Thanks for the advice folks,
I have checked the waste gate and this is moving freely, i have just 5 minutes ago finished fitting the EGR removal kit from Allisport. Seems a cracking bit of kit so hope that works. EGR was black inside but seemed free enough to be fair. I have not tried it yet as i am waiting for gasket sealant to dry.
I think it is looking like the diagnostics machine soon if this does not work.
As for oil there is not a drip any where, shockingly strange for a landy.
One thing i would ask is the EGR kit i got left the water jacket in place and just fitted a hose mount in replace of the EGR and a blank plate to the end of the water jacket and said to join the two blue vacuum pipes of the EGR together.
Is there any benefit in removing the water jacket and blanket it off at the manifold or not?
Thanks
