Hey guys, I was trying to bypass my heater core today and one of the hose clamps was in a bitch of a spot so I ended up taking that part off that you do to change the rear spark plugs, and when I put it all back together and went to start my engine, it made PEEEW noise and stopped. Everytime I try to start it the engine just dies straight away. I've checked all the electrical plugs and everything seems to be ok. I left it by the side of the road and just rode my bike that I had in the back home so if it's not stripped when I get back to it in the morning I'll try and ideas thrown up.

Anyone got any ideas for me to try?

Hey mate
I am not sure about Magnas but ive seen a few cars that have done that ended up being the starter motor try giving it a few taps with a hammer and try to start it.

No ideas to try, but i'll be around with my tool box stripping your car......

Do you mean you removed the plenum chamber? if you did may be you may of left the brake booster hose off gives a massive air leak, causes stalling at idle. or you removed the air flow metre and forgot to plug it back in. sounds like you just need to double check all your steps, take your time and check all connectors have a home even the one's you think you have'nt touched. Just souunds like an oversight. Good luck.

Cheers Dave

Hmm, air sounds would prob eliminate the breather hose being disconnected (shouldn't cause too many probs anyways, besides obvious unfiltered air getting into your intake) - Check your EGR pipe (if applicable) and master brake cylinder air hose, I imagine your TB and manifold were fitted correctly?

Yeah TB and manifold were fitted correctly. It turns over fine, but just dies straight away.

No offence but if you are calling the intake plenum "the bit ya take off for rear plugs" then ill be suprised if you have assembled it all correctly. did you torque up the intake plenum bolts correctly? its always a good idea to get a workshop manual if you are unfamiliar with your car. as stated, retrace your steps and check everything you removed, twice. just wondering, why did you do it on the side of the road??

I live in a highrise so I don't really have anywhere to do work on it at my place, so I just pulled over in a quiet street when I was driving home from a mates place and got bored. I'll definately retrace my steps in the morning, but it sounds like it's not a massive engine failure problem so that's a slight relief.

it will be simple as it was running fine before you started. so yeah just keep at it!! good luck!!

Ok I checked again in daylight and what happened was two of the manifold bolts on the top have broken, and one of the ones on the sides that the nut goes onto has had the thread stripped and came right out in my hand.

I noticed after this that there is a slight gap and the manifold is not sealed on the gasket and I'm guessing that it's sucking in air.

How the hell do I get the broken bolts out, and is there any way to fix the stripped thread on the side one so I can tighten it up as well?

OK
1) This is partly your fault for taking apart half your motor ON THE SIDE OF THE ROAD
2) Your pretty screwed there, gonna need a drill and drill em out....carefully....I'd just get it towed to a mechanics

Sigh, if you don't know how to do things people, DON'T DO IT YOURSELF. Especially when it can seriously affect the driveability of your car.

If you threaded anything and broke bolts (how did you manage that) you're pretty much better off getting it towed to a mechanics and have them sort it out.

yeah, i have to agree with tuffy. you have just done the bolts up tight as possible when they are suppose to be done to a set torque. please get a manual before trying anything else! and im sorry but doing a repair to your car on the side of the road is a stupid thing to do. you had just left your mates house-why didnt you do it there!! you can buy a tool called an easyout that removes the broken bolt. you drill a hole into the end of the broken bolt and then the easyout screws in reverse, so as you tighen it it grips and twists the bit out. also you may be lucky and find if you remove the intake plenum again there might be a bit of the broken bolt sticking out that you can grip and twist it out. you can also remove the stud you stripped off. in future i would recommend using the workshop manual or taking it to a mechanic. oh and buy a torque wrench!!

Tsk, Tsk . . . . someone didn't use a torque wrench, did we? If tight is good, even tighter is better.... OOPS!!! DAMNNNNN!!!!!

I've never used a torque wrench, including when I did the rear sparkies and had the plenum off. If you have half a brain it's not hard to tighten properly with a simple socket.

Spot on mate.

Well I took everything apart again and then used a slightly bigger bolt on that side one that I stripped, and managed to get that side clamped down properly, and also drilled out the broken bolts and replaced them.

She's running again and I took her for a highway run and pushed her hard and she went fine. Looks like I dodged a bullet this time but I'll definately be getting a torque wrench and being a lot more careful in the future.

Life is not the same when you own a torque wrench!

For one, you stop breaking things, and you feel so SUPERIOR to those troglodytes who refuse to use one!! lol lol

I've got one, I just find it useless. I haven't found myself in a situation yet where I've needed it and where a simple socket won't do the job.

i agree

i own one but i dont use it very often... if you personally crack the bolts, common sense tells you how tight to do them up

I would go to the wreckers and get another lower intake manifold and replace it. Actually, get someone else to replace it.
One part of me goes, Stupid thing to do if you dont know what your doing;
Another part goes, we all have to learn the right and wrong of how everything works, now that you've stuffed it up once I'm pretty sure you want make that same mistake again.

Intake manifold bolts only require to be nipped up very lightly.

Yep - bugger all really . . . . checks manual . . . . .15 to 19 Nm, which is like a gnat's fart, not a rhino with a guts ache letting go.

Useful in: replacing head gasket, wheel nuts so wheel bearings and disks don't distort, axle shaft nuts, steel studs in alloy componets, brake and suspension components so things don't hreak or fall off, spark plugs, SUMP PLUGS, etc.

Not to mention the odd engine rebuild.

Just for the fun of it, try doing up a nut to the right tension by feel, then check it with a torque wrench. Odds are you are way off, ie. way over.

I have several torque wrenches and use them all the time

If you do strip a thread, you can use a helicoil to replace the thread but in the first instance is far easier not to strip threads lol

i always use mine on parts like intake and exhaust manifolds as it guarantees its sitting flush. theres no way to get those bolts all the same exact torque without it. try torque down your head by feel after replacing a blown gasket. . I like to know i have all important nuts, bolts and studs at factory specification.
