skoda rapid 1.2 misfiring problem leads to engine overhaul part1

[@iainp93]

Great vid, that engine doesn't look very old. What do you think caused the problem? Manufacturing defect?

[@mechanicigor]

Yes on second piston the gap between piston ring was bad so when the piston ring was pressed to be installed it stayed like that and the compression was on second piston ring and that's why it snapped in tiny pieces

Excellent work you did😂... Friend, I have a situation on my vw polo 9n3 1.2 12v, the rotation takes time to download😔, the pole has the rotation between 2000/3000 rotations but I no longer have my foot on the pedal... .it only goes down after 4 seconds... but it only happens when I'm driving... could it be the rotation sensor??😂

[@mechanicigor]

did you check for fault codes

[@Carlosmartinhox]

@@mechanicigor There are no errors, it has already been checked... But I noticed that the vehicle's rotation is very unstable, for example: the rotation is sometimes higher, and it takes time to lower the rotations... it could be the rotation sensor at the end of life...😊

@@Carlosmartinhox I don't think so if crankshaft sensor is bad you get fault code and no starting

[@grayslayers]

Why not just do a compression test and leak down test.
That would have diagnosed that pistons.

Got the same issue mine starts and drives comes up cylinder 3 put 3 new plugs in still the same engine shakes and limpmode still

Change the coil in different position like first one on cilindar 3 and third one on cilindar 1 if it's the same check the compression
