It can yes,I have a Disco II I use it in becuse the exhaust valves get carbon build up and need replaced around 50,000 miles,using seafoam helps by cleaning them and other engine parts up,first time I did use it it was like some 007 smoke screen,after that intresting show going down the highway here I only do it at night.

If you go to a Land Rover Discovery II forum you can see they swear by the stuff,and there is some picts and instuctions on how most people injected it in there engines,might help a little.

sea foam is all right if your using it for fuel. becuz it is alcohol based unlike wynn's products and b&g. and you definatly dont want to put it into your automatic transmission. haha they dont last very long after that.
