I have a 1990 mustang that i recently tuned up. In the owners manual it says to check and replace the PCV & Crankcase filter and I cant seem to find these items. Pictures 1, 2, & 3 give you an idea of the engine compartment and pictures 4 & 5 are the parts Autozone gave me for my car....
Could anyone please tell me where in the pictures the PCV & Crankcase filter are located?????

Thank you....

The Crankcase filter should looks like this.

And to remove that filter you can remove it with either a pair of needle nose pliers or a screw screwed in the the mesh to help you slide the filter out.

Where this filter is located at is at the very backside of the lower intake.


And this is a where you'd place the filter.

Hopefully you also received the following instruction as to what you need to cap ?


If not

 

the car has about 144, 000 miles on it. Is the PCV and Crank filter necessary to replace???? I put new rotor, bosch plat-2 spark plugs, dist. cap, oil change, and dist. wires. I have not set the timing yet and the problem I am having is that when you step on the gas you can feel a little hestitation in the car. It did this before and after the tune-up.
What do you think this could be?????
