interesting,the only way to really tell is to instrument the engine and run it, as well as idle in traffic, and most importantly for me, SHUT OFF the engine and let is sit there and cook, and see how the temperature spike.
I see there are threads with guys reading the temps off the engine with and without the cover, but not sure how they do that since the parts you need to read from are covered with the cover --
Funny, I have not seen covers on the 996's or 997's - why is that? Have not been under a 991 yet...
Cheers,
Mike

Just learned last night why there is an under-tray. I backed over a pile of leaves in the street pulling out of my drive with my 993 and in a very short while my wife was calling the fire department to hose down the considerable blaze in the street that resulted from this. Most excitement we have seen in years on my street!

Odd then that Tony Callas, as part of his program at Tech Tactics yesterday went out of his way to talk about how air cooled engines do NOT retain their heat post-shutoff, especially as compared to "water" cooled engines. And how that played into the difficulty meeting cold start emissions requirements.

I run with mine on. It catches any oil drips so when i change my oil it is very easy to see if there is a change. Also, it may have saved me some damage a few times, once this summer for sure. Its pretty scraped up somehow.

What is the best oil for dripping on your engine tray?

I wonder if anyone has invented a bolt on diffuser to put in place of the engine undertray? A diffuser must work better on our cars than many other cars that have them, since the rest of our car is already nicely flattened underneath.

With 300,000 miles on his engine, what we really need to do is find out what material Richard's valve guides are made from.

The key is to make sure you always wipe the tray clean after easch oil change, ensuring you always have fresh oil there. While Porsche never made a rebranded spring roll, any stupid expensive spring roll will work. I like to use thesehttp://www.prnewswire.co.uk/news-releases/amoy-bank-rolls-the-worlds-most-expensive-spring-roll-152962365.html
The price seems to be proportional to typical Porsche parts so O think you can consider these of good quality.

The secret it use Linear rate spring rolls, not progressive spring rolls... Just properly pair them with the correct dipping sauce and you'll never look back.
