Ok, walmart story.

So i run my 1981 240d pretty hard, its a manual 4 speed. I usually let it sit on the rev limiter in all four gears if i can. (Only to clean it out these engines love to howl) So today i drive to work, just like usual. And before i leave i start the car and let it idle for about fourty five minutes before i leave. Now, before all of this i had added gasoline to the fuel tank with about three gallons of diesel and a quart of engine oil to lubricate the IP. So i get in my car after it idled for allmost an hour, drive off everything is fine, shes howling through her gears. And i drive home, wich i live about an hour away and decide to get some clothes and oil to do an oil change on this car. As im going through the walmart parking lot i let the car get up to about 4k rpms, not on rev limiter but up there and then i glide into my parking spot and let it idle for a few seconds, to cool the oil. I shut it off and get out lock the door and start walking to the walmart entrance, A guy stops me and says "hey how do you get your car to do that?" and he points at my exhaust, and im like... bad paint job? my chrome is falling off? So a girl walking next to him says "hes talking about the sparks coming out of your tailpipe" and im like HUH? sparks?... So i just go "oh, its a diesel" and walk away.

Freaked me out because i thought that it was demolishing itself before i remembered that i let it idle for like forever. and maybie my muffler is falling apart. cool sparks anyone else?

Burning valves from all the junk you are putting through the fuel and the abuse your engine is suffering through.

My thoughts exactly.
Why do you think it's a good idea to put gasoline in your fuel tank. I would suggest that you stop that immediately.

I would also suggest that you stop revving it so much when it's not under load.

I thought any gas in a diesel would ruin it. I guess not completely.

And there is no reason you should idle your engine for forty five minutes. These engines don't get to operating temperature without a load put on them. Start it, wait a minute and drive away. Warms up faster that way.

I had that thought, too. Forty-five minutes of idling with diesel selling for >$4.00 a gal. sounds pretty extravagant.

They don't burn nearly as much fuel in an hour of idling as a comparably sized gasoline engine. It's not that bad.

Burning valves isn't the only thing happening there. Those poor valve seats are taking a terrible beating at the same time.
Do I hear "valve job" in the near future?

That also means they don't warm up. What's the point?

Yeah really....whats the point of letting it idle? Even when its 0F out I only let it idle as long as it takes me to get the snow off the car! (maybe 5-6 mins tops)

You need to stop running that junk through there, it runs on DIESEL, not a "Multi-fuel blend" !

I don't think Busted is recommending idling for 45 minutes.......he's just telling Dee8go that it's not a horrific consumption of expensive fuel.

I guess that's why truck drivers often leave their rigs idling for long periods of time.

Lately I've noticed that I see almost no idling diesels ever, not even the big rigs.....everyone turns them off if it will be more than a few minutes. When I was little I always saw diesels idling. In the big lot at my school where like 18-20 busses would come at the end of the day, they were all always idling. Huge cloud of exhaust.

Thats because those big engines consume around 1gph of fuel even at idle. Our engines are about 1/4 the displacement of them so it would be reasonable to assume we burn around 0.25gph at idle. Still, thats $1 of fuel Cervan will never see again.
