Well........ I read this thread with great interest (thanks everyone) after picking up my Laguna II 1.9dCi at auction last week. It was showing the signs of a blocked
valve as it was pulsing at low throttle and chucking out black smoke when the power had dropped off.
So yesterday, I decided that armed with the advice for removal, cleaning etc. I would give it a go..... Well the valve had previously been split and would not come out for anything
I ended up knocking one of the bolt holes off trying to move it with a punch
I decided then to clean the inlet manifold as best I could with tooth brush and carb cleaner and some added on idle (loads of deposits) and come back to the
valve with some pipe grips.
On re-assemby, the car is idling ok but has no power at all and actually runs slightly better when the injection light comes on
Any thoughts as to what I have done and how I can remedy it? Is removing the manifold for a proper clean wise?
