I don't want to break it!!!!

Looking at the diagram in TB 600-03 it appears that a special tool is needed to disconnect the breather line on the Part Load Breather stub. I tried to insert two small screw drivers to accomplish the same thing with no success. The line rotates freely on the stub but I cannot get the connector to separate. I am afraid of breaking the fitting and then I'm in real trouble.

The fact that the fitting rotates freely I would think that there is some air leakage there. If that stub restricter hole is so critical in size I would think any leakage would cause a problem. Right now car runs fine just a little more oil consumption than I thought should be.

Any ideas as to how to get the connector off without breaking it. And after I clean the hole should I use some sealant,carefully placed, to seal the fitting?

Thanks guys. You're always helpful.

 

Slide out the "C Clip" if present. Then squeeze the 2 "rings" and twist and pull on the connector to disconnect.

 

If the o ring is good, it should seal while being rotated.

 

Jaguar issued a special tool but you can improvise.

Wow...Tripple Wow. Thanks guys for the very quick response. I will make me a tool and have at it. Here's hoping I won't break. I'll report back.

 

I finally got it off. HOWEVER, what I saw inside was surprising. The inside was very very clean. Looked like brand new. AND the restrictor was much bigger than 3/32 inches. In fact my 11/64 bit fit shank in first, just a little snug. Since the hole, or restrictor, is totally clean and has an area 10.5 time larger than what is called out in TB 310-06 I'll just put it back together and call it quits.

I sure would like to know what the function of this restrictor is. Maybe that would explain the variation in size.

Thanks guys.

 

Check your VIN against the range in the TSB for cleaning out the orifice. After a certain production number this service is not required.

 

It functions as a PCV Valve.

 

Really! Well that explains a lot. It looked completely clean. If it went bad I would have to chisel it out and glue in a new one. Why didn't they just make the darn thing screw into a boss in the can cover. Oh well lets hope it never fails. How do you know if it is not working properly?

 

There are no moving parts. If the orifice is not clogged, it is working. If you had issues at idle there could be an air leak where the fitting attaches to it.
