The Jaguar J60 was not much better, I would like a fiver for every one with a rod through the side, which I have changed. Remember fitting a recon J60 in a Fox once, did the normal inspection test of about 25 miles or so, unit came to collect it, about 4 miles up the road, the engine gave way. I pulled it down for a technical investigation and found one camshaft broken in 4 places!
