way out.

+1 for this the plugs arnt that hard to get to. If you have to jack the engine up you're doing it wrong. Well not wrong but you're definitely wasting time.

Glad you got it done! Some cars have more room than others, and sometimes you're balls deep before you realize you need a different ratchet or whatever. Those pliers look mighty useful!

Some cars have different tolerances and dont have the same amount of room fyi. i told him to find a dif. tool combo, which typically does the trick. I only had to jack the h6 up once, it wasn't perfectly aligned, and was better after centered. These have less room than the dohc engines. Your newbie comments arent helping anyone, so just stop commenting if you have nothing to actually contribute to his situation. You are a reason people hate nasioc in general.

oh im sorry i didnt realize changing plugs on an "ej257 swap into gc8" had anything to do with your h6 legacy.

i dont know if you noticed but i quoted and +1'd a post. A post which states the EASIEST way to change the plugs in the OPs situation. move washer tank. move battery. move intake. thats all you need to do.

i wasnt being a douche by attacking someone to inflate the thread with bull**** posts such as this one as well as yours. i simply stated jacking the engine up is wasting time, which is true.

I also spoke of dohc heads in a gc8. if his particular car and engine had less clearance, like the H6 does, it may require more than moving the washer tank. Moving the engine would be a last resort. I think you need manners, and you were being a douchebag btw. And you did inflate your post count, while cluttering up his thread. Your reading comprehension is poor fyi

before i entered this thread you spoke of trying a different tool or moving the engine. i said dont move the engine, its a waste of time. which it is. you then attack me out of nowhere.


yet im a dick.


and yes. you did speak of dohc engines. you said they have more clearance than an h6.


oh wait thats my whole point. he has more clearance than you did, you know what that means? that means its unnecessary to jack up the engine.

having the correct set of tools is the right answer to his issue. and yes i know you did make that suggestion.

it was that suggestion helped him solve his issue, which is why i didnt touch anything earlier in the thread. the problem he had was solved. the only point of my post was - once again - to state that jacking is a waste of time. some people actually use the search function. my post was geared towards them as a reinforcement of what NOT to do.


maybe youre already heated from reading a bunch of bull**** posts today and mine somehow set you off. sure i could have added more to my post but i usually like to get right to my point. im sorry if thats a problem with you. have a nice day.

in the OPs case jacking up the engine is an unnecessary waste of time.

I only read your post yesterday! Lol. You said dont move the engine, a waste of time. If he has to move move it, say its night and stores are closed and no other tools are avail and he has to drive to work, then your obvious comment of doing it by the books isnt doing him any good! He would then have to get creative and do "something" else, which is not a waste of time. He already got to cyl 4, so he obviously not incapable of realizing he needs a diff tool at that point. You stating the usual way got him nowhere, typically i'd call you captain obvious for that response. So how exactly did you telling him that help? I fail to see your help in the matter, truly. Its not always by the books guy. I dont want to respond to this due to clutter, but really want to clear this up. My sisters h6 had to be slid over once, and thats easier than raising it, or the 4cyl engine. That is the next easier way, when by the books doesnt cut it, due to whatever reason. Just because his 4cyl has more room than the 6cyl, doesn't mean he has the room needed, you assumed that! So you had no point, as you stated. Dont assume, you're not there, and that won't help him. I stand by the fact your post was unnecessary, however good your intentions were. I wasnt being a dick, just tired of useless responses. Your skin is too thin, ego too big, and knowledge too shallow for real insightful help here...

In my humbleness I concede. I now see myself through your eyes. I see how I am incompetent, ignorant, and have an ego bigger than that of uncle scotty himself.

Please forgive me for my ego driven original post. Supporting somebody else's insight (*that of which ive personally used on my old dohc '98 2.5rs*) on the subject at hand was completely absurd, wreckless, and above all uninformed on my part.
