I found them under that panel on top of the engine too, but the panel is a biatch to get off without taking all the stuff above it off first. I basically unscrewed it but couldn't get the panel out because of everything else in the way.

Is there a quick way to get at the plugs or do I really have to take all the plenum hoses and stuff off first? This is going to be a big job just to *check* the condition of my plugs.

Boxhead, can you let us know how much the mechanic charged extra for changing the plugs? I wanna know if it's worth the effort of doing it myself :D

Only takes about 30 mins to take everything off, change the plugs and put it all back together again.

I did mine recently. Pretty easy really.

Disconnect the BOV from the return hose, losen off the hose clamps and take off the intake pipe that goes over the top, from memory you have to take off a couple of other hoses as well but it is nothing tricky, just remember where it came from and put it back there after.

Then you have a few bolts to get the black panel out. Under that you have the coil packs, they should be on brackets in groups of three. Disconnect the cables going to them and pull the, out, be careful with then as I have heard that they are fragile.

and hey presto there's your plugs!!

Give the intake pipe and the rocker covers a quick clean and polish while you have it all in pieces, only takes a few minutes.

its exactly the same if it is NA just you don't have to bother with the BOV return pipe. the only reason you disconnect it is because the BOV is attached to the intake pipe that goes over the engine and you need to take that off :D

I had major problems with spark plugs not so long ago so i consider myself an expert at getting to the suckers.

I am able to get everything off and plugs out in around 15mins.

It really is easy.

Don't stuff around trying to get around the cross-over intake piping just undo the clamp pull off a couple of vacuum hoses undo the bov return pipe rubber hose clamp and fling the intake piping to 90degree's then undo the Ignitor thingo majig (black square thing at the back of the motor) and then use an allen key to take the plate off.

No skinned knuckles like the other VS V8 I had.

I prefer to do the plugs on this motor than all of the other cars I have owned.

250 TE 4 Speed Cortina

VL 3ltr 5 Speed Commodore

VS V8 5 Speed Commodore

It really is very easy. Grab a cold bear and start to pull things off with the radio going :D

30mins max :( In and out.

Just when you disconnect the cables, the coil packs are on the metal brackets bolted on, do you unscrew the bolts of the brakets or the screws on the coil packs???

And do you just pull them off the plugs or what?

Thanks

RedLineGTR, the coilpacks are held in by small bolts. There are 4 holes on each mounting bracket, but mine were only held on by 2 bolts each. I don't know if this is like that from the factory or if the previous owner CBF'd putting all 4 back in. Two on thediagonally opposite corners is more than enough anyway.

Once the bolts are out, gently pull the coil pack up and off the plug. It's held on by a rubber moulding similar to what holds normal leads on plugs. You should probably unplug the wire from it before doing this, but in the interests of minimising the amout of stuff removed I left each coil pack hang there off the wire, doing one at a time.

      Fuel Filter replacement

      By GTSBoy · Posted

      What's wrong with the OEM filter. They do the job perfectly. As to your actual problems. Stop driving the. Take it to a mechanic. If you actually do have a fuel delivery limitation and you are putting it under load, you could be killing it.

      ER34 AT ECU and HKS SLD pins

      By Duncan · Posted

      I don't know the answer, but my uneducated guess is this will not work (or, not as you want it to). I would wire the SLD into VSS1, I bet that is what the limiter uses However, I also bet the ECU compares VSS1 and VSS2 and throws and error if they are different. Best suggestion I can make is wire it into VSS1 and see how you go, I guess the error will only appear above 180 when then SLD is active. If it appears at lower speeds put a switch into the SLD earth (or power supply) and only turn it on when you need to go over 180.

      Fuel Filter replacement

      By Diomedes_ · Posted

      Hi all, So, looking to do some general maintenance on the car, as it has developed a some slight (related?) problems; Three problems that I think are related. 1999 R34 GTR RB26 - engine will sometimes cut out while left on idle, but will keep going if I keep throttle input. Usually after having driven a while. Its random, somedays wont happen at all, others will happen once or twice in a half hour drive. - Second issue is that while driving, the car will sometimes not be able to get past 3k rpm, no matter how much throttle input I apply. - Lastly, car will sometimes be real laggy climbing through rpm, but if I apply lots of throttle problem will seem to clear and go back to normal. All issues come and go, again somedays no sign of any problem, other days will just be stuttering around for ages.   I think it might be either the fuel system, or maybe the AFM?   Either way, I am going to clean the AFMs, and replace the fuel filter, use some injector cleaner in the next few fill ups, and might look at doing the fuel pump aswell.   Question I have, is filter such as; https://www.efisolutions.com.au/pro-fuel-filter-30-micron-an8-orb-black Fine to replace the normal filter? Their product page says as a prefilter only and not as the main EFI filter, so I'm guessing I would still need the stock one? Can I get an aftermarket one that has AN8 fittings to replace the OEM one? Or is the OEM one just something you have to live with?

      I say this and there’s a Nistune r34 GTT MT ECU for sale on eBay.de but I need to figure out compatibility between the AT harness and MT ECU - TCS considered. I figure this HKS SLD is a quick bandaid anyhow.
