I reckon try the arse end approach, let us know if its successful!

You would have to gravity fill it from inside the car with a long hose and a funnel or coke bottle etc.

Go for it!

Well looked into the filling through the arse end approach...too hard need a hose with a maximum 5mm OD to get past the ouput shaft.

So had one last go at the bolt with my new secret weapon blowtorch + vicegrips.

VICTORY!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Heated up the housing again, then absolutely leant on the vicegrips with my feet and it cracked! You should have heard the car creaking on the axle stands.....but finally victory is MINE!

Check the pics

good work

what a relief

that filler plug was getting the better of us all!

Dont over tighten it when you put it back in

Defintely wont overtighten it! Even put a little grease on the thread to assist in the next time it needs to be undone.

Appreiciate everyone advise on this saga - it was the vice grips in the end that performed better than the stillson wrench.

im going to go have a drink

When I get mine out, I will put some of that silver stuff on the threads (anti-seize).

Looks like it was perseverance that sorted it for me in the end...heat, pentrant spray - and it seems vice grips hold on much better than spanners, and even those Stillsons - so tough it out ddgonzal I was thinking of giving up a number of times....

I'll have a drink when yours comes out too!

i was already drinking but now fix that damn rust ben!!!!!! get navmanjnr onto it... stat!

Yeah yeah we'll get to the rust.....I think the windscreen takes priority!
