Break-in...
 

Here I go...I sat in the dealer parking lot idleing my new truck waiting for the sales guy to take me out for the test drive.

I forgot Cummins reccomends not idleing the engine more than 5 minutes during break in.

I don't think 10 minutes would have screwed anything up.

10 minutes will not bother it, especially at this time of the year when it is warm out. More trouble at idle when it is COLD ambient temperature.

You're not anxious to get your new truck home are you???[laugh] :D :p

You bet I am Hannibal!

I know the feeling. When I found my '98 CC 5psd/4.10 black/driftwood Laramie, I made them an offer and went home. I waited two weeks for them to call. If I'd have known they were going to call at 5:00pm on a Wednesday, I wouldn't have been up at 3:00am Sunday sitting by the phone. But I played hardball with them just like they were doing to me. They accepted my offer and I traded my '95 auto/3.55 reg cab Cummins for the '98. Then I traded the '98 with 89k miles for an '01.5 auto/3.55 QC LB Laramie. Then in '03 they made them quiet... I had to wait a week to get my '03. It went straight to the shop for a recall on the tranny cooler line. I was on pins and needles all week. I know the feeling!;)
