Today I decided to change the oil and filter on my 1.8 escort diesel, until i tried to undo the sump plug ! try as i might i could not undo it. The trouble was that the plug itself had its corners rounded, making the spanner slip. Help !!!
Is there another way I could undo the plug ? Or is this now best left to a garage to help !!
Dead easy to round off Ford sump plugs unless you use a 13mm single hex. socket. A single hex 1/2" socket is a bit smaller, you might be able to hammer one on. If it's completely rounded try a pair of stillsons on the shoulder part of the plug, it usually works. (you'll see what I mean if you look at the new plug). Hammer and chisel is the next step, again on the shoulder part.
I've managed to do the same on my Saab. I have decided to bite the bullet & rather than make things worse, let them sort it out - at the end of the day, if you chew it up badly & you can't sort it, it will then be more difficult (therefore more expensive) when a garage has to eventually sort it!. I suspect that it is the sort of job that will be very easy if you are standing upright with the car above you on a hydraulic hoist. I have already bought the plug & asked the local garage to do it (much cheaper than the £70 per hour +VAT charged by the local Saab dealer), but for various reasons they never got round to it. My mistake was not being able to get right under it in the first place, if I could have done I could have got the socket square on straight away.
When I last bought an oil filter, I was recommended (by VAG garage) to buy another sump plug as a matter of course! I compromised and just bought the copper washer, but it makes you wonder what the garage normally does to them (probably with an air tool set to do up wheel nuts)...
The Ford Duratorque engine (as fitted to a Transit) has a sump plug with about 2 pence worth 'O' ring as a seal. Easy enough to remove and replace the ring, but it isn't available as a 'part'. Comes complete with sump plug at about £3
I find most sump plugs and oil filters for that matter overtightened by some gorilla with the attitude that "as its oil, its crucial, and I'll give it some extra to be sure". It does more harm than good. Torque it up, Brian is right, it will not come undone.
