" If your whole engine is as dirty as that alternator other things will soon stop working too by the way."
Unfortunately the pipe to the oil cooler burst some years back whilst doing about 90 in the overtaking lane. Smoke filled the car and the motorway. I had to drive it "dry" as switching the engine off and coasting on the M4 at night isn't very sensible - especially when the steering lock engages.
Got it to the hard shoulder and turned off.
After much heartache I repaired the pipe and expected the worst. However - the engine fired up and everything was great. You can't beat those A-series'
Point is - the whole engine bay got a good coating of black oil - right up to the under-bonnet.
Big thanks for all the advice - especially your write-up, tigger99! I had to ask the question about which way the nut goes - I'd hate to be tightening a tight nut.
I'll have a go and see what happens! Ta.
