Hi my car is non turbo but this is where eveyone read... Turbo or not no different here

i was getting a huge misfire on the way home and the car almost stalled when i pulled up...

i done the trick where u unplug the coilpacks 1 at a time while car was running to see whats working...

4th was not doing nething... pulled the spark plug out and the bottom of it where is sparks has broken off into my engine (wtf)

it was a NGK INGNITION plug and only maybe 6 months old so (wtf)???

nehow i thought its stuffing up ill degrease and sray clean my engine... let the car dry for a day/night before testing it out with the new spark plug,

it got better for a tiny bit say 1km up the road and then bam... it started again i put my foot down and it sounds like a really freakish rotary noise does not sound healthy at all.

but then at times it goes away for a second...

any ideas on what it might be... my injectors needed to be cleaned i was told by a dude that dyno'd my car a while ago...

but what im most concerned of is that bit of metal from the spark plug that was in the engine when i turned the car on i heard it and it went away?!?!?!

where could it have gone would it be sitting in my sump?

im know im in a f$%kd up position but please just write back helpfull information... on the misfire and where that metal could have gone to

thanks.... P.S. please dont just tell me to goto a mechanic, as it would be obvious... ide like to fix the problem myself

did you check your coil packs? also you said you water sprayed your engine..... Usually this happends when you dont cover your alternator or your coil packs.. To me it sounds like winter went through your engine.............

yes the rubber on the side of the centre platic plate had been warn off and there was water down there so i got a compresser and blew it out the best i could...before changing the plug

so wat could be happening there? will it ever be fixed by driving it?

What gap are you running on your plugs?

im not sure on the gap size i just asked the for plugs from autobarn and i found out the plugs are... " NGK IRIDIUM ix "

if the gap is to big or small could it cause a problem like this?

cause maybe they gave me turbo plugs.

Does the plug look broken or melted?

We need to see a pic of the plug itself, you have a fairly serious problem!

i gave it to autobarn to throw out when i got a new 1 but this is a pick of what happened...

the plug was normal just a bit oily since the black rb25 cover never sat properly

rip the head off the motor, rip the turbo off and pull out your cat - it will be in either one of these.

chances are its sitting ontop of, or stuck between the piston and the bore. if it is you dont want to risk any dodgy attempts at getting it out, using a magnet wont be good enough as there will still be fragments that will cause bore damage.

rip your turbo off and make sure no pieces are in there or have caused one of the fins to chip, and if they have passed through they will most likely be in your cat.

goodluck!

hey man thanks for the info... its not turbo atm but that doesnt matter... when i turned the car on i didnt hear nething but when i drove up the street i heard it hitting the top of my engine... so i turned around and went home but on the way back that noise went away so where do u think it would most likely be as i will look at it tomorrow?

Stuck down the exhaust near the cat or out the back of the car if the cat didnt stop it.

Worse case scenario its still in the cylinder bore.

I'd check the cat first. If you cant find it, pull off the head and have a look. You'll also find the damage its done.

Is it possible they gave you the wrong length plugs and the pistons are hitting them? Or just no.4 like you said?

Sh#t didnt realise the piston could get that close to hit a spark plug?!?!

should i ring them and check that its the right size plug for a non turbo engine

that bit that broke off is probably sitting in ur exhaust pipe sumwhere, it isnt the main concern at the present time.... u need to find out why the engine is missing....

try pulling out all your plugs and make sure they are all the same (none broken, make sure they all have the same colour on the electrode end) mix them around (so put the 4th one in the 1st cyl) and put it all bak together and run it....note if it still misses and what cylinder is still missing

next pull out ur coilpacks and check for external cracks around the body of each coil.... if there is any, best off replacing it now....put them back in and also move them around (so put the 4th one now in cylinder 2) and start it and see how it goes....

what your trying to do is isolate if the missfire moves..... if you have moved your spark plugs and your coils around and the miss is still in the 4th cylinder then u know is either mechanical or your injector. and if you find the miss is still in the 4th cylinder.... pull your injectors out and get them cleaned, put them back in and test again....

after all this probably do a compression test on all cylinders to see if that bit of metal has done any damage...

do all this first before u go ripping ur head apart.... and get bak to us.....

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
