I should have put judder at low revs not gears. I understand they won’t touch the pump if they think the engines gone, no point. I’d happily sign for the work to say I have no comeback if the engine failed after the water pump is done, that’s the chance I take. They did say it would be cheaper if cash was paid, no VAT involved which I wouldn’t want to do for such a big job. Surely that’s only protecting them.
