The radiator and bumper etc are already removed so I might as well just get on with it.

 

The thought had crossed my mind.

There is a very slight bevel on the pipe edge already though.

 

Are u just pushing the pipe in /. Did u try to turn the pipe clock wise or so. as u push it in. ?

 

Yup I've tried all sorts of twisting/turning/wiggling/slightly different angles
I've tried different greases, freezing the pipe, less/no grease, etc.

I have used a wire-brush disc in the end of my dremel to clear the housing perfectly.

Every time, I can feel a little bit of the rubber from the front. I see how the pipe feels, and it doesn't want to stay put, I allow it to pop back out and the seal has been squashed out a bit at the flat end.

 

How about using oil instead of grease. its thinner and it might slide in better.

 

Tried that.

 

Thanks though

 

Doesn't the Bimmer pipe have the installation sleeve that goes in first, then the pipe slides into the sleeve and expands it. ?

 

Yeah something like that.

 

Don't give up on the pipe keep trying,, Im sure you'll find the trick to it and get it in. good luck..
