Any tips for fitting the rear bank plugs? My Magna is just about to hit 100.000klms so I went out and bought a set of six NGK Iridium plugs. Front bank is in and I plan to do the rears tomorrow.

you've got 'the' 100k service, you should get the timing belt changed as well, so I would suggest you to get quotes from dealerships about this big service.

But if you've already done that, than installing the rear bank is quite straight forward, unbolt the intake plenum, (from the front , from the throttle body, and from the back) and Lift up.

that's about it, nothing hard about it.

Not sure I quite understand the first part of your post. I'm doing little things like changing oil, transmission fluid, plugs, etc to try and reduce the cost of the 100.000klms service. I intend to take the car into my local trusted mechanic to get them to change the timing belt and a couple of other things.

Cheers.

you got exactly what I meant.

Well disaster struck.

I very carefully removed the manifold (meticulously noting the location of fasteners, wires, tubes, etc), replaced the plugs, and refitted the manifold. Right at the end I realised that I needed a torque wrench to refit the six manifold fasters. I guess I didn't *need* one, but wanting to do the job right I went out and bought myself one.

Anyway I've never used a torque wrench before and ended up snapping one bolt (it's stuck in the block) and stripped the thread in another bolt hole. To make matters worse I lost the right nut so now the manifold has only 4 of 7 fasteners :cry:

Now getting another nut and washer is easy, but what can I do about the snapped bolt and stripped thread? :shock:

You could try an easy out but it depends on how tight it is in the hole ,this involves drilling ( correct size for ezy out)a hole through the centre of the bolt (cover up everything so no metal bits get in where they arent supposed to be) inserting the correct size ezy out and turning it anticlockwise to screw it out but in saying that you didnt know how to use a torque wrench I would suggest you get assistance from somebody that has done this before as you can also snap the easy out if your not careful and the easy out should be hardend which means that you cant drill this baby out! :redface: :redface:

I will definitely be getting assistance.

I'd say it is in there TIGHT. The washers disintegrated into metal filings due to the force applied. The correct tension is 17nm and I think I applied around 150nm to these bolts.

As for the stripped thread you should go to a pro and get it drilled out and a helicoil fitted which will allow you to replace the bolt with one of the same size and thread! :confused:

Any ideas on how much this is going to cost and whether I'll have to remove the manifold again to have this done?

edit....

Thats gotta anoy ya, very simple mistake but very hard an anoying to rectify. Just out fo curiosity, how much did the torque wrench cost you?

$75 from Bunnings Warehouse. It's a Kinchrome.

Incidently, everyone ravs on about Kinchrome quality and how Sidchrome has really gone downhill in recent years. I was bought this one as I was interested to compare with my Sidchrome ring spanners and sockets (all sets less than two years old). I have to say Sidchrome is much better quality.

Can someone recommend a good place in Brisbane where I can get the bolt removed and a Helicoil fitted?

If someone in Brisbane is able to help me with bolt there is a carton of premium beer in it for you (of your choosing).

Sorry to hear that, I'm thinking of doing my plugs soon so I'll be real carefull now.

This guy is supposed to be good, got his name from a marine mechanic.

Good luck

Thanks mate that's handy.

You'll be right as long as your not stupid like I was. If you haven't used a torque wrench before I suggest you get someone to show you first because they do require care and the instructions I received with mine were not at all useful.

Sorry but i would nt know how much it would cost for a helicoil replacement but as for removing your manifold I would say you would have to because they have to drill and retap it bigger than the size it was and insert a stainless like spring(which is the helicoil) which your bolt will bolt into.Now the holes on your manifold will be clearence(bigger) than your bolts but not that big!!Good luck I hope you can get it sorted without having to pay too much out... :P
P.S I live in adelaide so could not suggest someone.

with spark plugs i wouldnt bother using a torque wrench.....just do up em tight by hand, then give them 1/3-1/2 turn, so they sit tight with a socket. and thats it.

I wouldn't do anymore than 1/4 - 1/3 a turn.

Sorry to hear of your bad luck.

Don't know if this will help you but may help others.

If you snap a bolt off and have enough of the shank exposed screw two nuts onto the shank. Then using a open ended spanner turn the bottom nut. This will take the broken bolt out.

spewin! did this on a 5 litre 308 thermostat housing bolt bak a few years ago. ya gotta learn 2 do it up a 1/4 of a turn b4 it breaks.

snaped bolts are a pain in the ass,

what i would sugest, usually the hole is deeper than the actual thread thats snapped in it, i tend to get lucky and when i snap one, the bit in the hole is pretty easy to turn, just try and get some pliers on to it if you can, if not, the end of the bolt that was snapped off can be pressed against it and used to carefully reverse it out, had to get a bolt out of the hub in the old mans 4runner after he tried to mess with it and snapped it off, works a treat if your careful, but again, it wont work in all cases
