Kaleb helped me out on another list (before I found this one again) on a massive oil leak on my just purchased 85 300SD. He correctly identified the hole in the oil cooler. Sourced out an upper oil cooler line at about half the dealer's asking price. It arrived today, but have just spent the last three hours in frustration trying to install it.

I cut out the old one, so it came out easily. However I can't find the right combination to weave it through from the oil filter to the oil cooler. Been removing parts to make it easier to get at, but nothing is working.

Anyone been there, done that with this?

Thanks,

Martin

List wisdom rules! Kaleb nailed it. The PO or their mechanic had routed the upper oil cooler line too close to the belt for the air conditioner compressor. Over time, the belt had worn a groove and eventally a hole into the cooler line.

Now I just need to find an online parts supplier who will ship to Canada.

Thanks to all who responded,

Martin

Sounds like you have a pin hole in one of the oil cooler lines.

Hi,

Quite sure it's engine oil as it has the same consistency and colour as what
I see on the dipstick. I was down two litres on the dipstick.

The other symptom is the power steering began to act up at the same time. There is so much oil at the front it's coming off the v-belts and sprayilng up on each of the fenders when the hood is open. Wondering if the oil is causing the belt to slip. Checked the power steering fluid and it was down
about two inches from the top.

Thanks for the response,

Martin
