Oil leak

[Jamie Parker]

Hi, just wondered if anyone has any advice on why i have oil coming out of a bolt that holds the intercooler housing plate on? It only happens at high revs. Im guessing there may be a leak on the turbo which is allowing oil into the intercooler? Any help/ info would be greatly appreciated

Ford sabre 225. Where my finger is, is where the oil is dripping from at normal running temperature and high load

It looks like a salt deposit to me but that’s the danger of photo diagnosis

I don't know that intercooler but many have a very small drain hole at the bottom to allow any condensation to escape. Any oil in there will drain too. The oil could be from the turbo but much more likely to be from a crank case or rocker cover vent that vents into the induction air which will include some oil mist some of which gets deposited on the cooler matrix and is forced out the small drain at high load.

The engine vent from the rocker cover goes down into a box which catches any oil and then vents through a hull fitting so i do not think this is the cause. May have to bite the bullet and get an engineer to have a look
