I had a visit from fellow GT Porsche contributor Peter Morgan last week and, as ever, we had a good chat about the world of Porsche. Peter mentioned that he’d recently written an article on the M96 and M97 engines used in the Porsche 996, 997, Boxster and Cayman up until around 2008. Peter and I agreed that a lot of nonsense had been written about these engines and their supposed issues – mainly with bore scoring and IMS (intermediate shaft) failure – have been blown out of all proportion. I’ve addressed this in a previous blog post and, naturally, I was keen […]
Read up on Porsche 996, 997 and Boxster engines and you’ll soon be scared silly by stories of IMS (intermediate shaft) failure. Actually, it’s the bearing at the end of the shaft that can fail and, thankfully, it’s a rare occurrence. If the bearing does break up, though, bits of metal will get pumped around with the oil and will soon destroy the engine. As I said, it rarely happens but if it does, you don’t get any warning until it’s too later. And having that worry at the back of your mind can spoil your Porsche driving experience. Now, […]
A lot has been said about IMS failure on Porsche 996 and 997 engines and this video gives a useful explanation. I must stress, though, that failure is rare, compared to the number of cars on the road. It certainly wouldn’t put me off buying a 996 or 997 – and it shouldn’t you, either.
