Just bought and want to replace PCV valve on a 2004 Mits lancer 2.0 Purchased part No PCV1171 pc 228 from Auto Zone , is this the correct part and need location also any help will help,--------norm

The part stores are correct. The engine you are have includes a baffle device in the air intake and not a pcv valve. The valves for that model you can get are only for a racing modification.

This problem is usually the result of worn rings but since you already did that, then check the passage that the PCV valve is connected to. It might be clogged, causing a restriction. If that isn't it, then drill a hole at least a quarter inch in size in the top of an old valve cover filler cap and install it. Drive the vehicle and see if things improve. If they do, then check to make sure that you have the correct PCV valve installed.

Check the fuel pump fuses and pressure. Also check the coils

take your car to mitsubishi dealer as far as i know, it only takes certain mits oil, chemicals in some oils can ruin the seals in the transmission.

Many fuel problems are cause by a fuel pressure regulator. it is recommended that you change the regulator with the pump. It is also recommended that you use the original Mitsubishi pump(should be about the same price) so that the pump pressure is also correct. The fuel filter is at the intake of the fuel pump so only filtered gas enters the pump.

Oil leak can be attributed to several factors.
1. Gasket failure.
2. Uncontrolled Crank case pressure Failure.

RECOMENDATION:
Tighten both the valve cover and oil pan bolts.
Replace the Positive Crankcase Ventilation Valve and vacuum line.,

INFO: PCV
This is a valve causes a negative vacuum on the engine while its running, As to say if it had a leak in a valve cover it should not be leaking while its running, only when the engine it turned off.

Hope this tip guides you in the correct direction to solve this problem.

pcv vacuum hose ?

It should sit in your valve cover. On the passenger side (if I remember correctly). It should be right on your valve cover with a line that attaches to the top of it.

It is located at the back of the engine near the fire wall. It is gray with a T connector at the top with two hoses coming off of the T and going forward into the intake manifold.
