Hello everyone I'm new to this site. Tomorrow I will be buying a 2014 Longhorn that's in great condition. It has 191,897k miles, Eco Diesel engine. Is this a good buy?
40k miles a year tells you it was used on the highways so maybe! Do you know how to do a blowby test? Take off the oil fill cap and put your hand over it. Have someone start the engine and see how much is coming back out. Not much, just a whiff? All good. Blowing out like a hairdryer on low? Run.
Next put a code reader on it. See how many and what codes are stored. No doubt they cleared the CEL. Look for EGR related codes.
One thing about used trucks. Everybody trades them in for a reason. Find that reason and make sure you can handle the issue.
