Oil leak 2.4 JTD 20v
I was just celebrating the first month without a personal contribution towards my local Alfa specialists' financial safety, when my Alfa (2003 2.4 JTD 20v SW) decided to hit me with an oil leak. It's not so much yet, but I'm going to have it checked ASAP. Any good places where to start looking?
If it makes any difference, I was having a loud turbo whistle since getting the car (around 1800-2000 RPM), but the local indie said "it's just a bit louder than normal, sir", while the dealer came back with the usual "you must replace the turbo" line (with a 50% markup on the price as well).
Is there any chance the two are connected, i.e. is any of the turbo-related pipes likely to crack and generate the whistle AND the oil leak at the same time?
