Hello friends, it turns out that I bought a toyota previous year 1991 is a bit old but for what I want it I do not mind the year, well the issue is that I went out to run the vehicle and suddenly it makes a noise like a patter I I can barely reach my destination and when I get it I take out the spark plugs and find that of the number 1 piston that is broken and with the bent electrode my question is if it would be the piston that hit the spark plug and how that could happen is a toyota previous engine 2.4 automatic and petrol year 1991

Hello Friend. and how long have you been since they sold you the toyota
