Thread: Leaky's leak

You sure? TD5s usually let you know if you have HG problems...
Your pic doesn't show the entire thing. That housing contains the oil cooler. The cooler is surrounded by, well, coolant. They usually cause an oil in the coolant issue, but maybe in your case the actual housing may be leaking. There are gaskets, and the housing could corrode if the car hasn't had proper coolant in it at some point. Might be worth a look before tackling a HG.

If it is this, change the cooler while it's out.

PS: I think the housings changed a little over the journey, but the principle is the same.

Not the greatest vid, but you'll get the idea I think, in the first 30 secs.

You'll need to pull the exhaust manifold, it is the screw in core plug that is leaking, not the head gasket.

It's worth getting the manifold machined back to flat while it's off, also replace the studs and gasket.

Cheers

Yep, that too. I had forgotten that one. As for the manifold, I upgraded the studs at 4 and 5 to M10 I think it was. It had snapped three of them anyway, so why not?
