Ok I acrewed up... I was removing my UIM and was removing the IAT sensor... this 1 has a clip on it... Well the clip went flying and here it is inside the chamber. the borscope i have as you can see i can get it there. But it's too long with a magnet or hook attacked to it. This is coming in from the secondary port. Looks like an earlier then planned rebuild just might be in order....I'm so ******* pissed off right now. 20+ years of ownership and never had this happen before.....

That’s not really a screw-up imo...that sounds more like just really bad luck. Someone here will likely have some ideas.
I want to say that I’ve looked at some newer boroscopes that have a long(er) reach and integrated tools for such things. Apparently you already have a scope, but if it’s been a while you might want to see what’s out there on the market. Absolute worse case could you pull the turbos and LIM?

 

Maybe stick some chewed up bubble gum on the end of your borescope and try using that to grab it?

I'd tie some fishing line into the gum though... Murphy seems to be staring at you, lol

 

I have a 5.5mm scope with attachments bought it this week.. but it becomes too long to get it in thru the port. I went in thru the secondary. it's already 1 3/8" long

 

Ya the lim and turbo are off. But can't go backwards on the rotor. That clip is sitting right there...

 

Have you tried sucking it up with a shop vac? I've heard of mechanics rigging vacuum hoses to shop vacs using duct tape for fishing things out of cabin vents.

Maybe try vaseline or glue on the end of the borescope, if you can manage that without covering the camera. Can you very slowly spin the rotor backwards to bring it closer to the port?

If all else fails, maybe try spinning forward and having a very strong magnet ready at the leading spark plug hole to catch as it falls down.

 

I think the shop vac idea is your best bet for this. It may be a PITA to get a good seal between the shop vac hose & the open intake ports, but some duct tape plumbing should fix that.

 

I removed the turbo and lim to hopefully do that. I can only get the scope in from the secondary port. The camera body is too long. But the clip is sitting in such a way that the rotor won't spin backwards. I was hoping to get it to fall out the exhaust port. I can move the rotor forward. I'll have to give the shop vac a try. Mine is pretty stout.

How about Those extension magnets with the flex sections? I have one with about a 3” section of flex. Might need a longer flex section.

 

Shop vac with pantyhose or some super fine mesh over the inlet - that way if you do get it you immediately have it in your hand and don't have to dig through a dirty shop vac to find it. It's a trick that has worked many times.

There should be a way to get it out of there without cracking the motor open. Even if you have to pull the LIM and everything.

Sake Bomb Garage makes a "nut blocker" - it's a plate that sits on the LIM when you have the UIM off the car. Saved my *** many times. I use it every time I pull the UIM.

Ive been checking sake bombs website since I got my car over a year ago to get one of those blocker plates, theyve always said out of stock. I usually take a trimmed down piece of a cardboard box and push the studs through it.

 

Spent a few hours today trying to get it out... Shop vac didn't work tried a few other ideas also... prob just gonna pull the engine and rebuild it early. It is what it is. Few years ago compression tested it and was in the upper 90's. So may as well refresh it along with a few other things. dec my 89 rx-7 got totaled (rear ended me) then i do this....what a year so far.

Carl

 

Have you try twisting a wire around your horoscope, form a hook in front of the camera and go fishing?

 

That stinks! Yeah, it may be a good excuse to go ahead and go through the engine. Good thing is you didn't try and start it with that object in the engine, that would cause a lot of damage.

Dale

 

i barely have enough room for the scope to get in. it came with a hook and magnet attachment but it becomes too long to try and get thru the port.I already have to angle it to get it in.

carl

 

turn the motor backwards a little and fish it out the exhaust port?

 

Ahh, thought a thin wire might be able to sneak in there with the scope.

 

right now it won't let me roll the engine backwards. I'm gonna try moving it forwards and see if it'll move into that chamber on the rotor and then go backwards to see if it'll fall out.

Carl

 

My cheap *** bore scope came with a magnet attachment. Maybe you should just buy one of those cheap bore scopes. It beats a damaged engine.

 

This has saved me a few times on bike engines. Small diameter hose with a neodymium magnet super glued and pushed almost all the way in, leaving a bit sticking out. Test it against some metal outside of the engine to make sure the magnet wont come out. Fish it in, move around, roll the engine a bit at the same time.

 

That is why, as soon as you take off the UIM, you place strong duck tape over the LIM openings!
No matter what work you are doing.

 

I'll usually make a plug from paper towels and plug each runner. They stay in place until the UIM goes back on.

 

Its conjecture, but the IAT has a clip, as in maybe he had a Bosch connector on an early fast reacting IAT sensor. So he may not have been able to remove the UIM without first pulling that clip to disconnect the IAT. In any event the thread is a good reminder and there’s no sense in beating him up with the obvious. I’m usually careful too, but I bet few are without sin here.

 

Exactly what happened.... 8(

 

I got the damn clip out.... moved the rotor forward to see if it would fall into the "chamber" of the rotor so i could get it to come out the exhaust... well that didb't work tried a few times. But i guess i opened the secondary port enough to get the scope inside with the magnet. It worked!
