New Cayman to me.

[PORSCHE RICH]

Hi,

I am in the process of buying a 987 Cayman 3.4S 2007. I have had a couple of newer Porsche in the last few years but this is my first older Porsche. I have spend weeks looking for the right car. The one I have found has 29k miles and full Porsche history. Every job has been completed at a Porsche dealership. I am just wondering what everyones thoughts are on the IMS bearing. I need to check all the receipts closer but on first inspection I did not see anything. Should I have the job done?

Caymans all had the 'final' bearing design which isn't the issue the pre 2005 987s were. Just drive and enjoy it.

As said, IMS is fine on these.

I don't want to be that guy, but Internet folklore states you should borescope an early 3.4.

Although this one hasn't done many miles, but you don't know how it's been used.

As already stated, you can't change the IMS bearing on this engine without splitting the crankcase.

Borescore is your enemy. There are a few steps you can take to reduce risk though:

1. Forget bi-annual servicing. Oil & Filter change every year at least.
2. Fit a lower temperature thermostat.
3. Warm it up properly before you thrash it
4. Don't under-rev it. No full throttle at 30 mph in 4th (or even 3rd for that matter), ever.

Hi All,

Ok thanks very much for the advise.

Magnum what do you mean by dont under rev it? Can you explain that to me I am not understanding what you mean.Thanks.

Don’t go up the gears too early / at low speeds basically. If you are in 6th at 30mph and want to press the loud pedal, go down the ‘box.

Mine is 2006 bought new, still love it. I would check for corrosion on brake pipes, even if it's been garaged, and do a test drive and check for the hatch bumping on rough bit of roads; both can be corrected, but at a cost

[PORSCHE RICH]

Thanks all for the advise,will do Mike.

I’ve had my ‘06 plate Cayman S for over 3 years - I absolutely love it! I would second changing the oil every year, irrespective of mileage. Sounds like yours has been looked after - but it does need some miles on it so just enjoy, lockdown permitting.

Already been said, keep the revs up! I treat 2k rpm as the minimum at all times, so 3rd gear through 30 limits, not 4th. And especially avoid bootfuls of gas at low revs / high gear. Flooring the gas at 50mph in 5th / 6th is not a good style of driving for these engines, get it into lower gears before you work it.

Anecdotal evidence points to the Tiptronic being most prone to bore score as it likes to change up early, and then doesn’t want to change down when you give it some gas.

Not sure about the 987 - but the 981 with PDK is very apt to let the engine labour (albeit briefly) at as little 1200 rpm, probably the worst feature of PDK.

Hatch bumping is the only thing that niggles me in my Cayman, present since I bought it in 2012 and no Porsche centre has had an answer to the problem - any recommendation for a solution?

Some things never changes - my 944s both did this too!

Apart from quoting the obvious but have you tried adjusting the two rubber stops?

[mikef]

I think that’s what the OPC do - I had them look at it every year while still under warranty. The bumping always comes back...

Have you tried doing it yourself? Doesn't sound like you're sure it's been tried. It's easy enough - 30 second job to move them.

I have another solution - I memorised the location of all the potholes around here and drive around them
