Hello and Welcome to Justanswer, My name is Steve and I am here to try and assist your with your question
these are the parts you need and you need to remove the cam
would also recomend you replace the timing belt
the solenoid I had replaced was on the outside of the engine with just a hint of it going into the engine.
so you are saying it is more then that?
yes it is more than that
also need a sprocket
you need all three parts to solve the problem
Is there anyway to test that this is the problem or is that all that a diagnostic would tell us.
Sorry, there's no way to test it without special equipment
