First, I highly doubt any shop can fix oil cooler leaks for under a thousand, there is reportly 12 hours of labour involved by an experienced mechanic, lots more for a first attempt! It is a difficult job...
Second, replace the turbo intake seal and crankcase breather hose seals first, they are always leaking on the OM642 engine and lots of compliants on the forums about it, no real fix using Mercedes parts, just constant seal replacement. There are other things that can be done if you search around like a catch tank etc.
Third, replace those two seals mentioned above and then thoroughly clean out the intake valley with degreaser etc and wash, flood the entire valley area with cleaners to rid the oil build up. Then decide if you need an oil cooler resealing or not. It is very hard to determine the source sometimes.
