Thread: TD6 Oil leak – filter housing / cooler

Hi Guys

I’ve sprung a leak, It appears to be coming from the filter housing / cooler assembly and has become a significant leak in a very short time.

Looking through RAVE (ENGINE – TD6 Integrated Oil Cooler and Filter Assembly) there is 2 gaskets – between engine & fiter housing – between filter housing & cooler. I assume it is coming from one of these, this weekend I aim to see if we can see which.

Question – can I buy these gaskets, or can I cut them from a gasket blank? Looks like it’s not the biggest job to do.

I have a new crank case breather coming. Given the volume and speed this has started, I am assuming it is clogged.

Just a follow up.
I waited for a box of spares to arrive from the UK before looking at the leak.

This ended up being far simpler than first appeared. Removed the covers to get a decent look. After a good wash, then a drive of about 5km, it seamed to be coming from the oil filter cap, neighbour stuck his head in to give an opinion, mrs inspected the issue - we all agree not to pull the cooler off at this stage.

Did an oil & filter change with new O ring, thorough engine bay wash and after 200km+ there’s no sign of a leak.

The old O ring looks perfect, appeared to be sitting OK. I checked with torque wrench when leak first started to make sure it wasn’t loose. I can’t get over how much oil was pouring out of a seemingly good O ring.

I now have 2 intricate looking gaskets in my box of spares. They were 10 pound each if anyone needs one urgently.
