Crank snappers & oil change intervals
Posted: Tue Aug 06, 2019 8:29 pm
Yesterday I was chatting to the workshop owner who looks after Swambo’s Fiat. They specialize mainly in Italian cars, new & old, from Fiats, Alfa’s, Lancia’s, Maserati’s & Ferrari’s, so he has extensive experience in what makes an engine last long. He actually just finished reassembling a 3.0 V12 Ferrari for a 1966 Ferrari 330.
His best advice for making an engine last very long is that oil changes with high quality oil are critical. A number of cars on sale have stipulated oil change intervals that can be best described as optimistic by their manufacturers. It isn’t just the engines pistons that are dependent, but also things like turbos are also dependent on healthy correctly spec oil.
I had a Cooper Works that had supposed intervals of 25kkm but my mechanic reckoned that what came out didn’t look like oil. It looked like grease. My wife’s Fiat has 30kkm intervals but we change oil & filter every 15kkm. But he reckons 10kkm is preferable.
Which brings me to the 2.7 TDi crank snapper in the Disco. I saw one next to the road earlier with the bonnet up & suspect that the inevitable had happened.
It’s well known that both the Peugeot 407 & Jaguar S-Type use a version of that 2.7 engine yet they appear to last a lot longer in the Pug & the Jag.
So I looked up the oil service intervals:
Peugeot is every 10000 km
Jaguar is every 16000 km
Land Rover is every.........25000 km [emoji102]
It’s not a very good starting point for longevity, especially with its inherent flaw. Yet people will still buy them......
