True but I guess it's what the owner can afford to do. Pay me now or pay me later.Because you dont know where the piece of metal went. What is to say it isnt stuck to a piece of gunky carbon right now and lets loose through the exhaust valve and hits his turbo while its spinning at 20k rpm?
The MINIMUM damage done right now is to the cylinder walls and the piston head, possibly valve damage as well. But it CAN get worse.
this is the first thing i was thinking you should have done. I do it all the time when I do Helicoils and aluminum shavings fall inside the chamber.Lol I like extreme sports.. I saw this video of a dude with similar issue, he ran the engine with the spark plug out for a few mins and little thing popped out, is that safe to do on our engines
If some totally ignorant person came here with the same issue, sees this idiot just driving around with a screwed up motor, it would be a bigger asshole move to not let them know how bad of an idea that is. OP might as well be trolling at this point....but they're an asshole who's right.
I had the same sound. But mine is intermittent. Comes and goes. Not using the car right now, it is sitting in the garage waiting for me to deal with the problem. Upon start, no noise. Boroscope cylinder check, leakdown and compression check ALL passed. No scoring. Could only make the noise happen after the one pull I did after replacing the spark plugs after the electrode broke off. I used the spark plugs past their service interval like a dumbass, and never got around to upgrading the intercooler. I'm thinking the cause was a combination of these two things. Looked in the PCV valve opening and no obvious damage to the valve train from what I could see there. Is the ONLY next step complete disassembly?If some totally ignorant person came here with the same issue, sees this idiot just driving around with a screwed up motor, it would be a bigger asshole move to not let them know how bad of an idea that is.

Did you adjust the gap on the RS7 plugs or were they installed untouched?Hi All. So I also have had the same issue - 17 MK7 Golf R, dropped an electrode in Cylinder 3.
A little history: I ran the NGK RS7 Plugs for 20K miles last year (on stock coils) - no issues what so ever. In January, I put in new NGK RS7 plugs AND the APR coil packs, and earlier this month (at 11k miles on the plugs), cylinder 3 dropped the ground electrode into the cylinder. Upon disassembly, cylinder 3 spark plug was loose (which I cant explain - I torqued them to 30NM / 22lbf myself). Per NGK's website A spark plug that is under-torqued will not be fully seated in the cylinder head and heat dissipation will be slowed. As a result, the firing end of the spark plug can overheat and pre-ignition can occur. Serious engine damage can follow. My guess is, this is what caused the electrode to fail.
First, I replaced the spark plugs with OEM MK7 R plugs. Started the engine, and was getting an intermittent clicking noise (Identical to OP's). The car would idle fine, but would misfire when under any kind of load, and actually misfired on all cylinders (1, 2, 3, 4, Multiple cylinder misfire, and hide cylinder were all codes I got after a 2 block drive). No Bueno.
Next (following OP) - the intake was removed to clean the intake valves. Incredibly - the electrode was still in the intake manifold.
After carbon cleaning was completed, the car has a couple misfires within the first 20 miles - but nothing to throw a code, including several WOT pulls through the gears. Eventually completed another 300 miles today, without any misfires what so ever. FYI for anyone else who experiences this!
