dreadnought110 Posted September 15, 2009 Share Posted September 15, 2009 Just doing a timing belt on 300tdi 130 wolf and there's oil in the bottom of the timing case any idea which seal it might be? and rough time to change? Quote Link to comment Share on other sites More sharing options...
disco_al Posted September 15, 2009 Share Posted September 15, 2009 if it's in the bottom of the timing case then i would suspect the front crank seal is leaking, as the cam seal is higher up and would show a telltale trace down the cover. worthwhile changing it while it's apart, otherwise you could end up with an early belt failure from oil contamination.

Most likely culprit is the crankshaft oil seal IMHO. You should be changing it when you do the timing belt anyway, takes seconds to do. Check the seal land on the back of the crankshaft pulley, if it's grooved you will need to repair it or replace the pulley. Alternatively, you can fit the seal in a slightly different position so that the seal lip runs on different part of the land of the pulley. HTH. Mark.

Les Henson Posted September 15, 2009 Share Posted September 15, 2009 300TDi lump also has an O-ring behind the sprocket to prevent oil travelling up the nose of the crank. Replace that at the same time. (part number ERR4710) Les. Quote Link to comment Share on other sites More sharing options...
dreadnought110 Posted September 15, 2009 Author Share Posted September 15, 2009 can these all be done without removing the timing belt housing? thanks.. Quote Link to comment Share on other sites More sharing options...
simonb Posted September 15, 2009 Share Posted September 15, 2009 Yep,remove the belt and crank sprocket, seal can then be removed. O ring will be in back of sprocket. No need to remove timing case itself. Quote Link to comment Share on other sites More sharing options...
