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.

      Possible swap on R34 RB20DE NEO?

      By GTSBoy · Posted

      If the RB29 box in the car is a push clutch, then yes, you will need to deal with the pull clutch on the turbo box. You either buy a pull clutch and don't use the old one, or you do the things needed to convert the turbo box's clutch arrangement over to push. Which is a bit of a f**karound. "Making" a custom tailshaft is the easy part. But you will need to source the front clip yoke - the bit that goes into the output of the gearbox. These are not as easy to find. They are out there, but they don't grow on trees the way that they used to.

      Turn signal wiring question

      By GTSBoy · Posted

      Indicator bulbs are way too bright to use as a "corner marker" (we call them parking lights too). Sure. Go ahead and do it. But realise that you wil need to come up with all your own wiring to do it, as no-one will have a standard howto worked out for Skylines. It's just a matter of abandoning everything that Nissan have done and starting from scratch. You'd probably be better off retrofitting tailght/brakelight globe bases into the front indicator housings and using the taillight circuit for your corner marker and the brake light as the indicator. You'd need to work out how to kill the marker circuit while the indicator is flashing, otherwise it won't flash on-off, just bright-less bright.

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
