With a big thanks to Steve, VeeKay now has a pristine inlet manifold... and the egr bypass pipe, which has been on the car for three years, had no contamination at all
One thing though, which puzzled both Steve and myself:-
The pipe with the corrugations which carries the exhaust gasses, was connected to the bypass stub by a jubilee clip and clamp assembly BUT, the exhaust pipe was only connected to that by a loose fitting collar which is held in place under tension from the corrugated pipe once everything is bolted together.
Can anybody shed any light on this please? Both Steve and I were of the opinion that the corrugated pipe flange should have been gripped more securely.
Would this somewhat less than air-tight joint cause a problem?
Also, Steve noted that it was the first time he had seen the corrugated pipe as a short assembly with a clamp at the other end as well.
What are your experiences of these things please?
