My DDiS (diesel) Jimny is going away ... use me while you can

So it's quite normal to "ram" the M13A engine way over 5000 RPM!?

Coming over from diesels, I am quite shocked and a bit terrified to do it, as I've rarely touched 4000 RPM on any diesel. Over that they all just scream in agony.

I suppose that I should not rev the M13A engine over let's say 2500-3000 RPM just after starting (while it is still cold) until it warms up after 5-10 minutes? Or can I?


Also, when descending downhill on engine braking with M13A engine, up to how high RPMs can I let it brake and scream until I should begin assisting with the foot brake, to prevent engine blowout?

With any engine showing them some mechanical sympathy is good, so let them warm up before revving them hard.

You will have to get used to revving the petrol engine high. It's where they are happy. Peak power is around 6000 rpm, peak torque is around 4000 rpm.

Use a good quality oil and change it regularly and the engine will last. If not then sludge will form at the rear of the head ( No.4 cylinder) and they can seize.

When I first took on Ermintrude as a daily drive she had spent 18 months being driven at not much more than 3500 rpm and was a slug, wouldn't rev cleanly above 4000 and wasn't capable of more than about 175 miles on a tank of fuel. Within 3 months she revs clean and regularly gets twice as far on a tank of fuel and has done for the last 60000 miles. Don't drive it like a tractor, drive it like a sports car.

The above was also true in my purchase. Hesitant to rev beyond 3500 ...... after a full service and a change of scenery..... Norfolk to Dorset.... it revs like the proverbial....it just needs care & attention, like all quality pieces of engineering, a right little gem of an engine.....
