I have been reading up on wetstacking/slobbering on diesel engines and the various causes.I am looking at a Case 440 skid to buy. NOT the same Case 440 from an earlier post with corrosion. This is a different one!This machine has under 1,000 hours. I noticed it had shiny "slobber" at the exhaust that is dry to the touch but was obviously wet at one point. Owner said machine wasn't worked all that much and was probably due to idling. Previously, when engine was cold it would smoke a lot until it warmed up. Owner took machine to Case dealer and it was found that the coolant temperature switch was bad which affected the cold start advance. Once the temp switch was replaced, no more smoke. I was shown the Case Dealer receipt stating this. Any future costly repairs I should be worried about regarding the prior slobber and smoke or does the machine just need a good hard workout to burn all the crud out of the exhaust? Is there a way to tell if carbon has built up on the cylinders, damage to turbo, etc?  I am a novice at this so my skills are limited to just checking basic things without the advantage of having special tools or taking things apart. Thank you.</blockquote>
