ok just done the leak test and the readings i got were as follows

no1: 10 % no2: 6% no3: 6% no4:10%

re tested and got

no1: 8% no2: 4% no3: 5% no4:5%

also had a look with the bore scope and can't see much just a very small film of oil in the bowls of the pistons also had a look up the inlet and there is no oil there no oil in the intercooler either

what you guys think pull the engine out and strip it or any think else i can do to fix it.
to me it still sounds like valve guides but just had these done by ctm in dagenham
