What If Debris Falls In Injector Holw When Cleaning

Topic: tiny slice of metal dropped in injector hole - pull head or not on low budget  (Read 6223 times)

August 30, 2022, 01:29:12 pm

I was trying to pull an injector rut shield out with a pick and broke a .5mm ten ane-2mm long piece off the terminate..information technology fell into the prechamber and presumably into the cylinder.

I was unable to fish it out with a magnet, and tried a shop vac hooked up to a tiny straw ...I don't retrieve I got information technology only information technology'south possible the piece of metal was so small it got sucked correct through the mesh I was using inline every bit  a screen to run into if I was able to suck it up_  not 100% sure but information technology'due south probably still in there.

Anyways I am on a very low budget and don't know the history of the engine or how much life left (was pulling injector to check pinch in the first place)...
Would you in this situation:  pull the head?
Take a take chances and effort to run information technology with the small-scale metal slice nevertheless in there

On a side note, given that I don't know annihilation nigh this engine condition and would rather not spend $$ on information technology until I know, any comments on WHETHER OR Not I Tin Become BY WITH ATTEMPTING TO REUSE THE HEAD GASKET AND Caput BOLTS?  This is an 87 hydraulic 1.6td.

Advice much appreciated. thank you

I definitely wouldn't run it until that metallic is for sure out of the motor. If the motor isn't worn out already, it wouldn't have that piece of metal long to bend a valve or score the cylinder walls beyond recognition, and so you've definitely got no other selection only a rebuild. Pulling the caput will likewise give you a better look at the condition of the motor. I've read several instances of people reusing gaskets and bolts successfully, then if $45 is not available for the new stuff, and y'all're reasonably sure that the bolts are original and you don't damage the gasket taking information technology off then I would give that a try. Anything is better than leaving that metallic in the cylinder.

If I was in this situation I would become dorsum to the Store Vac idea.  I would first pull the glowplug and so put a straw in the injector hole and bring the Piston upwards to the tiptop of the stroke.  That will close the valves.  Then I would suck out from both the glow plug and the injector pigsty and meet if anything comes out.  Accept y'all run a magnet over the stuff that might be in the abdomen of the shop vac to see if the piece is in there already.  If not attempt it and make clean the belly out before you lot suck on this again.

You lot have to be able to run across that piece of metallic earlier you do annihilation else to this engine.  The chances of messing upwardly a valve or pushing it into the top of the piston are pretty good right now.

The other thing y'all might try is the scope idea and meet if you tin get that through the GP  pigsty and decide it is gone or not.

That's all the ideas I have right now.

Then I tried running a magnet through the bin in the shopvac - no luck..  cheers for the suggestion.

I also do take a pickup magnet like the one pictured - withal it barely fits down into the cylinder from the prechamber.  I take tried rotating the engine up and down and it doesn't pick up anything...

I think possibly with a much smaller "tip" and a more than snake similar magnet, I could have more luck.

To be clear I have pulled the injector, injector washer, and the glow plug and the all-time access is from the injector from above, the glow plug hole doesn't provide much admission...

Thinking about buying a cheap bore scope from ebay, I wouldn't mind having one...

mtrans, if I am reading your suggestion correctly, you had a cleaved off glow plug tip, and you lot turned over the engine briefly and it shot the slice out of the hole?  Was the broken glow plug tip stuck in the glow plug hole or had it fallen downwards into the engine farther.

Whatsoever more thoughts on: if I have to pull the head, could I go away with reusing the old headgasket and bolts?

Thank you for all the input and suggestions!

I have a magnet snake I got at the hardware store that is only the thickness of a coathanger, and flexible. I got it because my auto somehow swallowed a socket within the body chapeau between 2 unlike pieces of sheet metal and it would gyre around and make noise. Was a 30 second job to extract it with that. So you could try that.

If yous're going to spend money on a borescope, I would say simply get the gasket and bolts (or better notwithstanding, studs) and pull the head. It's not that expensive. You would also come across the condition of the engine, you should be able to observe the amount of wear on the cylinder bores, any melting of pistons from injector problems, audit the caput for cracks or have it tested. And since genuine one.six turbo hydraulic blocks are pretty rare, its worth rebuilding so you will need a caput gasket anyway, I wouldn't trust a store to use the correct 1 since there are different thicknesses and I've heard of places just running the thickest one so they don't accept to worry about it but that drops your compression. If you decided not to bother with  I suppose you could always return the gasket if you lot don't try to install it.

I don't call back you would accept a lot of luck with caput gaskets that don't seem to last that long fifty-fifty when everything is working. Your engine has the former use TTY bolts.

I would try sticking the magnet equally far into the engine equally possible, and and so blow air into the intake (with the correct valve open). Information technology might crusade the piece of metallic to fly effectually and become caught on the magnet. The force of the air coming in may push the piston downwards rapidly so be prepared for that so that valves don't go damaged or wrenches thrown in your face. 140psi out of an air compressor makes a fair scrap of forcefulness within an engine if the piston is non at BDC.

Like already mentioned, do non run it till the droppings has been found. Brand your ain magnet that will fit in the hole. Epoxy a small-scale chunk of magnet to a wire. Make sure the magnet is well fastened and cannot come off! For future reference, exercise not use a pick to get a stuck estrus shield out. Utilize a 1/4" diameter punch. A few taps on the perimeter of the heat shield and information technology'due south dislodged from the carbon and easily fished out with a magnet.

The last time I had a stuck heatshield and none of the "proper" methods worked,  out of frustration I concluded upwardly jamming a small flat caput screw driver in the centre and pulled it out

Gee I take my heat shields out with a pair of needle nosed pliers.  The are the kind that you have to hold closed or the spring keeps them open up.  I squeeze them tight, insert in the hole and release them, they open up and I pull them back out with the shield fastened.  Never had this carbonized in place issue.  But then my engine only has 138K on it and I accept had information technology apart enough once I got it at 117K.

  feel sorry for you lot guys that accept to beat on them to become them to give up to a improve place.

Yeah,on my FIAT 2500 NA engine simply for record,broken glow plug tip is ,I retrieve inside motor,because I can`t find.
That hapen with it?

Mtrans,  My father taught me about of what I know almost small engines and such.  His nigh taught lesson?

Never ever buy a FIAT.

The one lesson I learned early and nevertheless remember.
