would a blocked cat really stop my my tdci from boosting , the turbo,s going back to the guy who rebuilt it in Birmingham so he can check the vnt and weather there stuck open or closed,one thing i did notice after taking the turbo off was the actuater spring felt far to weak.. and im gona take the cat off and replace it as there only £80.00 the cats done 60000 and when i take it off is there anything i can look for that will say its fooked? one guy told over fueling can fook them up so a snapped compressor shaft will have sent alot of oil thru the cat
