Hard start,white smoke, boost gauge stuck at 5psi.

[jmcclellan]

I hate to even post something with the white smoke issue but after searching for an hour I haven't found any other threads that sound like my issue. So here it goes. I have a 99 f350 with 208,000 miles. About two weeks ago it started having difficulty starting. While I turn the engine over it billows white smoke that fills the garage or the next two parking stalls over from me. It takes a good 5 to 8 cranks sessions of 15 seconds or more to finally get it to start up. I don't know if the two issues are related or not but about the same time the starting got rough I have noticed a high pitch squeal when I ramp the rpms up and from time to time my boost gauge will stick at 5psi. I don't know if it is boosting all the time it doesn't feel like it but the gauge is reading 5 psi. Sorry again for the white smoke post but any help would be appreciated.

Any DTCs? Whats your coolant level?

check your belt tensioner and belt condition , that could be your squeal . also a loose belt will not fully charge the batterys leading to a low charge not allowing it to spin the engine over fast enough or provide enough power to the glow plugs . also check for corrosion on your battery leads and battery condition . you could also have a problem with your glow plug relay or glow plugs them selves there are several stickys on it .

does the engine boost under load , it wont boost much unloaded .
