Diesel emiissions - failed MOT

This one seems fine. Your MOT tester, however, is something else.

Lower load than the road load and not no load, though.

That was because owners didn't look after their vehicles...

They have looked into it.

Following some of the advice given I ran my Tranny until it was nearly empty then put in a few gallons of BP Ultimate. I then proceeded to drive like a maniac in 1st, 2nd, 3rd etc.. and put my foot down on the motorway for a few miles.

I'm pleased to say it passed! So thanks again.

During the retest I was surprised they didn't rev the engine like mad. I thought they'd done that in the past but apparently that was to try and shake the soot out of the exhaust. Obviously I'd done that part this time.

Why do they have warnings on display saying diesels must have cam belts that are within the recommended mileage, i.e not old and knackered, if they don't need to rev them like mad?

Bastard, the Jensen I play with is only a 440, but it's a convertible :-p

So was mine, I then hammered a bigger crankshaft into it! [1]

Julian.

They do (or should!)

because you wouldn't be happy if we blew your engine up would you now, its called CYA cover your arse or in our case cover our arse's, I refused to test one last week as the cambelt was well over its sell by date, the customer wasn't happy, oh well never mind, next !!!

might be worth changing the engine oil too if you have not done it, I was told this can impact emissions testing, along with blocked air filters. good luck !
