Outer Limits 4x4 Board

Jut got my new ignition leads. Went to put them in. Who designed this freakin engine ?

Any tips for fitting spark plug leads to a EFI 4.2 GQ ? Without disassembling the bloody engine

sounds like fun i was going to do mine next week, maybe not then:)

If you think thats fun, try fitting them to an EF Falcon with coil pack ignition . You could try fitting them with long nose pliers though, or start pulling things off.

you dont have to dissasemble anything? its quite easy, it just looks hard

Looks like you can get to number 4 and 5 due to the inlet manifold. And number 6 appears to be covered by crap hanging off the inlet

I will have a proper go at it tomorrow.

Are you talking about the EFI model ?

Had the same trouble when i was going to gap my plugs. Couldnt be tuffed taking EFI and gas stuff off.

Exactly. Mine is EFI and LPG too.

So what did you do ?

Hope the leads help. Here is what I did.

Get one ten year old son with skinny arms show him what you want done and tell him you will give him five bucks if he gets it on. Pick him up throw him in engine bay the hold on to him really tight so he is nice and steady you have to hold him around the knees. When he has got it on get a pair of long nose pliers to make sure it is tight. Then crack a beer start engine and listen to it purr.
Have fun

Steve

92 Ti Efi Lpg and lots of scraped knuckles.

For such a big vehicle there sure is no room to work on them.

I've got to do the tappets on mine, so I'll give it a birthday and do the plugs and leads while all the LPG stuff is out of the way.
Regards Andrew.

and make sure you take kid out of engine bay before starting or will make a real bad squealing noise.... danm annoying..

and they complain if its hot too!!
now when i was a kid...if i complained....

i think its the same a the tb45? i remember when i first got my GU i took off the plastic cover to see what it looks like underneath and thought fark that. i think il just leave it until one day when im really bored or when it really needs to be done

"So what did you do ?"

Well i found out when the last guy changed the head he used the iridium plugs and i just left them gapped as they were!!

No they aren't. The TB45's are simple. Very good access. It only takes 5 minutes. I have pulled plugs and checked condition , and gaps many times. The TB42 EFI's are a worse design.

Heres a photo of TB45 plug access. Anyone got a pic of TB42 EFI.?

Here is the engine bay in question. Note, this is pre LPG conversion.

You can easily get number 1 and 2. Number 3 is a squeeze. Numbers 4 and 5 are under the intake and number 6 is under the brass coloured cylinder at the back.

Gee thats cean, neat and tidy?????

what about the plugs back near the firewall? i cant remember exactly why i didnt change them when i looked but i remember one or two of them were hard to get to or something? its been a while since ive looked so my memory isnt the best

I use a simple short 1/2" extension with the plug socket and 1/2" sidchrome ratchet. Easy.

that is disgustingly clean

Sorry, the GQ is stock as a rock. It is my daily driver and tow rig for the buggy. It doesnt generally go offroad, unless its to tow the buggy somewhere offroad.

See, if you brought a diesel, none of this would have to happen

Its the same as mine....except yours is a lot cleaner. I did the spark plugs a few weeks ago. Its a bastard and you hurt your knuckles a lot but it can be done. All i undid was the air pipe but not fully, only enough to move it a little bit just to give me just that little bit of extra room needed to do it. And you want a variety of different socket extentions cause each plug needs like a different length one to reach it......sort of. lol

now arent they pretty you dont wanna see mine it dont look that... errrr.... good even after i clean it!

One of Marks mates at Suziworx did it while I was chatting to Mark about my buggy

He took the air pipe off to the manifold and away he went. Took him about 10 minutes

New plugs, leads, oils (gearbox and engine), oil filter, air cleaner, bled brakes and a full LPG tune up (with valve adjustments) have made quite a nice difference to the running of the GQ Totalled just under $430.
