Mondeo - leaking sump seal - should a service/MOT have spotted it?
I have found an oil leak on the family bus - looks like between the sump and the block. I had it serviced and MOTd last week - is it reasonable to be
miffed that this was not spotted or ignored?
I don't have any reason to suspect this is as a result of their work but I am not sure I want to take it back there for them to take the sump
off if they can't spot an oil leak next to the drain plug.
So, how easy is it to DIY - 1999 Zetec 2.0?

Strange for these sumps to leak as they have a thick rubber gasket in a groove in the sump. Check it is not a leak from the filter running down or
just some oil spilt from the filter when they changed it & did not clean up. If you want to change the gasket it is very easy after removing the
exhaust under the sump.

Thanks, will check the filter and see if there is oil around that they missed, but there seems a fair bit of it. As it is a 1999 it doesn't
have the gasket apparently, just gasket sealant.

Someone's telling you porkies.
The blacktop zetec has a 2 piece sump.
The ally upper piece is attached to the crank case in the same manner as previous incarnations - using a metal&rubber gasket which fits into a
groove
The steel lower part is attached to the ally upper piece using sealant but this stuff is *strong*. Ended up having to bang mine back into shape once
I'd finally got it removed.
Are you sure the sump bolt isn't leaking or something like that?

Yep, it's the lower steel part then - Haynes didn't enlighten me on the upper section.

Its a pain to do properly but dead easy. Drain the oil. Undo17bolts with an 8mm socket. Then lever it off and bash the flange flat again. Scrape off
the sealant from both faces. Takes at least an hour. Redo sealant and bolt it back up. None of the bolts go into the oil so its the sealant that has
failed.

I had a MOT where they failed to spot the alternator had met the maker inthe sky. It got home but then wouldnt start as battery was flatter than a
pancake!
The quote from VOSA when I complained about the competance of the test centre was "An MOT is not a proof of vechile roadworthness."
Did call the woman who penned that gem, she hung up on me and although wasnt disaplined on her quote (as its legally true) was then sacked for her
approach to customers!

Sorry Common misconception by vehicle owners & drivers. The MOT is not & does not check the ability of a vehicles starting abilities. If the
vehicle starts and is in the Testers opinion 'FIT TO TEST' then it gets tested. IF an alternator fails during the test but allows the test
to be completed then the tester might comment on it. If it fails during the test but gives no outward symptoms because the battery is man enough to
finish the test then how would the tester know. IT IS NOT a TESTABLE ITEM.
Sorry for the rant jamjah but it is because of short sighted misconceptions like this that I decided to stop doing somthing that I liked.
Oh and don't forget that the MOT test is based around a vehicle that might have been built in 1914ish.

If testers failed cars for oil leaks there would hardly be any on the roads. If teh leak is enough to coat the whole undersize of your floorpan thin
this can have a couple of advantages.
1. Stop the rot! Stops bolts seizing up and floors from rotting.
2. MOT testers tend to shy away from oily under floor areas. Stops them poking about to much with that dreaded screwdriver!!
