Hi, having been a long time occasional reader of the forum I finally got my own mini a few weeks ago. It's a 1985 Mayfair, and there is not a lot of bodywork to do which for me was a priority. It runs and drives and I am delighted with it. A few questions though, if anyone has any ideas...

Have added some pictures below - the engine has an oil leak - down front of engine and sump is covered too. Oil seems to be coming from or collecting around dipstick - is this common? Where else could it be coming from? A lot of cleaning required under the bonnet...

There are some unusual plates riveted under the bonnet - I'm certain they are not from this car, any ideas? The VIN plate that should be there is also present, not sure why these other ones have been added.

I'm planning on a full interior replacement as what is there is mismatched and tatty - also want to upgrade the dash. Wheels are going silver as I don't like the black. Full service too this weekend. Looking forward to getting to know it really. 

Thanks, Ed.

Mini engines covered in oil is very common.


It could be leaking from the oil pressure switch, the banjo union or the pipe between the union and the oil filter housing.


Try cleaning the area with Jizer and then run engine to spot leak.

The oil leak might be a partially blocked engine breather causing the oil to blow out through the dipstick hole. Seal the dipstick and try fitting a small bracket and a spring to hold the dipstick in place. Clean out the engine oil breather and, if necessary, add a new one at the clutch housing. They are available from Mini Spares.
