Kit #: 9205G Installing PCV Tune Up Kit On Defender 90 1997, 8-Cylinder Gasoline, North American Specifications
Hi I'm Doug, your tech support representative for Atlantic British and in this video we are going to cover the replacement of the PCV maintenance on your D90, which will be the 4 liter with the GEMS system. What you will get with this kit - PCV kit number 9205G, and it is recommended to do every 30,000 miles - is 2 rubber hoses, this will be your feed hose and your breather hose, and your oil separator. And we're going to show you how to install this and also how to clean the area up so that it works better, or basically as new. So now we're going to show you how to install the PCV tune-up kit. It consist of nothing more than 2 hoses and your oil separator. Again, anything you do on these it's always best to put a fender cover down to protect your paint. And the fact that these are aluminum you also don't want to set any tools down or put any hard weight on top of these. They can leave an impression. We'll take our light and move the hose out of the way. What we're going to do is - this is your vacuum hose, it feeds the PCV. This does nothing more than plug into a nipple on the bottom of the intake manifold. You can take this out and clean it out or even just take a small drill run it up through pipe cleaner. Anything just to make sure this hasn't been clogged up with any oil vapor or residual varnish. On the other end of the hose, and down inside this socket, we have the oil separator. Now this consists of nothing more than just a little plastic corrugated piece of material that drops down in. Now as original equipment they crimp the top so that this can't be lifted out and up by vacuum. What you will probably do is have to take a pair of pliers or a pair of needle nose and pull that back out round so you can pull this out. Now I've found that in some cases you can fit a drill around the inside of this and literally drill the plastic. You only want to do that with the valve cover off. The plastic can drop down inside - you don't need that. But for the most part you are going to basically uncrimp this. And I'll show you - we can take a pair of needle nose pliers. What you can do is take a pair of needle nose pliers, drop it down inside. 2 hands. Try to spread the legs of the pliers and spin it around. The metal is soft enough where it will slowly work its way out. And it takes a little bit of work. And eventually what you'll do is get that round. In most cases you will probably be breaking this piece out in chunks. They get some varnish build up in them. They get stuck in place. That's basically the main reason you want to clean them. After you get it out, you can take a small bottle brush, brass brush or whatever, dip it in some solvent, penetrating oil works good, run it in and out to break up that varnish. Install your new piece. And when you install it, one end. One end has a stem. The other is flat and flush. The stem will be the part sticking up and you will see that in this one right here. Essentially at this point you have uncrimped the top of that collar. You've broken out, drilled out, whatever, the plastic insert in there, the oil separator. And you've installed your new vacuum hose. You've run a pipe cleaner or a small drill through the pick up so you know that that's clear and you're getting full vacuum. And now we'll move onto the other side where we have one other hose to replace. Right here is your breather hose. Essentially what happens with the PCV, which is positive crankcase ventilation, the restricted vacuum due to the separator on this side is going to create vacuum in the engine down in the crankcase area and up in the valve covers. At the top, you need a breather. Essentially there needs to be air in and air out so that there's a flow of fresh air running through the crankcase to alleviate any corrosive gases that build up and crankcase pressure. This one is nothing more than just an unplug. You have an open port here, an open port here. Small bottle brush, brass brush, it's nice to put a little penetrating oil on it. Brush both of them out so you have a good clean, open surface. Reinsert your hose, put your new hose on. And now you've just tuned up your PCV system. This kit can be bought by calling any of our knowledgeable salesmen. They'll be happy to help you out. You can reach us at 1-800-533-2210.
