I was comming how from Pep Boys today and all of a sudden i got a nasty motor knock thast progressivly getting worse, I had my dad look at it and hes not even shure. We thought maybe it was a carbon buildup so we sprayed some carbon cleaner stuff in the intake and it didnt help at all. I was jsut wondering if this has happened to anyone else? Has anyone ever had the pins in their cylinder that hold them to the connecting rods wear out. Im at a loss of where to start looking here and woudl like to see if anyone has any opinion they can offer before i rip into the motor
btw the motor only knocks at high RPM and when there is no load on it, and it is not throwing an oil light.
If you took it for Pep Boys for anything it is probably thier fault. Might be a VCT code that you have. The VCT is noisy when it breaks or is not getting oil. Might want to check you oil.
Hey I work at Pep Boys currently and everyone I work with don’t purposely mess up customers cars. It could just be normal noisy injectors like mine has.
