+1 Engine troubles on the 3.6 S phase 1(pins from memory). There's an article on Ego Buyer's Guide a few years back and its accurate. A friend bought one 2nd hand and it blew its engine 1000 km latter. Check the work has been done and it will be fine, its a great car and far better GT/ daily than Z4MC. Less exiting too...
If buying the 911,i would not buy the 3.6 but the 3.8 instead. Are they any better in comparison or still have many issues?

3.8 still made from cheese. I would only buy a 997.2 and then you need to add another £10k to the budget otherwise its just not worth the grief.
About the same as the cam and followers on the M then .... 
As with any car, you generally hear the issues - so with many, many times more 997s on the road compared to the Z4M, you will proportionally hear about more problems.
In the case of the Z4 (E85 / E86), you could say that all brake calipers seize, all roofs on the roadster fail, all the cams fail on the M and so on.
I know of only a handful of 997 owners, and never heard of any issues with any of them (including RMS failures etc), but obviously there will be instances where it does happen to someone somewhere.

This is probably a very balanced argument. In theory for every 3 rod bearing failures we hear about we should hear about, what, 30+ RMS failures?

You cannot compare the 997 with the z4m numbers. Compare it with the e46 m3, which has the same engine, and the sold numbers are again roughly in the same ballpark.
RMS is a very very minor problem compared to the 2 main problems: ims bearing and cilinder scoring. Both have the potential to completely write off the block (cilinder scoring= definate write off).
Compared to those problems you could argue the s54 rod bearings and broken vanos bolts, which in both cases also potentially could destroy the engine, but these are easier/cheaper to fix (especially the vanos bolts) and occur less.
Also a porsche replacement engine would be much more costly.
You can get the block resleeved on the 996/997... But it's a it cost and a rebuild is in the area of £10k..
The figures are about one in eight will develop major problems... Hartech reckon that all the engines will see bore score, just depends if it gets that bad the engine is junk..
Then of course you have the shyte gearboxes where they jump out of gear... Budget £3k for a rebuild and clutch..
Save up and get a 997.2 or a 2009> Cayman .. Both good cars...

Sorry but that is mostly rubbish! A massive engine fault and we are not talking about IMS here is not the same as wear and tear roof failing or calliper seizing
997.1 and derivatives engines are a ticking time bomb with a huge cost to fix and Porsche need a shoeing for their burying of head in the sand attitude. Thats without the mentioning of the wear on the gearbox :!:Z4M-2006 said:
I always thought the 997 engine was a nikasil/alusil engine.
10k for resleeving is more than a complete bmw engine I think.
And some blocks crack.....
The amount of photos of cracked blocks of porsches against photos of cracked bmw blocks on google must be about 1000:1 or so :roll:
Yes...... The M95/96 can "D" chunk...
The top of the cylinder gets snapped out in the shape of a "D",its due to the pistons microseizing in the bores,and then feeing itself instantaneously..
Its a heat related issue due to the poor coolant path in the block...

Interesting to see that 911 turbo's are cheaper than gt3's (also in germany if I look on mobile.de), where the turbo was more expensive when new (and has more power).
The gt3 is apparently more popular. Maybe because it's more a drivers car (RWD vs 4WD; both are available with manual box)
