After a chat with a land rover guy... a leaky head gasket could be the cause.
i have an oil leak from somewhere, not yet looked at.
apparently the head gaskets are a weak spot aroud no. 4 cylinder, where the head bolt goes through an ali part or sumfin.
what happends is when its cold. looses compression on number 4 then when the metal warms up. its ment to seal it..all down to head bolt torque or sumfin,
Anybody else heard anything like this.?
