Where did you manage to get a new cat from. and what spec is it ?
I'm currently in negotiations to purchase a club sport spec Morgan Plus 4, time will tell if I get it, hence my discussions with Matt whether he had experienced any MOT problems with those spec models.
One of the considerations for this particular car is the car had a quite light clutch by comparison to my Plus 4 and others manufactured around the same time, that I've tried recently. Why the clutch should vary so much is interesting to say the least. I was down at Melvyn Rutters yesterday and he mentioned a heavy clutch being one of the main reasons (besides mobility) for people moving their Morgan on.
Out of interest I asked whether using an inlet cleaner could damage the cat and the AI answer was
Yes, an intake cleaner can damage a catalytic converter if unburnt cleaner enters it, causing it to overheat, or if it's used incorrectly or excessively, leading to potential internal cracking or substrate failure. Overuse can also cause heavy carbon deposits to break off and block the converter's honeycomb structure, though smaller particles often burn off during normal driving.
