Hi everyone, I’ve got what I hope are two quick questions…
I just had the oil changed on my 2007 Grand Cherokee. While doing so, the mechanic said that he discovered that a tube/hose of the PCV system had come loose.
He said that as a result of this, the air filter had been bypassed and that my car had been running on un-filtered air for a while. He recommended a fuel injection service to take care of the junk that had entered my vehicle while the air filter had been supposedly bypassed.
I elected to postpone the recommended service until I did some research. I’ve done that research, and for the life of me, I can’t understand how a dysfunctional PCV system would lead to the air filter being bypassed. So I’ve got two questions:
Can a dysfunctional PCV system lead to the air filter being bypassed?
If so, would a fuel injection service remedy some of the problems that may result from an air filter being bypassed?
