Heads up on a few items....to get to the bolt on the left side of the oil trap you may need to remove the serpentine belt, alternator, AC compressor, and the bracket that holds both of them to the block....a real pain. IMPORTANT...be sure to take great care to not let ANYTHING (dirt, dust, etc) get in the intake of the block where you see the 6 openings and valves. Gently push shop rags or blue paper shop towels into the openings to protect them. Don't stuff them..just enough to cover the opening.

I had to use 5 or 6 cans of carb cleaner to completely clean the trap. Spray in all the openings and shake it around to loosen the deposits. Use an old cake pan or similar to contain the old cleaner. Then you can filter the used cleaner through a paper towel made into a funnel so you can use it again. I filtered into a coffee can then used a small funnel to fill up the trap, cover the four holes, and shake shake shake...empty it out and do it again and again until no more crusty deposits were in the paper towel filter. Make sure ALL of the hoses of the PCV system are cleaned as well. The small one on mine that goes from the T connector to the intake manifold was completely blocked so had to use pipe cleaners to break it open again.

Ok, I got the intake off. What a pain in the *** for this noob.

Now, I found out I did it the hardway and unbolted the throttle body (i believe thats what it is) from the manifold. I could have just unplugged it. Anywho.

While taking the manifold off, I broke the small plastic tube that is part of the PCV system. My question, how can I replace this? I have shown a pic of my bull in the china shop job.

Also, I read on another thread to gently clean the throttle body while I have it out. Good suggestion?

Kevmcrae-

Oil trap? I am a noob and am only doing the PCV system unless there is something I am missing that I did not read on Vadis. But, thanks for the tips on the intake. I will do what you recommended to keep them clean.

Here are the pics and researching oil trap now.

The vent box is what the hoses attach to by where you broke the one pipe. If you can get the one side out of the rubber part use a small part of the broken hose then use a rubber vacuum line to joint the rest.

I am not following you, sorry.

The part that broke off is at the vent box. You want me to pull that part out then just connect a rubber hose to it?

Dont I need to use a plastic hose for some reason? If I use a rubber hose, will it work the same?

I want to make sure I understand the correct fix.

Also, should I just take out the oil trap and clean it like I was told above? Is that recommended?

Yes it is reccomended to remove it and clean it. But it is a pain to get it out. I always replace them and break the old one out and cut a slot in the bracket so I can get the screw out.

You will need to use a small piece of the plastic hose to go into the rubber elbow. Not sure a rubber hose will stay on the elbow. Or if it does it will be to big to fit tight on the plastic hose on the other side.

Ok, so how much is an oil trap? Cause breaking it out sounds better and then jimmying it to fit.

But, as far as the small plastic tube, its all broken and cracked. Can I get a new one at Volvo?

Learning on the fly here............

They will sell you the entire larger pipe with the smaller one.

BTW, those little silver clamps that go around the hoses, how do you remove those? They look like they cannot be removed unless you cut them. And what do you use to replace them with?

$193 dollars from Volvo for the little tube. Unreal.

So, I guess I get to fab it. Trying to figure out the best way.

If it is just air that flows through it, do i need to seal it at both ends so its air tight?

I believe I can reuse part of the tube and get a rubber tube to fit on to the elbow. I will let you guys now about my never ending blog with my journey here.

Yes that is way out there.

BTW the clamps can be popped apart but not reused.

Ok, I got the PCV cleaned and the throttle body cleaned. I put everything back and had to buy a new small clamp for the hose that connected to the top of the intake manifold.

Now, I am currently putting back the fuel rail. Is there a trick to putting the fuel rail cover back on?

Also, I had a couple injectors pop off and I popped them back in? Any thing I should be worried about? Should I clean them? Let me know, thanks.

BTW, this has been a real pain in the ****! Hardest thing this noobie had done to a car. What up with these engineers making it difficult to get things out? Sorry, had to vent!

Yes I have been saying that for years!! LOL Sorry

Yes just pop the injectors back on. When putting the rail back in I use spray silicon and spray the injectors and intake then slide the rail back on.

You can clean the outside with brake clean or something like that before putting them back in.

Use some Seafoam in the fuel tank as well as through the vacuum line on the intake to clean the injectors really well. Really decarbons the cylinders too.
