Bad injector or injector o-rings?

Hey guys, my truck started up pretty hard this morning. Was about 35f out. I checked all the glow plugs and the relay and all glow plugs read 1.4 ohms and relay worked properly. Once it started it ran fine. However it smokes blue slightly every morning or when it sits long enough for it to get cold regardless of the temperature outside. The smoke goes away after about 5 mins and none when itís warmed up. Truck has no blow by as I checked for that as well. Also burned about half a qt of oil since last oil change(has about 2800 miles since last change). Truck never misses either. Just concerned that it has a bad injector or bad o rings. Any thoughts? Thanks.

Also just wanted add that it blew a big puff of white/grey smoke this morning when it started hard then went right back to its normal blue smoke. Also when I started it up again this afternoon to leave work it started normally. Also truck has 180000 miles and has been very well maintained.

Re: Bad injector or injector o-rings?

How long are you waiting after WTS before cranking it over? It could be injector O-rings, but you won't know for sure. You can look at the fuel filter and see if it looks black, I guess. When I had an injector o-ring failure, it was immediate. I went through 8 quarts in 150 miles! If the O-rings are still original at 180k, that's about when mine went. Cheers!

I usually wait maybe 10 seconds often the wts light and it always fired right up. Maybe I should wait longer. Iíll have to keep an eye on my oil then! Thatís a lot of oil! Thanks for the help Patrick!

Re: Bad injector or injector o-rings?

Mine smokes for about the first 5 minutes. Just a faint blue color, then clears up. It has always done it. Even after I got new injectors put in. Only when it's relatively cold and is a cold start. I would watch the oil level and see if it ever starts to burn more and more as time goes on. I want to say there is a spec for an amount of oil that is expected to be burned over a set amount of miles that I remember reading in the manual, but I could be totally wrong too....

You can hook an LED light to the GPR so that you can monitor when the glow plugs are active or not. The glow plugs should be active for something like 2 minute upon a cold start. They are still active even though the WTS light is out. It's easy and cost about $5 bucks to do.
