I have been looking for a while for a duramax to tow my project around. I found one for a hell of a deal and want to know before i go see it what to look for and how to test it to ensure I'm not buying junk. Any help would be appreciated. Thank you!

How to test an 03 duramax before purchase

I know this is an old thread but wanted to answer it any way . You look for diesel in the oil . Oil pressure . Warm it up and see where the pressure is at . Should be over 50 lbs running at 1500 rpms . Then check the bottom front for oil . Could have over flowed oil from fuel in diesel
x2 on this .
my buddy got a 03 and drove it home 550 miles . no problems sounded great real clean . . . untill he check the oil level again . was perfect at the dealer and diesel black color . got home and was 1gal over full and yellowish .
well good thing he can do his own work . 8 injectors hard lines . adjust all valves when open . thankfully she didnt get hurt with the fuel in it . been doing great now for over a year .
you guys are awesome for the help. I bought an 06' and had it throughly checked before purchase. I am currently changing all the fluids anyway. Thank you for your help!
Was going to say check balance rates of the injectors, and check for blowby
