Hi folks,
I am new to the world of minis and have recently been to look at one local to me.
It’s quite a nice one bodywork and floor pan etc wise but when you start it there is quite a bit of oil coming from the exhaust.
Is this a common thing or is it a serious problem?
Any help would be greatly received as I can’t wait to get my hands on a mini.

is it oil or just dirty condensation?

 

oil in the exhaust normally represents as blue/grey smoke.

Hi, thanks for your reply.
I suppose it could have been as the car has been sat for about 6 months or so.
The engine also was a bit lumpy when revving the engine from cold and then cut out when off the accelerator.
Any ideas?

Like Nick says, it could be just dirty condensation.

 

When Minis don't see regular use, they will show damp in the exhaust- water is a by product of combustion and unless the exhaust gets hot with plenty of gasses flowing through it, it will build up.  This then mixes with the black carbon in the exhaust and drips out of the back until the whole thing gets hot enough.  This could look like dripping oil I suppose!

 

The only time I've actually seen engine oil coming out of the exhaust was when the turbo failed on my Fiat Bravo JTD, around 20yrs ago.  That caused an almighty mess!

 

The rough running you mention is probably a sign the carburettor isn't adjusted correctly or the car simply needs using.  It's worth noting, cold running is of little importance.  The tune when the engine is up to operating temperature is far more significant and must be correct if you want it to run right.

Probably just needs 'an Italian tune up'.
