2006 Porsche 987 Cayman 3.4 S Bore Score Edition

Or buy a Boxster with the 3.2 engine, and don't worry about bore scoring.
This is probably the safest and easiest way to get the bulk of the Porsche experience with relatively limited scope for real headache. You'll still have the IMS thing to think about, but it'll be more or less the only real worry, and percentage wise, way less likely than bore-scoring on the 3.4, which would also have potential IMS probs.anonymous said:

Hoping I've missed something here that might cheer me up when enlightened..........aren't the 3.4s just as susceptible to the IMS probs as all the others, at least around the years we're talking about? I know in real terms it's not " that " big a deal on any of them in percentage terms, but I thought they were all as like as not to be affected, and that engine capacity had no bearing ( excuse me, no pun intended! ) on it?

Has anyone found a good source of suspension components? Apparently TRW is the OEM supplier but you can't seem to get coffin arms anywhere. Porsche wants £250 per side which is a touch pricey.
You can get knock off stuff from ebay for £60 per arm but obviously it will disintegrate within minutes...
Oh, you can get TRW outer Trackrods from misterauto for £28 each if you need them..

Hi folks. I'm new on here and this is my first post, but I just wanted to say what a great thread this has been and I love the OPs red Cayman and his adventures in it.
I'll declare my personal interest in that I bought myself a silver 2006 Cayman S last July, 50,000 miles on the clock with PASM, Sports Chrono, full leather package etc. Thankfully, I have nothing terminal to report on mine so far.
It came with full service history along with annual engine oil changes which I hope may have saved the engine to date. It hasn't consumed any oil in 2000 miles so far.
I've read all the horror stories about bore scoring (after buying it) and I've read just about everything on the Hartech website too. I must say I did panic a bit. There do appear to be some things you can do though to minimise the chances of bore scoring which I've done to mine.
These engines run HOT apparently, which according to the experts, could be the cause of the pistons binding in the bores and scoring under certain conditions.
As recommended by people out there in the know, I bought and fitted a lower temperature thermostat and replaced the coolant with waterless coolant which has a higher boiling temperature. This appears to be a common mod at quite a few independent Porsche specialists on the gen 1 Cayman S nowadays. I also plan to change the oil and filter at least once a year rather than effectively every two years as recommended by Porsche. I've also used 5w40 oil rather than 0w40 for a bit more viscosity which hopefully might seperate the pistons from the bores a bit more effectively. Some recommend 10w40 or 5w50. All this may or may not work, but I feel better in that I have done all I can to prevent it happening. I really love my Cayman and plan to keep it indefinitely. If the dreaded scoring did rear it's head, then I'd have the nikasil liners and possibly larger engine capacity. I think you can go to 3.7 litres. That would probably take some of the sting out of spending such a huge amount of money on engine repairs.
Cheers

cmoose - I see you had no issues with the meyle coffin arms, do you happen to remember what sort of milage you got out of these? Did you ever replace the control arms too, if so what brand did you go for and what were your experiences? I'm tempted by the EPS ones with polyurethane bushes but I'm not sure if replacements similar to standard would be more suited to a 996 which spends it time on the road, not track.
I'm inclined to think that OEM control and coffin arms might be a better bet than polybushed versions?
Thanks for your advice.
