Smoke on start up
Hi,
New to the forum with a 1999 F350 Crew Cab 6 Speed manual. First diesel I've owned, have run many in the past, but still learning rapidly.
I'm getting a small puff of blue smoke out the exhaust on the first start of the day for the past couple days. I'm in eastern MA on the coast...temps have been about 40 each morning. Is this merely unburnt fuel or a sign of something worse? The smoke lasts for about 30 seconds then the exhaust goes back to normal. In my other trucks with gas motors this was a sign of the head gasket being shot.
Any insight is appreciated...Thanks.

Welcome to FTE.
Blue or blue/white smoke is caused by insufficient fuel or oil consumption. This is normal when engine is cold or idling for extended periods. We have glow plugs to aid in starting and help minimize this. Remember we don't have spark plugs to ignite the fuel, so cold temperatures act different on a diesel.

Thanks...figured it's most likely nothing. Always wait for the glowplugs before starting. Should have guessed it was nothing as we have the same issues on the boats I work on this time of year. Most diesels on boats lack glow plugs...They take a while to crank this time of year since the water temp is dropping quick.
Glad to also report I'm getting 16.25mpg. Motor appears bone stock except for the air filter/intake. I'm hauling about 600 lbs. in the utility body of gear along with a 100lbs. German Shepherd.
Just starting to hunt through the forums. I'll try to keep from repeating questions.

Don't feel too bad if you repeat a question. These motors aren't exactly new, so there's not many questions that haven't come up before. And don't be shy about jumping in the middle of some thread you're reading and asking a question. It's the best way to learn.
Besides. It's a lot easier to answer the questions that have been asked already.

Welcome to the Club. I see that you are from my neck of the woods. You may want to check the glow plug relay. The WTS light is'nt tied into the glowplugs. The glow plugs can run for up to 2 minutes (IIRC) after the engine has started.
