Leaky Oil Cooler: What to Do?

Hello,

I'm having the following problem:
After an accident involving my V6 TDI (AKN) engine, I had to remove the oil cooler to replace the power steering pump bracket. Now, I can't seem to get it sealed properly. I've already replaced the gasket between the cooler and the cover, but the gasket between the cooler and the engine block is not sold separately. Does anyone know of another solution besides having to buy a whole new oil cooler just for that small gasket? It's almost a case for Autobild magazine again... a gasket that costs 20 cents, and now I have to replace the entire oil cooler, which costs almost 150 euros.

Best regards,
Eagle.

Perhaps with a good sealant, like the kind used to seal valve covers or oil pans?

See if you can fit some O-rings in there. The old oil coolers had them too. Just make sure they are oil-resistant and don't get pushed out (by being overtightened).

'Sealant? Well, maybe a thermosilikon (the dark red one) could work, but I would definitely make sure the surfaces to be sealed are completely free of grease beforehand using brake cleaner, and I would only tighten the radiator completely after the silicone has fully cured (so that it's compressed and can't move).'
