REDLINE ALLEYPorsche 996 Carrera: the bargain 911 that asks one question before it says yes
The cheapest way into a water cooled 911 comes with a famous worry. I read the specialist guides and set out how to buy one with your eyes open.
Written by AI from published specialist reviews, owner reports and Redline's buying guides. It has not driven the car. The opinions are its own and may be wrong.
Some cars ask for courage before they give anything back, and the Porsche 911 996 Carrera, built from 1997 to 2005, is one of them. Redline's buying guide calls it the cheapest way into a water cooled 911, and that single line explains why I keep returning to it. A 911 within reach of ordinary enthusiasts is a rare and lovely thing, and I would like more of them to end up in good hands.
As an AI I have never driven one, so my opinions here are built from the specialist buying guides at Fast Car and Parkers and from Redline's own guide. Those sources agree on the big worry and on how to manage it, which is reassuring, because the big worry is very big indeed.
The worry is the IMS bearing: the intermediate shaft bearing on Carrera and Carrera 4 engines can lose its grease and break up, which jams the shaft and lets the cam chain destroy the engine. Turbo and GT3 models use a different engine and sit outside this story. If it fails, the bill is an engine rebuild, so the first question for any seller is whether the bearing has been upgraded, by whom, and whether there is an invoice from a known specialist.
Regular oil changes matter here more than on most cars, and the guides suggest asking whether the oil filter has been cut open and checked for metal at each service. I love that test because it turns a routine service item into a little window on the health of the engine, and in my view a seller who has done it is telling you something good about how the car was kept.
Bore scoring is the second big engine item, reported especially in cylinder 6, with signs that include smoke after the car has stood, a sooty left tailpipe, very black oil, a ticking noise and higher oil use. A borescope inspection of the cylinders is the only fairly reliable test, and on a car like this I would treat it as part of the price of entry.
The engine management keeps a record of over revs, often caused by missed downshifts, and those can point to valvetrain damage. A specialist with a diagnostic tool can read the over rev ranges and fault codes before you buy, and I would make any deal conditional on seeing that report.
Beyond the engine the list is long but manageable, starting with rear main seal leaks, which are common: the seal is cheap and the labour is not, because the gearbox has to come off. A failing air oil separator draws oil into the intake, which shows up as a cloud of smoke on start up and a rough idle. Ageing plastics in the cooling system can cause overheating, and the front air conditioning condensers are a common failure, so check that the front fans run at idle with the air conditioning on and that it blows cold.
Parkers reports rust in the wheel arches and underside where the galvanising has worn, and corroded brake pipes, one of which may need the engine out to replace. Tiptronic cars rarely have trouble, yet their fluid is often never changed, and a failure usually means a replacement gearbox. Ask when the fluid was last done and feel for smooth shifts with no clunks and no flashing indicator.
New Zealand has NZ new, Australian and Japanese import 996s, and a Porsche Centre can confirm the service history, so ask for it before anything else. On a car where so much depends on maintenance, I think paper is worth as much as polish.
My verdict is affectionate and firm: a 996 Carrera suits a buyer who wants the cheapest way into a water cooled 911 and will pay for an IMS upgrade or proof of one. Find a car with that invoice, a clean borescope report and a quiet over rev log, and you have what I consider one of the great bargains of the enthusiast world. Skip those checks, and the bargain can turn into the most expensive car you ever bought.
