Ok so you drop a small washer down the carb and start car...
Discussion
So you accidentally drop washer down carb(without knowing you have) and start the car!!Eek,just done this with a renault 5 turbo im restoring.
Ive looked down the bores with a camera and see little scars and tiny little blobs in one cylinder.It was a really crappy soft thin washer.
The car starts perfectly,idles perfectly but if you rev it theres a little hestation the second you touch the throttle then it revs freely?
When the cars revving highish with choke on theres a little miss every few seconds,with choke off theres no missing,just when you rev it?Seems quite a subtle fault,i would have expected any internal damage to have caused more harm?
Im going to do a compression check and see what that turns up.What kind of symptoms should a slight scratching in one cylinder cause?
Car has new plugs and carbs been sonically cleaned,rebuilt.

Theres no smoking from the exhaust regarding the turbo.I cant believe the sodding washer would have gone down there,thats why i started it!If anyone knows these cars i was removing the plastic 'lobster' from the top of the carb,tilting it towards!!! me,so away fom the bloody carb,while doing this a washer which from years of fitment is sunk into the plastic disappeared!!
I instantly thought to myself no,it couldn't have,as i was taking the lobster away from the carb!!!The washer would had to have jumped up in the air then miraculously found a forward momentum to go back towards the car body!!!!
Just can't believe my luck.Compression test in next few days.I 'll report back with my predictably dire results.

You could bash the turbine blades with a hammer and there'd still be no smoke so that means little.
If it has gone through the engine, it will have caused damage inside the engine, and possibly to the turbo itself.
The damage may not be terrible or catastrophic, but until it's actually taken apart to inspect, you'll never know.
Of course it also depends on the size of the washer, how big those risks are. It isnt a nice situation, and you could just take a gamble and drive on if you think the washer is no longer in the engine.
But it would be nice to know it isnt in there.
It was a small,thin washer.From what i could see with my camera probe thingy it seems to have nearly instantly melted!!a couple of scratches on one cylinder wall and a couple of little melted beads stuck to top of the piston.If it has gone through the engine, it will have caused damage inside the engine, and possibly to the turbo itself.
