2006 Sport. I'm in the middle of a home service - first time, usually its serviced by my local garage in France. I don't seem to be able to remove the Oil Cap on the top of the engine?? When I twist it, it moves at an angle as though its been cross threaded! I presume it should simple unscrews with a ANTI CLOCK-WISE turn and lift off. Grateful for advice Andrew Kennedy

Hi,put a screwdriver under the cap when you have unscrewed it anti clockwise as it may just be stuck on if it hasn’t been off in a while. Andy.

Mine is very stiff but just get a pair of grips on it turn and lift - you really cant do any damage

PROBLEM SOLVED Andrew Kennedy

NOT THE END OF THE PROBLEM........I had difficulty unscrewing the Oil Filler Cap because the last person had over tightened it!! Now the problem is the pipe the cap fits onto (pipe coming up from the engine) is loose!!!! THAT CANT BE RIGHT. I'm wondering how the pipe is secured? and what can I do about making it secure?!? Andrew Kennedy

I don’t recall a pipe

You got a picture?

Could he mean dipstick tube.

Thanks for coming back Andy!! Not to computer savvy re putting up pictures. Its the short plastic tube section with a thread that cap thread fits into. Some how its become unattached to the top of the engine! It doesn't come complete out, its just loose. After putting the oil cap back on, with a little more pressure, the lot turns. Andrew Kennedy

Thanks for staying with me Andy. I'm rubbish as this.....no not on the web page you suggested. This is the part number for another model but the same item as I am talking about Rover Discovery 3 4 5 Range Rover Oil Filler Cap Genuine LR053016 The problem is when I screw the cap down, the piece of tube its screwed to (which is attached to the top of the engine) moves half a turn. Obviously it shouldn't - it should simple be a quarter spin of the cap to lock it down - end of story. Hope that explains what I am trying to get over. Andrew Kennedy

Oh. The oil cap

As you say should be a brief twist. Don’t know how the tube worksm

Tricky one isn't it. I guess I need to know how it should be secured and what I can do about it. I think I will be lucky if any one comes back with an answer. As the connection is not good, I wonder if I am likely to loose necessary pressure in the oil system. Thanks for all the help Andy!! Kind regards from a very windy and rainy Brittany. PS I don't like it when the car is not working as it should, I've had it since new and its only done 85,000 miles and in generally good nick.  Andrew Kennedy

I don’t think it’s a big issue to worry about.

Looks like it might just turn and lock in unless the picture is just the cap bit only it's listed as pipe and cap, may just need new 'O' ring to tighten up unless a lug of some sort is broken.
