Unburned fuel could be due to too much fuel or not enough air. Have you already gone through the air intake pathways to make sure you haven't sucked in a sock or have other significant blockage? Peter Frederick [EMAIL PROTECTED] writes: Gray smoke is unburned fuel. Almost has to be an

That is similar to what happened when the head gasket blew on my 1994 S350. Except that it happened all at once, got gradually. The failure caused oil to dump into the #1 cylinder. The cylinder still fired (until oil pressure built up), and the compression actually went up in that cylinder -

I did not run the engine under that condition long enough to notice any oil consumption. I'm sure it went down some, but with a 10qt reserve, it was not significant. I also suspect that a little bit of oil makes a whole lotta smoke. -Dave Walton On 6/28/07, Marshall Booth [EMAIL PROTECTED]

Hi Ken, The compression is pretty good.. Typically you want the lowest value to be within 10% of the others - which you are. Is it possible the IP timing changed? Does it do this when warm or only when cold? My 91 300D 2.5T did something similar - but it was intermittant. It would smoke

Gray smoke is unburned fuel. Almost has to be an injection problem -- are the opening pressures OK? If so, it's something in the IP, either bad pressure valves or actual plunger/sleeve damage. Check for leaking fuel lines - if they leak out, air leaks in under suction! The fuel preheater
