2006 jeep liberty

key factor here, is source

my guess, is the car was never serviced?

and the PCV valve clogged long ago and now you have illegal

engine bypass gases venting at hoses cracked or lots of places

and the PCV gases do stink, that will wift in the the cab.

that is my wild guess. but do get a mech to find it.

we can smell anything here, nor try to find source.



and do replace the PCV if clogged. or at 60,000 miles.



high oil usage , do tell, quarts per 3000 miles.

and high speed will suck more oil as will running thin oil.

Try unhooking your battery. It should reset the light. If that doesn't work it could be the relay again. I have had that happen to me with my 2001 Expedition. Was told it was caused by me giving someone a jump and it caused the service engine soon come on.

change the pcv valve this maybe the cause of it burning oil.causing too much pressure in the crankcase system

Hello,

I searched pep boys, advancedauto and autozone and found no PCV valve listed for your 4.7.

I can say however that the last model Jeep (WJ) with the 4.7 had a PCV valve (cuz I owned one), and yes it was on the side of the engine.

You may also like to know that 4.0 (ZJ) Jeeps dont have PCV valves as well (cuz I owned 2) however the V8 (ZJ) V8s do have one (cuz I owned the rare 5.9).

Hope this helps.

I suggest check your Jeep-KJ-Liberty-Service-Manual (page 2068 BODY Section)

Hope this helo to solve it (remember comment and rated this post).

Hope this helps

If you are picking the product up at a major auto parts store, they will be able to tell you. you will need to know, Make, model, engine size, Air Contd, 2wheel or 4 wheel drive. Once they have this they can tell you what the recommended products are and the capacity of each.

Hope this is of some help.

If this is the 3.7 then it will be on the side of the oil fill neck which looks like a funnel.

HOW OLD IS YOUR PUNTO & IS ENG LIGHT ON?

The Jeep comes with Platinum plugs from the factory.
And also a little secret-They are guarenteed from the manufacture for 1000,000 miles
Your Jeep should have Champion plugs in it.
