i start my truck and it sounds fine but has a tint of white smoke coming out at first, when i rev my engine even just a little i hear a deep winding down sound around my turbo. i had the check engine light come on fora min then go away then on again fora few min then off. what is going on?

 

You have a fuel pressure guage?

Is this a stock truck?

Have you scanned for codes?

 

Scan it for sure. This will take most of the guess work out of it. Also check your turbo and see if there is too much play on the impeller wheel....possible crapped out bearing comes to mind. Hope it aint serious!

 

yes, inspect the impeller....

 

is there suposed to be any play in it at all? there is a little but nothing insane i remember wigling it around, i haven't gotten it scanned for codes yet im in afghanistan right now i come home in about 20 days

 

A little play is normal, and is needed for thermal expansion.

 

As long as the play isnt sloppy. Scanning is a good place to start. BTW, Thank you for your service to our country. I wish you a safe return.

 

okay i will start there, it just sucks that its 80$ to do the scan its stupid.. and no problem i love to serve

 

For eighty bucks you can buy a decent scanner

 

they sell those?
