Morning,
Not sure if this should be in this forum, or a more general one as its a more generic issue, but anyway...
I am still trying to evaluate the level risk of the 3.4 vs the 2.7 in the Cayman. Specifically the likelihood of a 50k mile car developing bore scoring issues during my intended ownership of that car as a Daily Driver.
Certainly the dealers I have spoken to have played the issue down, whilst the concensus here on t'internet is that it almost a certain to be a problem. I am sure that the reality is somewhere between the two.
From my point of view, I want a car that is going to be reliable, so am investigating ways to mitigate what risk there might be, without doing an engine rebuild.
Reading Hartech's excellent [url:http://www.hartech.org/docs/buyers guide web format Jan 2012 part 5.pdf]buying guide[/url] gives very resounding arguments for the root cause of the problem. It also suggests a couple ways to reduce the risk before failure actually occurs.
It suggests that swapping the thermostat out for a lower temperature one should bring the operating temperatures down sufficiently to reduce the risk of the localised heating issues that lead to the damage.
It also suggests that there may be additives or more modern nano-tech oils that can reduce the risk too.
The document is dated 2012, so I wondered in the intervening time if anyone has tried these methods, and still had an issue, or if there is now an updated wisdom on the subject?
Thanks
Mark
