My mate was removing his spark plugs, noticed they where on there way out misfiring at highrpm.

His 2nd spark plug was cracked , so he said he pulled it out and bits of the sparkplug(white bit) fell down the bore he said its pinky finger nail size and about .3cm thick.

what will happen now? he got a vacume and tried sucking it out unsure if its out

is his engine stuffed? or will it melt and eventually come out the exhaust ports?

thx

That white part is ceramic - very tuff and can withstand alot of heat. The reason why they use that material in the first place. It needs to be removed full stop!

This will really do some damage, don't know how you could do it without removing the head, have to think about that one.

Get a hugely powerful vacuum - I have one at home for use with asbestos to drag away all the airborne particles. Suction is incredible.

Do an oil change very soon after and filter. Hope it doesnt get into the big end bearings etc..

I guess you could get an oil sample done to see if any foreign particles in it.

or if hes financial enough...why risk it?, full rebuild...good excuse for it!

I find people like the idea of being forced into doing something major to their car like a rebuild as the situation demands it rather then electively choosing to do it. Tell your gf/wife oh the motor is shagged gotta rebuild, got no choice and you act pissed about it but smile when she turns around!

I had the identical thing happen but luckily only one piece fell in and I could see it sitting on top of the piston using a lead light which was at the top of the bore.

I also tried a vacuum but to no avail.

Went to Autobarn and bought a "claw pick up tool", $10.00 and that got it out just, as i dropped it twice and nearly lost sight of it.

Basically, it is a long flexible coil, thin in diameter, with a small claw on the end. It has a button on the top that when pressed opens the claw, and when released closes it up.

TRY THIS AT YOUR OWN PERIL!!!!

As mentioned, if other pieces have gone out of sight it can do horrendous engine damage. If you are lucky and it blows out the exhaust it will then make a mess of the exhaust wheel.

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
