Hi guys, my '91 300E 4Matic has 191K. I just had the head gasket and radiator replaced. Car runs great, but now I have a couple leaks to deal with.

It appears the left oil cooler line has developed a leak that spills a leak about the size of a donut every time the car is parked. Question being, do these things just occasionally start leaking? Is it normal? I have a replacement line on the way.

Also, a good size oil leak is coming from the lower block. Any ideas on how much shop time that job takes? Cost?

Thanks in advance!!
