RW> The Dexcool in my Z28 was orange...hmmm, could be that it was more water   
   RW> than Dexcool.   
      
   I seem to remember my Monte Carlo's antifreeze was the red Dexcool when I   
   bought it brand new.  Later, it seemed to turn more orange and got the   
   notorious "goop" formations in it.  Looked like a brown sludge.     
      
   RW> I've never had a problem with it and the Z28 has never given me anything   
   RW> to worry about in the cooling department. Early on, I replaced the 195   
   RW> degree thermostat with a 180 and that was the only thing I've done to it   
   RW> in the cooling department up until the coolant flush and change.   
      
   I'm curious to know why some people didn't have problems with Dexcool and many   
   others did.  There are so many factors, it is difficult to say.   
      
   RW> Chevys have been famous for that. The old cork type of gasket would   
   RW> shrink   
   RW> with age and the 4 screws would come loose, allowing oil to seep under   
   RW> the   
   RW> cover gasket. The rubber replacement gaskets were even worse, slipping   
   RW> out   
   RW> from under the cover when they got a dose of oil. I tend to stick with   
      
   I think my 80' Malibu has the cork value cover gasket.  It has a slow leak for   
   years, but not bad enough to make me have to replace it.   
      
   I did have to have one of the value cover gaskets replaced on my Monte Carlo   
   just recently.  I saw some oil leaking recently, took it back to where I had   
   the engine installed, and they replaced the gasket.     
      
   They have been great with the warranty.  Both problems were minor - and both   
   were gasket related.   
      
   RW> My 55 Chevy had a 30-30 Duntov cam in it. Adjusting the valves (.03   
   RW> intake and .03 exhaust} with the engine running and the covers off   
   RW> allowed   
   RW> the oil to pump over the fenders. I found a set of rocker clips (still   
   RW> have them today) that covered the oil hole in the rocker which kept the   
   RW> oil in the engine, until it flooded the head and overflowed onto the   
   RW> exhaust. I learned to do only one bank at a time, shut it down, clean it   
   RW> up and re-install that cover before tackling the other bank of cyl.   
      
   I have never done anything like that, nor would be brave enough to work on the   
   open engine while it was running.   
      
   RW> That it will. Rather than service a PCV, I just replace them   
   RW> periodically.   
      
   Me too.  All that stuff in brand new in my Monte Carlo.
