1994 LT1 sucked up plastic bottle cap into the intake!
What potential damage could a piece of plastic swallowed by the motor do? The shampoo bottle cap plugging the donkey dong hole in the intake elbow either fell out or got sucked into the intake a few days back while I was driving. The car backfired through the intake a few times but seemed to run fine other than idling really rough due to the massive vacuum leak at the elbow. I didn't find the bottle cap stuck in the throttle body so I pulled the intake off in case it was stuck in one intake runners. I never found the cap or any trace of it but just in case it really made it way into one of the cylinders, what damage could it do? FWIW, the car's been running fine since i reinstalled the intake.

This is exactly why you dont put a shampoo bottle cap in the elbow like so many people on this board tells others to do. A .25 cent peice that will cause 1000's in damage.
Potential problems are a blown motor. If that bottle cap is seriously in that motor, there is no way IMO that it will get past the exhaust valve. I do however see it getting past the intake valve and into the cylinder....If I were you, Id pull the heads....

you think it could snake through the throttle blades, get sucked down an intake runner, tumble around the short turn and make it through the intake valve? lol epic fail for both of you
You would have to have that thing stuffed on there TOO far, and have a very restrictive air filter to suck that thing in. I couldn't really see it getting by the throttle blades either. It probably fell out.
On another note, it probably wouldn't make it past the intake valve either, and it would likely melt if it got stuck in there. I'd just run it honestly.

If the engine backfired, it would have shot the plug out of the elbow, not ingested it.
Even if it did, it would not make it past an LTX style TB.

Apparently from the Street Racing section everyone and their mothers Honda beats crotch rockets now lol.
This happened once before on another car and the cap couldn't get past the TB blades. I've got a LPE CAI with a pretty clean filter and I didn't feel much suction at that hole, certainly not enough to suck an object that was already hard to stuff in there.
I'm thinking something that big getting crushed by an intake valve would have also nicked the valve seat enough to cause a noticeable loss of power and probably make an awful racket in there if it hadn't already been blown out in little bits through the exhaust valve.

If there was any product in there it'll leave your valves shiny and manageable with lots of body, but I agree, it probably fell out.
Hahaha! I seriously think it fell out too though. Does nobody else think a lousy plastic bottlecap would not survive the compression or the heat inside the combustion chamber? I mean it wouldn't make it past the intake valve unless it got broken up into little chunks, and even then how long would those little chunks survive the pounding and the heat inside the combustion chamber? I would think chunks of plastic that small would get carried away in the exhaust stream once the exhaust valve opened anyway.
I've driven the car about 15 miles since putting the intake back on and it feels just fine. No weird sounds, hiccups or anything to suggest there's something stuck inside one of the cylinders. I think the new intake gaskets must have sealed a vacuum leak somewhere because the throttle response is now a lot snappier and the motor seems to have more power
