Needs a clean. This is for the later 200 tdi engine Defender or Discovery. For use with the later 'O' ring style oil cooler pipes and not the earlier concave / convex pipes. If you are after the earlier housing then please see my other listings.
If you are unsure, look at the fitting of your oil cooler pipe.
I took a picture of the correct oil cooler pipe that would fit this housing. The pipe is not part of the sale.
