adamplatts Posted February 8, 2020 Share Posted February 8, 2020 Hi. In process of replacing turbo as my 200tdi defender has been blowing blue smoke under load. took the whole unit off and manifold and found the left side port on the head to be pretty oily. A friend of mine says this is piston rings but I am confused as It’s not been blowing smoke all the time and surely worn rings would do this? i am also able to take oil cap off and there’s no heavy breathing or pressure issues should I take the head off and have a closer look or could this be something else? Thanks Adam Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted February 8, 2020 Share Posted February 8, 2020 Failed manifold gasket I would think. Quote Link to comment Share on other sites More sharing options...
adamplatts Posted February 8, 2020 Author Share Posted February 8, 2020 Like the sound of that more than a head off job that’s for sure Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted February 8, 2020 Share Posted February 8, 2020 Port looks no different to the others on the inside, as above, manifold gasket. Quote Link to comment Share on other sites More sharing options...
Sigi_H Posted February 9, 2020 Share Posted February 9, 2020 Are you sure, this is coming from inside the port? Filler cap ie Quote Link to comment Share on other sites More sharing options...

Filler cap ie No not sure at all just going on what a friend said when he saw the photo. He’s a mechanic so normally I would trust his judgement but he saw the oil and said this can mean only one thing ... rings!!! (Then proceeded to rattle off a list of others possibilities) hence I thought a little more investigation was worth while and there’s an awful lot of Land Rover experience on here Quote Link to comment Share on other sites More sharing options...

Thanks yes they all look same to me also. I have ordered a new gasket (Land Rover genuine) and will see I think before I take apart what may not be broken Quote Link to comment Share on other sites More sharing options...
western Posted February 9, 2020 Share Posted February 9, 2020 Check the half circle seal in front of cylinder head below the rocker cover gasket, any oil leaking through will find its way down each side of the engine block 1 Quote Link to comment Share on other sites More sharing options...
