Tips on engine detailing?

I'd quite like to spruce up the engine bay a bit but am loath to use a degreaser or squirt a hose in there - anything that could cause damage
Is there a recommended procedure?

Get rid of the dust and clean as best as you can - then finally spray with Silicon spray.

Unlike WD40 it doesn't attract dust and its last for ages too. Great for doing all the rubber and plastics too - brings them up like new.

I buy mine from Rapid >>HERE<<
 
I would not recommend using any silicone products in such a manner that they can be ingested by the engine even in small amounts. Silicone will cause premature failure of the lambda (oxygen) sensor in the exhaust system.

I inadvertantly killed the sensor on a Peugeot a few years ago by using silicone-based lubricant to ease a rubber component back into the induction system - they take a while to fail after the application of the silicone but it did fail within a few thousand miles. I found out later what the cause was. I'm also informed by a trusted mechanic acquaintance that the dodgier garages create work for themselves by squirting silicone into the inlet side of the engine when they "service" the vehicle.

Nick, that article's really interesting - especially the bit about the need to change the sensor sometime after 30,000 to 50,000 miles. I've had my 993 from about 27,000 miles and it now has 118,000 on the clock and I'm not aware of the sensor ever having been changed. An example of great Porsche engineering or have I just not noticed a reduction in performance?!

Anybody else changed theirs?

Regards
Anton
 
It is interesting. I've never replaced a lambda sensor for reasons of old age but, given their function, maybe it's time I did.
