Ken300D,

When my mechanic (ex now) replaced the glow plugs, he never mentioned if they were carboned up or not so I don't know what condition the pre-chambers were in. But since I haven't driven the car hard since '87 when I had no problem blowing out the carbon as I slowly cruised at a constant 110 mph on the German autobahn's, it wouldn't surprise me if they were clogged up. I say "slowly cruised" because I was passed by over 25% of the drivers.

I've decided to run it hard with a few tanks of Redline Diesel Fuel Catalyst and if I still have the engine miss on a cold start and smoke without giving it the additional 20 seconds glow plug warm-up after the light goes out, I'll have my new mechanic determine the condition of the pre-chambers and glow plug relay.

This pursuit is getting interesting.
