Was changing plugs and bit of plastic sucker which was from the spark plug loom fell into the hole

 

can’t get it out using vacume or gum so question is, would i just start the car and hope it burns or it can do damage?

 

i am scared it may get stuck between valve and valve seat or i could removr plug, diconnect fuel pump and crank the engine to force it out

Agree with GTSBoy ,Nizmo Man just got lucky I reckon. This is what I found in an engine that came in for repair.

wow and engine had survived?

 

I bought a borescope camera to check inside there and try once again with vacumme and if not then will do compression without plug and if not then leave it for engine to take care of it .

i just want to be on safe side

 

whilst on the topic, what would you put on injector oring to make it slide in and out, would wd40 damage it ?

Use an empty Vacuum cleaner with a small long hose tapped to it. L9ng so u don't drop it in and empty so u can tell when u got it.
Or rotate the engine till the exhaust valve is open and blow it out with a compressor.[emoji39]

I would attempt this method, vacuum doesn't need to be empty. just cut up a pair of the girlfriends/wifes pantyhose and use as a filter in the hose (vacuum hose not small hose)

Vaseline.  Or there is proper o-ring lube available.

How would you remove it though as you can’t get vasaline there

 

you need something that sprays

 

Vaseline was to do with the question about injector o-rings.  Which I would have thought would be quite clear when I mentioned f**king o-ring lube.

As to the piece of plastic......close the engine, start it up, go on with your life.

If you are turbo it will probably create a problem depending on the plastic.
If it's really soft and breaks up easy as maybe ok. But if it's a solid firm plastic don't put it through a turbo.
To many possible problems including residual melting plastic that could screw the exhaust turbine wheels performance and functionality , waste gate & seats , also for na valve seats but that would burn away eventually unless the plastic was tough enough to bend so thin (doubtfull).

If your na turn it over do the the plug out and it may shoot out plug hole.

Bah humbug.  Any plastic will melt &/or burn away within a very short time.  If it manages to make it out the exhaust while still solid and passes through the turbine at idle, precisely NOTHING will happen.  How fast do you think the turbine will be spinning at idle?

Hahaha it's not about how long the plastic lasts. It's about the risk. What if it does catch something.
If it's coil pack rubber it could be to chunky to pass without breaking down.
Initial start will move it before it burns it.
There's an about 89 % chance you can start it fine turbo.
About 99.5% if it's na.

I just think that it can come out another way risk free.

I would if stuck at this point take out the plug disconnect car (No firing up)
And crank it a few times. Then I would expect the piece to have moved out of the cylinder so it won't fry in there when started ......depending how big the piece is.
But I would probably still be vaccumming and missing the vacuum even using it while cranking with plug out.

Hehehe they are my guestemate percentages.

if were talking a piece of the porcine insulator from the spark plug - get it out and don't start the car before you clear it.

if were talking a small piece of soft plastic then meh.

if your worried about your turbo blades, remove the actuator from the exhaust flap and leave the flap wide open. the exhaust gas will take the path of least resistance and there is a verry good chance it will go out the wastegate hole not the turbine blades.

Yeah, probably not.  The gas might be willing to take the left turn to go out the wastegate port, but anything solid will be more than happy to separate from the gas flow and continue going in the direction it was originally travelling - which is towards the turbine.

And I would still be fine with that.  A blown ceramic turbine is a fine excuse to upgrade the turbo, on the <1% chance that it somehow manages to break.

      I think the pic in the first post is another car, and post 7 is OP's car with standard arms and swaybar swaybar swaybar. I can't tell what brand the silver coilovers are, and even if I could I don't know whether the spring rate is OK, if you can find a brand on the shocks and numbers on the springs that might help. Also, if you can measure the ride height from centre of your wheel to the guard that will help with advice too as handling suffers if ride height is too low

      In the first photo you posted, the colour of the control arms are the signature colour for Ikeya. Same for the swaybar, signature colour for Whiteline.  I like Hardrace, they also do hardened rubber bushes if your car is mainly a street car.  I like GKTech as well, but they use a lot of rose joints in their stuff so might not be the best choice for everyone.  The system might have been good back in its day, but it's a prehistoric system now. I suspect that most people have removed the HICAS as they want the car to do what they want to do, not what the car wants to do. From what I also understand, it isn't consistent in it's behaviour on track so it's hard to trust the car/know where its absolute limits are for track use.  Having said that, I think the HICAS eliminator kit was the first thing I installed when I bought my car. I don't personally have any experience with the HICAS system on a race track.

      Thanks for the info. Didn’t know I had aftermarket control arms already? Will talk to my garage. What brand would u recommend if I want to play around with my camber more? I would think my camber is around stock level right now or more negative now due to lowering with coilovers. I will be lower her again 1.5 cm to get some more.    also why does everyone like to remove the hicas system? Is it because most don’t work properly anymore or ppl just don’t like them. Mine is functioning as it should be right now.    thanks for the good info

      It looks like you've got Ikeya control arms and an aftermarket sway bar, maybe whiteline?  Or am I just going crazy? lol Unfortunately it won't, but what it will do is look really pretty. That's about all unfortunately.  How much neg camber do you currently have? Generally lowing the car dials in quite a bit of neg camber as it is. If you do go down this path, your best bet is get adjustable arms, toe arms (or preferably a good HICAS elimination kit) and traction rods. With all 3 being adjustable, you'll be able to dial out any bump steer that is introduced by playing with the camber settings.
