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.....

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      I don't think the shuffle can damage the turbos. It only happens at low shaft speeds and loads. It's just annoying (to some people - others are tickled by the effect) and it quite possibly reduces spool performance a little bit.

      Oh dear. The panel beating needs to be done before the filler work. Do you have a photo of the dent before you started? Hard enough to not flex and only hit the high spots?  What do you mean it was just temporary?

      I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly.
