I REPLACED THE VALVE COVER GASKETS AND CROSSED A COOLANT HOSE WITH A PVC HOSE WICH PULLED COOLANT IN THE CYLINDERS REPAIRED THAT PROBLEM BUT NOW HAVE A NOISE THAT SOUNDS LIKE A LIFTER

Hi,I have a 2004 as we'll,bought it used about 6 months ago,he said he had new valve cover gaskets replaced,our vehicles are know to have leaky gaskets,the mechanic that did the job,didn't put one of the hoses back on right,it put in it in a bind,and cause it to crack and leak,I found one on ebay for about 50 bucks,if you open your hood,to the left are 2 hoses,right at the end is where it cracked and started sucking air,the other end goes around the engine and connects to the pvc valve on the back side,I also replaced the pvc,but the old one was still good,with the leak,it cause the engine to not have any power,also if you look on both sides down on engine,is it leaking oil,if so then the valve cover gaskets are leaking,their's a good you tube video showing you how to do it,plus changing the plugs you have to remove the intake to get to them,whoever came up with this design needs a spanking,lol,let me know if your hose is bad,I will show you where to get a new one,your check engine light may come on,mine did.

Wrangler 6 cylinders engines are a straight 6 engine with only one valve cover. The gasket for the valve cover is sold separately from the entire valve cover so it can be replaced.

Just the hose or the PCV (not pvc) valve? The hose is probably a dealer-only item - go to the Mazda parts department w/the broken piece and they'll get you a new one. The PCV is avl. @ most auto parts stores - and is cheap - <$20.

Drivers side valve cover, facing the firewall. There's a coolant line snapped into it. Remove the rubber elbow, removed the coolant line and untwist the PCV Valve.

if you have a V6 then you might suspect a leaking intake manifold gasket, a common problem. Has your coolant level been dropping lately? If so then the coolant may be entering some of the cylinders and then shorting accross the sparkplugs. Youtube has lots of videos on how to change the intake manifold gaskets.

On the other hand you may have clogged injectors or a leaking fuel pressure regulator

Oil is being sucked into the air filter housing from the valve cover due to a clog in the hose that goes to the passenger side valve cover and connects to your air box. You will need to have that cleaned and cleared out a have the valve cover gaskets replaced. If it persits you can harm the engine because it will **** that oil into engine cylinders and cause you to stall out.

Good luck

IF YOU GETTING OIL AROUND COIL PACK.MORE LIKELY YOUR PVC VALVE CLOGGED. ITS ALLOWING CRANKCASES PRESSURE BUILD UP CAUSING OIL TO BE PUSHED BACK UP IN THE PVC.OR COMPRESSION RINGS WORN TO A EXTENT THAT THE CRANKCASE IS OVER PRESSURIZED. FORCING OIL THROUGH THE PVC VALVE.YOU HAVE A PVC VALVE NEAR THE COIL AREA.THAT COULD BE WHERE OIL IS COMING FROM.

The pvc valve will be located on the valve cover. Or better yet will be inserted into the valve cover. Follow the hoses coming from your air cleaner ( air filter) to the one that goes to your valve cover. Your pvc valve will be at the end of the hose. pvc valve can be tested by pulling it out of the valve cover while still attached to the hose. Start the engine. Place your finger over the pvc valve and pug it with your finger. If you feel vacume then it is working properly. If no vacume is present. Replace pvc valve

I see now;
do a compression check on the cylinders
this will answer the question if a lifter or, valve is damaged the cylinder pressure will be low

The PVC valve is located in the valve cover (top "cover" of the engine, near the oil filler cap) On DOHCs, it is immediatly to the right. On SOHCs, it a few inches to the left.The PVC valve is held to the valve cover with a rubber grommet type seat.

1. Remove the hose that connectes the throttle body unit to the PVC valve.
2. Using your hands, remove the PVC valve from the rubber seat. Wiggle it back and forth, then pull it straight out.
3. You can either clean this with carb cleaner, or simply replace it with a new one (<$5 at most auto stores)
4. Put the PVC valve back into the rubber seat and replace the hose
