Here's an example fault on the MERCEDES SL (1992 - 2002)
What to look for:
Open the bonnet and look at the front of the engine. Check that there isn’t any oil weeping out of the top and dripping down either of the front corners of the engine.
What it means:
Oil weeping or dripping out of this part of the engine means the head gasket 'goal post' seal needs replacing. If not spotted early enough the head gasket itself will need to be skimmed.
What to do
Have the repair completed. Negotiate a £100 discount for the seal and a further £600 if the head gasket needs to be skimmed.
