Dirty Air Filter
#1
![Default](/forum/images/icons/icon1.gif)
Hello Guys, I need some help on this one. I looked under the hood yesterday and did an inspection of my Air Filter. (Just obtained my Jaguar a few weeks ago) and see that its very dirty and needs to be replaced, my concern is that there is "Oil" Residue on 1/4 of it and a little residue sitting in the bottom of the "Air Filter" Casing. Also, the PCV valve appeared to be a little loose and had an ever so slight amount of oily residue in it too. I put that back on securely. (A Mechanic probably was lazy and didn't fasten it on properly after he did his routine) Anyhoo, I believe this is why my Check Engine light and Restricted Performance keeps coming off and on because its messing with the MAF sensor.

Now that's a stupid question: what is a "part load breather" and a "full load breather"? Sorry guys, I am from Germany, already tried various dictionaries, google picture search, etc...could someone kindly explain that to me? or even better upload a pic of it? Big THX, TAG1000
Is this what I have to look for:

And is this the way to "clean" it:

The part load breather is the small plastic tube the connects to the drivers side(u.s.) cam cover. It has a small orifice in it(the nipplethat comes out of the cam cover after you remove the tube) that gets plugged with oil deposits and causes issue like stalling when you get off the throttle exiting a freeway. Once it becomes plugged it starts pumping alot of oil vapor blowby into the and through the full load breather that is the large tube coming off the air intake tube right behind the air filter and mass air flow sensor. Clean out the orifice in the p.l.b. With a 1/8"drill bit in your finger not a drill. Clean the throttle body and by all meens be carefull with the plastic tubes they break easily when older.
Full load=evacuated the crankcase under, you guessed it"full load" hi throttle opening and rpm. The part load= operates under, youire right again part load cruise with hi vacuum. Hope today's leason was helpfull

Thanks for the guide motorcarman. A little bit late, but still - for others it may be in use. As I promised today I fixed the breather problem and took some photos to ease other people with doing this procedure:
1. You have to disconnect the rubber tube from the breather. It is located under the left decorate lid which is covering the engine (the one with the label Jaguar 3.2/4.0)

2. You'll have to remove the plastic nozzle (be careful because you can break it). Now if you have a look inside the breather you will notice that it is very narrow - that's the reason why it gets stuck with oil residues.

3. You have to find some hard wire or some thin metal tool or drill to dig inside and clean the entire whole. It's a good idea to try not to pull all the residues inside the engine but if you do - it won't be a problem.

4. It's a good idea to clean the plastic nozzle. I did this with carburator cleaner spray which is very useful when cleaning oil residues.

5. Next you can clean the same way as in p.4 the other breather and the entire air-flow tunnel from the air-filter up.

I had to replace mine. You need to remove the intake manifold to replace it. Actually, it's not as hard as you might think. The intake manifold seals will need to be replaced, and I also replaced the 2 heater hoses that go under the intake manifold and cleaned the throttle body and all the electrical connections to the throttle body. The hardest part is noteing, photoing or remembering where all the plugs and hoses go and finding the proper tool to disconnect the fuel lines. The fuel lines need a "top hat" type disconnect that slides in and lets the fuel lines come apart. Also, the norma connectors - like on the part load breather, have a trick to getting them apart. You cannot just squeeze and pull. I'll try and post a photo later. But, anyway, it's all in the technique as opposed to brute force. Plastic and small sockets and o-rings, no sealer.

once you get out the old one, you can snake the new one in from under the intake working ir forward from the back next to the throttle body
